           CDAS network now assimilates NOAA-15 and NOAA-16 ATOVS temperature retrievals rather than NOAA-14 RTOVS temperature retrievals (still sampling data at approximately 250 km resolution).  NOAA-14 RTOVS temperature retrievals are no longer dumped in FNL or CDAS networks (these are about to be discontinued by NESDIS).
     09/04/2001/1200UTC:
           NOAA-15 HIRS-3 1B data are again ingested into /dcom BUFR and IEEE database but are not yet dumped or assimilated.
     09/25/2001/1200UTC:

     10/28/2003/1200UTC:
           NOAA-17 AMSU-A data turned off in GFS/GDAS SSI and in EDAS/ETA 3DVAR analysis because instrument is producing bad data due to an antenna anomaly.
     05/25/2004/1200UTC:
           NOAA-16 HIRS-3 data turned off in GFS/GDAS SSI and in EDAS/ETA 3DVAR analysis due to increase in noisiness in the data.

     10/25/2005/1200UTC:

           NOAA-18 HIRS-4 and MHS data now are now dumped ("1bhrs4" and
"1bmhs", resp.) in the GFS, GDAS, CDAS, NAM and NDAS networks. These are not yet monitored nor assimilated by any network.

           NOAA-15 AMSU-B channel 4 turned off in all analyses (went bad per UK Met Office).
     06/20/2006/1200UTC:
           NOAA-18 AMSU-A, MHS and HIRS-4 data now assimilated by NAM/NDAS GSI.
     06/27/2006/1200UTC:
           EUMETSAT ATOVS Retransmission Service (EARS, bulletin header "EUMS") AMSU-A, AMSU-B and HIRS-3 data are now decoded into the /dcom database in tanks b021/xx033, b021/xx034 and b021/xx035, respectively.  These data will eventually be used to fill in gaps in the primary satellite server feed of ATOVS brightness temperature data.  They are currently not dumped, monitored or assimilated in any network.
     09/25/2006:
           NOAA-14 HIRS-2 and MSU data no longer available from NESDIS.  NOAA-14 HIRS-2 and MSU data no longer ingested into /dcom database. Dump files "1bmsu" and "1bhrs2" no longer produced in NAM/NDAS or GFS/GDAS networks.  These data are no longer assimilated by the GFS/GDAS SSI or NAM/NDAS GSI.
     10/19/2006:
           METOP-2 launched into morning orbit.  Was mislabeled as satellite id 3 instead of the correct value of 4 until
04/12/2007/0000UTC.
     04/24/2007/1200UTC:
           METOP-2 AMSU-A, MHS and HIRS-4 data now ingested into /dcom BUFR database and dumped in NAM, NDAS, GFS and GDAS networks (not yet assimilated).

     05/01/2007/1200UTC:
           NOAA-18 MHS data now assimilated by GFS/GDAS GSI (Global-GSI became operational today).
     05/21/2007/000UTC:
           METOP-2 replaces NOAA-17 as the primary morning satellite.  METOP-2 and NOAA-18 (primary afternoon satellite) now form the NESDIS POES constellation.  (NOAA-15, -17 and -16 provide backup support in that order - we still receive data from these satellites although it can be delayed).
     05/29/2007/1200UTC:
           METOP-2 AMSU-A, MHS and HIRS-4 data now assimilated by GFS/GDAS GSI (not yet assimilated by NAM/NDAS GSI).
     11/16/2007/1800UTC:
           NOAA-18 AMSU-A channel 9 is no longer assimilated by the NAM/NDAS or GFS/GDAS GSI.  A sudden increase in the noise for both space and warm counts for this channel has been observed.
     03/06/2008/1200UTC:
           NOAA-16 AMSU-A channel 4 has gone bad.  As a result, NOAA-16 ATOVS sounding files are no longer being produced by NESDIS, thus they are no longer in the "atovs" dumps in the GDAS and CDAS networks and they (temperature retrievals) are no longer available for assimilation by the CDAS.  The "atovs" dumps now contain only NOAA-15 ATOVS soundings and only these temperature retrievals (cloudy only) are assimilated by the CDAS.  In addition, the failed channel 4 data has resulted in no NOAA-16 AMSU-A data being assimilated by the NAM/NDAS or GFS/GDAS GSI (even though these files are still being produced by NESDIS and NOAA-16 AMSU-A data continue to be dumped in the "1bamua" files in the CDAS, GDAS, GFS, NDAS and NAM networks).
     03/12/2008/1200UTC:
           The "satinfo" files have been modified to no longer use (and to just monitor) NOAA-16 AMSU-A data in the NAM/NDAS and GFS/GDAS GSI (even though these files are still being produced by NESDIS and NOAA-16 AMSU-A data continue to be dumped in the "1bamua" files in the CDAS, GDAS, GFS, NDAS and NAM networks).  See 03/06/2008/1200UTC note above for more information.
     03/27/2008/1200UTC:
           ATOVS soundings (retrievals) in /dcom database tank b003/xx104 and in "atovs" dump files in GDAS and CDAS networks now contain NOAA-18 and METOP-2 data [replacing NOAA-15 and the now-defunct NOAA-16 (see 03/06/2008/1200UTC entry above)].  The CDAS now assimilates NOAA-18 cloudy temperature retrievals in place of NOAA-15 cloudy temperature retrievals (PREPBUFR processing is not yet ready to handle data from the METOP-2 satellite).
     06/06/2008/1200UTC:
           The CDAS now assimilates METOP-2 clear and cloudy soundings (in addition to existing NOAA-18 cloudy soundings) (PREPBUFR processing can now handle data from the METOP-2 satellite).
     09/15/2008/1500UTC:
           ATOVS AMSU-A ("1bamua"), AMSU-B ("1bamub"), HIRS-3 ("1bhrs3"), MHS ("1bmhs") and HIRS-4 ("1bhrs4") data now dumped in RUC network.  These data are not assimilated by the RUC analysis.  They will be used by the future (2009) RapidRefresh system.
     12/16/2008/1200UTC:

           METOP-2 AMSU-A, MHS and HIRS-4 data now assimilated by NAM/NDAS GSI.
     01/15/2009/1200UTC:
           METOP-2 AMSU-A channel 7 is no longer assimilated by the NAM/NDAS or GFS/GDAS GSI.  A sudden increase in the noise-equivalent delta-t for this channel has been observed in the past week.
     02/09/2009/1022UTC:
           NOAA-N-prime launched and now in afternoon orbit as NOAA-19.
     04/17/2009/2000UTC:
           NOAA-16 AMSU-B brightness temperatures are no longer assimilated by the NAM/NDAS or GFS/GDAS GSI (but they are monitored by both). This is due to a degradation in the quality of channel 19.
     06/02/2009/000UTC:
           NESDIS declares NOAA-19 operational.  NOAA-19 replaces NOAA-18 as the primary afternoon satellite.  NOAA-19 and METOP-2 (primary morning satellite) now form the NESDIS POES constellation.  (NOAA-18, -17, -15 and -16 provide backup support in that order - we still receive data from these satellites although it can be delayed).  We have not yet moved to operational use of NOAA-19 in any system.
     06/02/2009
           NOAA-15 HIRS-3 data are no longer ingested into /dcom, nor are they included in the "1bhrs3" dumps in the
GFS, GDAS, CDAS, NAM and NDAS networks.  This is due to every scan failing calibration checks.  There is a major problem with this instrument.  NCEP has not used these data in any assimilation since 11/2000.
     09/29/2009/1500UTC:
           NOAA-19 HIRS-4, AMSU-A and MHS data are now ingested into /dcom database and are now 
dumped (included in "1bhrs4", "1bamua" and "1bmhs", resp.) in the GFS, GDAS, CDAS, NAM and NDAS networks.  These are not yet monitored nor assimilated by any network.
     10/27/2009/1200UTC:
           EUMETSAT ATOVS Retransmission Service (EARS
, bulletin header "EUMS") AMSU-A, AMSU-B and HIRS-3/-4 data are now dumped in the GFS and GDAS networks into files "esamua", "esamub" "eshrs3", respectively.  These data will eventually be used to fill in gaps in the primary satellite server feed of ATOVS brightness temperature data.  They are currently not dumped in any other network, nor are they monitored or assimilated in any network.
     11/24/2009/1200UTC:
           Some of the Asia-Pacific Regional ATOVS Retransmission Service (AP-RARS, bulletin headers "RJTD", "AMMC" and "NZGP")
AMSU-A, AMSU-B and HIRS-3/-4 data are now added to existing EUMETSAT ATOVS Retransmission Service (EARS, bulletin header "EUMS") data in /dcom tanks b021/xx033, b021/xx034 and b021/xx035, and GFS and GDAS network dump files "esamua", "esamub" "eshrs3", respectively.  The combined data are referred to as Regional ATOVS Retransmission Services (RARS).  These data will eventually be used to fill in gaps in the primary satellite server feed of ATOVS brightness temperature data.  They are currently not dumped in any other network, nor are they monitored or assimilated in any network.  We are still awaiting the remaining AP-RARS data (bulletin headers "BAWX", "RKSL", "VHHH" and "WSSS") as well as all of the South American-RARS (SA-RARS) data (bulletin headers "SBBR" and "SABM").
     12/01/2009 (or thereabouts):
           The 
EUMETSAT ATOVS Retransmission Service (EARS, bulletin header "EUMS") data are no longer being ingested due to a glitch in NCO data flow's bulletin header pattern matching processing.
     12/15/2009/1500UTC:
           NOAA-19 AMSU-A and HIRS-4 data are now assimilated by the GFS/GDAS GSI.  NOAA-19 MHS data are now monitored by the GFS/GDAS GSI.  The NAM/NDAS GSI does not yet use or even monitor any of these NOAA-19 1B data.  The following Regional ATOVS Retransmission Services (RARS) 1C data are now assimilated by the GFS/GDAS GSI: AMSU-A from NOAA-15, NOAA-18 and NOAA-19; AMSU-B from NOAA-15 and NOAA-17.  
The following RARS 1C data are now monitored by the GFS/GDAS GSI: AMSU-A from NOAA-16, AMSU-B from NOAA-16.  The NAM/NDAS GSI does not yet use or even monitor any RARS data (they are not yet even dumped in the NAM or NDAS networks).
     12/22/2009/1200UTC:
           All NOAA-17 AMSU-B channels which had been set to "use" were changed to "monitor" in the GFS/GDAS and NAM/NDAS GSI due to calibration problems in these channels.
     01/11/2010/1700UTC:

           NOAA-19 AMSU-A channel 8 is no longer assimilated by the GFS/GDAS GSI (it is now only monitored).  A sudden increase in the noise-equivalent delta-t for this channel has been observed in the past two weeks.
     03/16/2010/1400UTC:
           The remaining Asia-Pacific Regional ATOVS Retransmission Service (AP-RARS) bulletin headers ("BAWX", "RKSL", "VHHH" and "WSSS") as well as all of the South American-RARS (SA-RARS) data (bulletin headers "SBBR" and "SABM") not included in the ingest implementation on 11/24/2009 are now added to existing Regional ATOVS Retransmission Services (RARS) AMSU-A, AMSU-B and HIRS-3/-4 data in /dcom tanks b021/xx033, b021/xx034 and b021/xx035, and GFS and GDAS network dump files "esamua", "esamub" "eshrs3", respectively. The EUMETSAT ATOVS Retransmission Service (EARS, bulletin header "EUMS") data are again being ingested into RARS AMSU-A, AMSU-B and HIRS-3/-4 /dcom tanks b021/xx033, b021/xx034 and b021/xx035, and GFS and GDAS network dump files "esamua", "esamub" "eshrs3", respectively. (These had not been available since early December 2009 due to a glitch in NCO data flow's bulletin header pattern matching processing.)  There is no change to what is being assimilated (see notes from 12/15/2009/1500UTC above to determine what is assimilated).
     03/16/2010/1400UTC:
          
Regional ATOVS Retransmission Services (RARS) MHS data from all sources are now decoded into the /dcom database in tank b021/xx036.  They are currently not dumped, monitored or assimilated in any network.
     10/05/2010/1200UTC:
          
Regional ATOVS Retransmission Services (RARS) MHS data from all sources are now dumped ("esmhs") in the CDAS, GDAS and GFS networks.  They are currently not monitored or assimilated in any network.
     03/28/2011/2300UTC:
           NOAA-15 AMSU-B data are no longer being processed by NESDIS.   The scan motor in inoperable and cannot be fixed. Both the GFS/GDAS and NAM/NDAS GSI had been assimilating these radiances.  Files are still being created by NESDIS, but all records fail NESDIS' calibration quality checks. NCEP is no longer attempting to process these data as of 06/14/2011/1200UTC.
     05/09/2011/1200UTC:
           
NOAA-19 MHS data are now assimilated by the GFS/GDAS GSI (they had been monitored).  GFS/GDAS GSI set to not consider NOAA-15 AMSU-B data any longer.  These data went bad on 03/28/2011 and had not been available since that time.  GFS/GDAS GSI set to no longer monitor NOAA-16 HIRS-3, AMSU-A or AMSU-B data or NOAA-18 HIRS-4 data (these data are no longer considered).
     10/18/2011/1200UTC:
           NOAA-19 AMSU-A and HIRS-4 data are now assimilated by the NAM/NDAS GSI and NOAA-19 MHS data are now monitored by the NAM/NDAS GSI (none had not even been monitored except in parallel).  
NAM/NDAS GSI set to attempt to monitor (rather than attempt to use) NOAA-15 AMSU-B data.  These data went bad on 03/28/2011 and had not been available since that time. At some point they should no longer be considered as with the GFS/GDAS GSI.  NAM/NDAS GSI set to not consider NOAA-17 AMSU-A data any longer (they had been set to "monitor" but these data went bad in October 2003 and have not been available since that time).  NAM/NDAS GSI set to not consider NOAA-14 HIRS-2 and MSU data any longer (they had been set to "use" but these data went bad in September 2006 and have not been available since that time).
     09/17/2012:
           METOP-1(B) launched into morning orbit.
     12/13/2012/1800UTC:
           NOAA-17 HIRS-3 brightness temperatures are no longer assimilated by the NAM/NDAS or GFS/GDAS GSI (but they are monitored by both). This is due to a degradation in the quality of channels 2-20.

    ~10/16/2012:
           METOP-1(B) AMSU-A, MHS, HIRS-4 1B brightness temperatures available on NESDIS' DDS server.  NCEP is not yet processing these data.

     04/11/2013:
           METOP-1(B) ATOVS soundings (retrievals) available on NESDIS' DDS server.  NCEP is not yet processing these data.
     02/19/2013/1200UTC:
           METOP-1(B) AMSU-A, MHS and HIRS-4 1B 
brightness temperatures ingested into /dcom tanks b021/xx023, b021/xx027 and b021/xx028, respectively, (along with the other pre-existing satellites) and are now included in the "1bamua", "1bmhs" and "1bhrs4" dumps, respectively, in all applicable networks.  All are monitored by GFS/GDAS GSI (not considered by any other systems).  METOP-1(B) uncorrected AMSU-A antenna temperatures ingested into /dcom tank b021/xx123 (along with the other pre-existing satellites) (not dumped or assimilated).
     05/01/2013:

All are monitored by GFS/GDAS GSI (not considered by any other systems).

  OZONE (SBUV-2 AND GOME-2) DATA HISTORY ---

     1998 (??):
           NOAA-09 SBUV-2 data processing initiated in Global SSI (AVN and FNL) (data in IEEE format in /dcom database).
     06/08/1998/1400UTC:
           NESDIS discontinues TOVS processing.  AVN and FNL networks discontinue assimilation of TOVS ozone for their 1b processing.  They do not switch to RTOVS ozone due to imminent upgrade of 1B which will no longer need ozone.

     05/14/2001/1200UTC:
           NOAA-16 SBUV-2 data from IEEE dumps now assimilated by GBL-SSI.
     09/11/2002/1200UTC:
           NOAA-17 SBUV-2 data are now included in the various network "osbuv" dump files (they are not yet assimilated by any analyses).  The NOAA-17 data will NOT be included in the operational IEEE dumps. 
     10/29/2002/1200UTC:
           IEEE dumps are no longer generated in AVN or FNL networks.    
     
05/14/2003:
           NESDIS stopped making NOAA-11 SBUV-2 ozone data.

     11/29/2005/1200UTC:
           NOAA-17 SBUV-2 ozone data now assimilated by GFS/GDAS SSI.

     01/17/2006:
           NESDIS stopped making NOAA-14 SBUV-2 ozone data.  NOAA-14 SBUV-2 data no longer ingested into /dcom database or part of "osbuv" dump files.  These data have not been assimilated by SSI for several years.
     
12/04/2007/1200UTC:
          NESDIS Version 8 BUFR SBUV-2 data from NOAA-16, -17 and -18 now dumped into "osbuv8" files in GFS and GDAS networks.  These data replace NESDIS Version 6 BUFR SBUV-2 data (in existing "osbuv" dump) in GFS/GDAS GSI assimilation (NOAA-18 still not assimilated).
     02/04/2008/1200UTC:
          NESDIS stops producing Version 6 BUFR SBUV-2 data (both orbital and daily files).  The "osbuv" dumps are no longer generated in the GFS and GDAS networks.  Daily Version 8 BUFR SBUV-2 files from NOAA-16, -17 and -18 are now copied into daily /dcom database mobsbfr subdirectory, replacing daily Version 6 BUFR SBUV-2 files.
     03/27/2008/1200UTC:
          METOP-2 GOME-2 data now ingested into /dcom database (tank b008/xx012) (not yet dumped or assimilated).
     09/16/2008/1500UTC:
          METOP-2 GOME-2 data are now dumped ("gome") in the GFS, GDAS and CDAS networks.  No  GOME data are yet assimilated or even monitored by any NCEP analysis.
     09/17/2008/1200UTC:
          N-16/17 SBUV-2 data with profile ozone quality flag 7 (upper level profile anomaly or stray light anomaly) are now assimilated in the GFS and GDAS networks by the GBL-GSI (improves coverage in S.H.).
     10/17/2008:
          NOAA-16 SBUV-2 data began to exhibit a high bias along with a large increase in error codes.  The problem was traced to a calculated interrange ratio.
     10/21/2008/1800UTC:

          NOAA-16 SBUV-2 ozone observations are turned off (w.r.t. assimilation) in the GFS/GDAS GSI in order to prevent degradation of GDAS analyses, GFS forecasts of ozone, and stratospheric temperature.
     10/26/2008:
          NESDIS has deemed the NOAA-16 SBUV-2 data to again be of good quality.  However, the equator crossing time for N-16 is now past 1700 local, so about 1/3 of the data are flagged for high solar zenith angle and global coverage is very lopsided.  These have not been turned back on in the GFS/GDAS GSI.
     08/25/2009/1500UTC:
          NOAA-19 orbital SBUV-2 data now ingested into /dcom database (part of existing tank b008/xx011) and included in existing "osbuv8" dumps in the GFS and GDAS networks (not yet assimilated).  Daily BUFR SBUV-2 file from NOAA-19 now copied into daily /dcom database mobsbfr subdirectory.

     12/01/2009/1200UTC:

     12/15/2009/1500UTC:
          NOAA-18 orbital SBUV-2 data are now assimilated by the GFS/GDAS GSI.  NOAA-19 orbital SBUV-2 data and METOP-2 GOME-2 data are now both monitored by the GFS/GDAS GSI.  The NAM/NDAS GSI does not yet use or even monitor any orbital SBUV-2 or GOME-2 data.
     05/09/2011/1200UTC:
          NOAA-19 orbital SBUV-2 data are now assimilated by the GFS/GDAS GSI (they had been monitored).
     09/17/2012:
          METOP-1(B) launched into morning orbit.
     05/15/2013:
          METOP-1(B) GOME-2 data available on NESDIS' DDS server.  NCEP is not yet processing these data. (They initially had the incorrect BUFR satellite id of 4 when they should have been set to 3.)


  SST DATA HISTORY ---

     10/01/2008:
          NAVOCEANO SST files now include METOP-2 data (in addition to existing NOAA-17 and -18 data). (NESDIS SST files continue to include NOAA-16, -17, -18 and METOP-2.)
     06/02/2009:
          NESDIS SST files replace NOAA-16 with NOAA-19 (still include NOAA-17, -18 and METOP-2 data). (NAVOCEANO SST files continue to include NOAA-17, -18 and METOP-2.)  On 06/09/2009/1200UTC NCEP POES SST processing was modified to recognize NOAA-19 and drop NOAA-18.
     06/25/2009/2000UTC:
          METOP-2 replaces NOAA-17 in the generation of physical POES SST retrievals generated from AVHRR brightness temperatures from both NAVOCEANO and NESDIS sources.  NOAA-18 also input, as before.
     07/07/2009:
          NAVOCEANO SST files no longer include NOAA-17 data (only METOP-2 and NOAA-18 data are now in these files). (NESDIS SST files continue to include NOAA-17, -18, -19 and METOP-2.)
     12/15/2009/1800UTC:
          NAVOCEANO SST files now include NOAA-19 data (in addition to existing METOP-2 and NOAA-18 data). (NESDIS SST files continue to include NOAA-17, -18, -19 and METOP-2.)
     12/13/2010/1700UTC:
          NESDIS SST files no longer include NOAA-17 data (only NOAA-18, NOAA-19 and METOP-2 data are now in these files). (NAVOCEANO SST files continue to also include NOAA-18, -19 and METOP-2.)
     10/11/2011/1800UTC:
          NOAA-19 replaces NOAA-18 in the generation of physical POES SST retrievals generated from AVHRR brightness temperatures from both NAVOCEANO and NESDIS sources.  METOP-2 is also input, as before.
     04/24/2012/1200UTC:
          Albedo is now stored in channel 3 for the morning POES satellites (currently only METOP-2) during the daytime hours (for both NAVOCEANO and NESDIS sources).  Brightness temperatures continue to be stored in channel 3 for all afternoon POES satellites (currently NOAA-18 and -19) and for the morning POES satellites during nighttime hours.  Prior to this, albedo was erroneously stored as an invalid brightness temperature 
for the morning POES satellites during the daytime hours.
     09/17/2012:
          METOP-1(B) launched into morning orbit.

           GOES-12 launched.

     04/01/2003/1800UTC:
           GOES-12 replaced GOES-08 as the eastern North American NESDIS geostationary satellite.

     06/07/2005/1600UTC:
           GOES winds from the GTS are now being ingested into /dcom database by the NCO decoder system (the winds from NESDIS server gp12 are still written into the various network PREPBUFR files and assimilated by the operational analyses).

     05/24/2006:
           GOES-N launched and became GOES-13 on 6/4/2006.
     06/21/2006/1800UTC:
           GOES-11 replaces GOES-10 as the operational West satellite.  GOES-11 winds are being assimilated in place of GOES-10.  GOES-12 remains the operational East satellite.
     12/04/2007/1800UTC:
           GOES-12 (GOES-E) data are temporarily not available.  The satellite experienced an anomaly in its attitude due to an oxidizer leak in an attitude thruster following a scheduled North-South station keeping maneuver.  The estimated return to service date for GOES-12 is 12/17/2007. Until then, GOES-10 is being utilized with the GOES-E schedule.
     12/
07/2007/0000UTC:
           NCEP began to receive GOES-10 IR, visible, water vapor winds in the GOES-E BUFR files from NESDIS' GP12 server.  The NAM/NDAS and GFS/GDAS GSI are assimilating GOES-11 and  now GOES-10 IR and imager water vapor (cloud top) winds and are monitoring GOES-11 and now GOES-10 visible winds.  The RUC is assimilating GOES-11 and now GOES-10 IR and imager water vapor (cloud top and deep layer) winds.
     12/18/2007/0000UTC:
           GOES-12 data once again available, replacing GOES-10 in the GOES-E BUFR files from NESDIS' GP12 server.
 The NAM/NDAS and GFS/GDAS GSI are again assimilating GOES-11 and GOES-12 IR and imager water vapor (cloud top) winds and are monitoring GOES-11 and GOES-12 visible winds.  The RUC is assimilating GOES-11 and GOES-12 IR and imager water vapor (cloud top and deep layer) winds.
     12/15/2008/0500UTC:
           GOES-12 (GOES-E) data are not available due to a thruster anomaly.  The estimated return to service date for GOES-12 is uncertain. Until then, GOES-13 is being utilized with the GOES-E schedule.  All NCEP analysis that had been using GOES-12 winds are now using GOES-13 winds.
     01/06/2009/1800UTC:
           GOES-12 returned to service and replaced GOES-13 as GOES-E.
All applicable NCEP analysis are again using GOES-12 winds.  (The last GOES-13 winds were processed on 1/06/2009/1600 UTC.)
     05/24/2006:
           GOES-O launched and became GOES-14 on 6/27/2009.
     12/1/2009:
           GOES-10 is decommissioned.
     03/04/2010:
           GOES-P launched and will become GOES-15 when it reaches final orbit.
     04/14/2010/1800UTC:
           GOES-13 replaces GOES-12 as the operational East satellite.  GOES-13 winds are being assimilated in place of GOES-12.  GOES-11 remains the operational West satellite.
  
     09/28/2010/1200UTC:
           Data now dumped in
the RTMA network (as part of "satwnd") and are now encoded into the PREPBUFR file and IR and water vapor imager (cloud-top and deep layer) winds are assimilated by the 5 km CONUS, and Alaska, Guam, Hawaii and Puerto Rico RTMA runs.
     12/06/2011/1500UTC:
           GOES-15 replaces GOES-11 as the operational West satellite.  GOES-15 winds are being assimilated in place of GOES-11.  GOES-13 remains the operational East satellite.

     05/22/2012/1200UTC:
           The GFS/GDAS GSI now reads in all satellite-derived wind data from the "satwnd" rather than from the "SATWND" messages in the GFS and GDAS PREPBUFR files.  "SATWND" messages are still written to the GFS and GDAS PREPBUFR files but are not used. All other networks that assimilate s
atellite-derived wind data continue to read these from the "SATWND" messages in their respective PREPBUFR files.  The GFS/GDAS GSI now assimilates JMA water vapor imager cloud-top winds (it had just monitored them).  It continues to monitor JMA water vapor imager deep-layer winds.
     09/23-24/2012:
           The GOES-13 (East) imager instrument (and sounder instrument) has degraded in quality due to an anomaly and went out of service on 09/23/2012/2122UTC. On 09/24/2012/0030UTC, NESDIS began sending GOES-15 (West) data into the East files.  We were then getting duplicate wind data but these were successfully removed in the dumpjb duplicate-checking process.  On 09/24/2012/1745UTC, NESDIS began sending GOES-14 data into the East files.  All NCEP analyses that had used GOES-13 satellite-derived winds were then using GOES-14 satellite-derived winds (effective with the 00z 09/25 GFS and NDAS).  GOES-14 is currently positioned at 105W but will soon begin to drift eastward towards the location of GOES-13 at 75W.
     10/18/2012/1444UTC:
           NESDIS is switching GOES-E satellite back to GOES-13 (from temporary GOES-14, see above).  All NCEP analyses that had previously used GOES-13 (and then GOES-14) satellite-derived winds will again use GOES-13 satellite-derived winds.
     05/22/2013/0340UTC:
           The GOES-13 (East) satellite has been affected by an anomaly which has shut down the imager (and sounder) instruments. The last cycles to receive GOES-13 data were: 00z 05/22 - GDAS, GFS, NAM, 03z 5/22 - NDAS (12z 5/22 tm09), 04z 5/22 - RAP.  On 05/23/2013/0600UTC, NESDIS began the process of sending GOES-14 data into the East files.  All NCEP analyses that had used GOES-13 satellite-derived winds were then using GOES-14 satellite-derived winds (effective with the 12z 05/23 RAP, NAM, GFS and GDAS).  GOES-14 is currently positioned at 105W.  There are no plans now to move GOES-14 from its current position.

     04/01/2003/1800UTC:
           GOES-12 replaced GOES-08 as the eastern North American NESDIS geostationary satellite.
     07/08/2003/1200UTC:

     06/06/2006/1200UTC:
           Implementation of NAM/NDAS GSI discontinues use of GOES 5x5 field-of-view layer precipitable water retrievals (although they are still monitored).  GOES 5x5 field-of-view sounder radiances still read from PREPBUFR file and still used over water only.  The NDAS forecast component no longer (for now) uses the GOES 1x1 field-of-view cloud top data (it is still generated hourly in dump and mini-PREPBUFR files).
     06/21/2006/1800UTC:
           GOES-11 replaces GOES-10 as the operational West satellite.  GOES-11 5x5 field-of-view sounder radiance data, layer PW retrievals and 1x1 field-of-view cloud top data are not yet being assimilated in any NCEP network.  GOES-12 remains the operational East satellite - its 5x5 field-of-view sounder radiance data are being assimilated (over water only) at NCEP.
     02/06/2007/1200UTC: 
           GOES-11 5x5 field-of-view clear layer PW retrievals and 1x1 field-of-view cloud top data are now assimilated by RUC.
     02/21/2007/1200UTC:
           GOES-11 and -12 1x1 field-of-view soundings/retrievals/radiances now ingested in /dcom database (into tank b003/xx003) and dumped in GFS, GDAS, NAM and NDAS networks (dump file "goesfv") [these will never be written into PREPBUFR files, not yet assimilated, 5x5 field-of-view data (originally in dump file "goesnd") are still assimilated from PREPBUFR files].  GOES-11 1x1 field-of-view soundings/retrievals/radiances and experimental ("new-science") cloud top data were mislabeled as satellite id 254 instead of the correct value of 255 from 07/19/2006 until 08/23/2006 and then again starting from sometime between 12/01/2006 and 02/28/2007 until 03/20/2007.
     05/29/2007/1200UTC:
           GOES-11 and -12 1x1 field-of-view sounder radiances over water now assimilated by GFS/GDAS GSI directly from dump file "goesfv" (not yet assimilated by NAM/NDAS GSI). GOES-12 5x5 field-of-view sounder radiances are no longer assimilated over water by GFS/GDAS GSI (GOES-11 5x5 field-of-view sounder radiances were never assimilated by GFS/GDAS GSI, nor were any over land sounder radiances; the NAM/NDAS GSI continues to assimilate GOES-12 5x5 sounder radiances over water).
     12/04/2007/1200UTC:
           GOES-11 and -12 5x5 field-of-view sounder radiances (dump file "goesnd") are no longer dumped or written into PREPBUFR file GFS and GDAS networks.  [These were replaced in GFS/GDAS GSI assimilation by 1x1 field of view sounder radiances (in dump file "goesfv") on 5/29/2007 (see above).]
     12/04/2007/1800UTC:
           GOES-12 (GOES-E) data are temporarily not available.  The satellite experienced an anomaly in its attitude due to an oxidizer leak in an attitude thruster following a scheduled North-South station keeping maneuver.  The estimated return to service date for GOES-12 is 12/17/2007. Until then, GOES-10 is being utilized with the GOES-E schedule.
     12/05/2007/1600UTC:
           NCEP began to receive GOES-10 sounding/retrieval/radiance data in the GOES-E BUFR files from NESDIS' GP12 server.
                In the 1x1 field-of-view files (non-cloud), GOES-10 was incorrectly assigned BUFR satellite id 255 (that of GOES-11) instead of the correct value 254.  Thus, data from both GOES-E and GOES-W was processed as GOES-11 by NCEP.  This caused major problems in the GFS/GDAS GSI resulting in the eventual switching off of the assimilation of all GOES 1x1 field-of-view sounder radiances in the GFS/GDAS GSI effective 12/10/2007/1800UTC.  In the meantime, NESDIS corrected GOES-10 BUFR files to use the proper satellite id 254 effective 12/10/2007/1800 UTC.  The GFS/GDAS GSI will continue to monitor GOES-11 1x1 field-of-view sounder radiances (it does not monitor these data from GOES-10).  Once GOES-12 returns to service, the GOES-11 and GOES-12 radiances will be evaluated carefully before any decision is made to re-introduce them into the GFS/GDAS GSI assimilation.
                In the 5x5 field-of-view files, GOES-10 was correctly assigned BUFR satellite id 254. The NAM/NDAS GSI is now assimilating GOES-10 5x5 field-of-view sounder radiances in place of GOES-12 (it does not assimilate these data from GOES-11).  The RUC is now assimilating only GOES-11 5x5 field-of-view layer PW retrievals (normally it also assimilates these data from GOES-12; it does not assimilate these data from GOES-10).
                In the 1x1 field-of-view cloud top data files, GOES-10 was correctly assigned BUFR satellite id 254. The RUC is now assimilating only GOES-11 1x1 field-of-view cloud top data (normally it also assimilates these data from GOES-12; it does not assimilate these data from GOES-10).
     12/17/2007/1800UTC:
           GOES-12 data once again available, replacing GOES-10 
in the GOES-E BUFR files from NESDIS' GP12 server.
                In the 1x1 field-of-view files (non-cloud), GOES-11 and GOES-12 sounder radiances are again being assimilated in the GFS/GDAS GSI effective 12/18/2007/1800UTC.
                In the 5x5 field-of-view files, the NAM/NDAS GSI is now again assimilating GOES-12 sounder radiances (it does not assimilate these data from GOES-11).  The RUC is now again assimilating GOES-11 and GOES-12 5x5 field-of-view layer PW retrievals.
                In the 1x1 field-of-view cloud top data files, the RUC is now again assimilating GOES-11 and GOES-12 cloud top data.
     03/31/2008/1200UTC:
           GOES-11 and -12 1x1 field-of-view sounder radiances over water now assimilated by NAM/NDAS GSI directly from dump file "goesfv". GOES-12 5x5 field-of-view sounder radiances are no longer assimilated over water by NAM/NDAS GSI (GOES-11 5x5 field-of-view sounder radiances were never assimilated by NAM/NDAS GSI, nor were any over land sounder radiances).
     07/11/2008/2000UTC:
           GOES-11 and -12 "new-science" 1x1 field-of-view cloud top data (based on GOES 1x1 imagery) replaces previous GOES-11 and -12 1x1 field-of-view cloud top data (based on GOES 5x5 imagery).  Ingested into /dcom database (into tank b003/xx002), dumped in RUC and hourly networks, written into the RUC PREPBUFR files and the hourly mini-PREPBUFR files, and assimilated by the RUC.
     09/15/2008/1500UTC:
           GOES-11 and -12 5x5 field-of-view clear and cloudy layer PW retrievals and radiances are no longer dumped {"goesnd") in the NAM and NDAS networks and are no longer written into the NAM and NDAS PREPBUFR files (layer PW has not been assimilated since 2006, 5x5 f-o-v radiances have not been assimilated since early 2008 as 1x1 f-o-v radiances have, since that time, been assimilated directly from the "goesfv" dump file).
     09/15/2008/1500UTC:
           GOES-11 and -12 1x1 field-of-view clear layer PW retrievals and radiances replace previous GOES-11 and -12 5x5 clear layer PW retrievals and radiances in the "goesnd" dump files in the RUC network.  The layer PW data are written into the RUC PREPBUFR files (report types 156/158) and assimilated by the RUC (replacing the 1x1 layer PW data here).  The 1x1 GOES radiance data are also written into the RUC PREPBUFR files (report types 164/174) (the 5x5 radiances were not written in the PREPBUFR file) but are not assimilated by the RUC analysis.  They will be used by the future (2009) RapidRefresh system.  This ends NCEP's use of GOES 5x5 field-of-view data in all networks.
     09/23/2008/1200UTC:
           Hourly dump and mini-PREPBUFR files containing GOES 1x1 field-of-view cloud top data (only) are no longer generated.  The NDAS forecast component has not used these data since 06 June 2006.
     12/09/2008/1200UTC:
           GOES-11 and -12 5x5 field-of-view layer PW retrievals, soundings, and sounder radiances are no longer ingested into the BUFR /dcom database on the NCEP CCS machines.  The RUC (the last network to use any of these data) switched from 5x5 to 1x1 field-of-view layer PW on 9/15/2008.  This ends NCEP's association with GOES 5x5 field-of-view data.
     12/15/2008/0500UTC:
           GOES-12 (GOES-E) data are not available due to a thruster anomaly.  The estimated return to service date for GOES-12 is uncertain. Until then, GOES-13 is being utilized with the GOES-E schedule.  Both the NAM/NDAS and the GFS/GDAS GSI are set to monitor GOES-13 sounder radiances.  The RUC PREPDATA parm cards are set to flag GOES-13 layer PW and cloud data for non-use by the RUC analysis.  GOES-13 imager radiances are not being processed (no NCEP analysis considers GOES imager radiance data).
     01/06/2009/1700UTC:
           GOES-12 returned to service and replaced GOES-13 as GOES-E.  The NAM/NDAS and the GFS/GDAS GSI are again assimilating GOES-12 sounder radiances. The RUC analysis is again assimilating GOES-12 layer PW and cloud data.  GOES-12 imager radiances are again being processed (no NCEP analysis considers GOES imager radiance data)  (The last GOES-13 sounder radiances/layer PW were processed on 1/06/2009/1500 UTC.)
     05/24/2006:
           GOES-O launched and became GOES-14 on 6/27/2009.
     12/1/2009:
           GOES-10 is decommissioned.
     04/14/2010/1800UTC:
           GOES-13 replaces GOES-12 as the operational East satellite.  Both the NAM/NDAS and the GFS/GDAS GSI are set to monitor GOES-13 sounder radiances (they had assimilated most sounder radiance channels over water from GOES-12).  The RUC PREPDATA parm cards are set to flag GOES-13 layer PW and cloud data for non-use by the RUC analysis (the RUC had assimilated GOES-12 layer PW and cloud data).  GOES-13 imager radiances are not yet being processed and GOES-12 imager radiances are no longer available (no NCEP analysis considers GOES imager radiance data). GOES-11 remains the operational West satellite - there is no change in what is assimilated, monitored, or not used.
     05/04/2010/1330UTC:
           GOES-13 11x17 field-of-view clear imager radiance data are now ingested into the /dcom database (into tank b021/xx041, along with existing GOES-11 data).  They are now included in the "geoimr" dumps in the GFS and GDAS networks (no NCEP analysis considers GOES imager radiance data).
     12/06/2011/1500UTC:
           GOES-15 replaces GOES-11 as the operational West satellite.  The GFS/GDAS GSI is set to monitor GOES-15 sounder radiances while the NAM/NDAS GSI does not yet consider them (both had assimilated most sounder radiance channels over water from GOES-11).  The RUC analysis is set to use GOES-15 layer PW (the RUC had also assimilated GOES-11 layer PW and cloud data).  GOES-15 imager radiances now replace those from GOES-11 (no NCEP analysis considers GOES imager radiance data). GOES-13 remains the operational East satellite - there is no change in what is assimilated, monitored, or not used from this satellite.
     05/22/2012/1200UTC:
           GOES-13 and GOES-15 sounder radiances over water are now assimilated by the GFS/GDAS GSI (they had been monitored).
     09/23-24/2012:
           The GOES-13 (East) sounder and imager instruments have degraded in quality due to an anomaly and went out of service on 09/23/2012/1126UTC. On 09/24/2012/0030UTC, NESDIS began sending GOES-15 (West) data into the East files.  We were then getting duplicate sounder radiance and cloud data but these were successfully removed in the dumpjb duplicate-checking process.  On 09/24/2012/1745UTC, NESDIS began sending GOES-14 sounder data into the East files.  The RAP had monitored but not used GOES-13 cloud data from NESDIS.  It will now monitor but not use GOES-14 cloud data from NESDIS. The GFS and GDAS had assimilated GOES-13 sounder radiances.  They will monitor GOES-14 sounder radiances.  The NAM, NDAS and RAP had monitored GOES-13 sounder radiances but will not monitor (much less use) GOES-14 sounder radiances. No NCEP analyses monitor, much less use, any GOES imager radiances. GOES-14 is currently positioned at 105W but will soon begin to drift eastward towards the location of GOES-13 at 75W.

     10/18/2012/1444UTC:
           NESDIS is switching GOES-E satellite back to GOES-13 (from temporary GOES-14, see above).  
The RAP will, as before, monitor but not use GOES-13 cloud data from NESDIS (just as it did for GOES-14). The GFS and GDAS had assimilated GOES-13 sounder radiances prior to the switch, but they will now monitor GOES-13 sounder radiances due to degradation in their quality (they had also monitored GOES-14 sounder radiances).  The NAM, NDAS and RAP had monitored GOES-13 sounder radiances prior to the switch and will continue to do so again now (they had not monitored, much less used, GOES-14 sounder radiances).  No NCEP analyses monitor, much less use, any GOES imager radiances.
     05/22/2013/0340UTC:
           The GOES-13 (East) satellite has been affected by an anomaly which has shut down the imager and sounder instruments. The last cycles to receive GOES-13 data were: 00z 05/22 - NAM, 03z 5/22 - NDAS (12z 5/22 tm09), 04z 5/22 - RAP, 06z 5/22 - GFS,GDAS.  On 05/23/2013/0600UTC, NESDIS began the process of sending GOES-14 data into the East files.  The RAP had monitored but not assimilated GOES-13 cloud data from NESDIS.  It will now monitor but not assimilate GOES-14 cloud data from NESDIS (effective 09z 5/23). The GFS and GDAS had monitored but not assimilated GOES-13 sounder radiances.  They will monitor but not assimilate GOES-14 sounder radiances (effective 06z 5/23).  The NAM, NDAS and RAP had monitored but not assimilated GOES-13 sounder radiances. They will not monitor (much less use) GOES-14 sounder radiances (although they are in the dumps effective 09z 5/23 for the RAP and 12z 5/23 for the NAM). No NCEP analyses monitor, much less use, any GOES imager radiances (although the ingest was switched to process GOES-14 instead of GOES-13 at 13z 5/23 and these are available from NESDIS). GOES-14 is currently positioned at 105W.  There are no plans now to move GOES-14 from its current position.

     ??????????????????:
           EDAS/ETA analyses begin using FNOC SSM/I total precipitable water retrievals, superobed to 1 degree lat/lon.
     01/10/1995/1200UTC:
           Global analyses begin using FNOC total precipitable water retrievals, superobed to 1 degree lat/lon. These are later discontinued at a date unknown.

           F-13 (Sat. no. 7 - odd) replaces F-11 in operations.
     02/1997:
           SSM/I scan data ingested into /dcom database (BUFR), dumped and reprocessed into ON29 form of “spssmi” file, with conversion of data processing to Cray.
     11/15/1997:
           F-10 no longer operational (died).
     02/09/1998/1200UTC:
           SSM/I wind speed retrievals (operational Goodberlet algorithm), superobed to 1 degree lat/lon, now assimilated by new Eta/EDAS 3DVAR analysis.
     04/07/1998/1200UTC:
           SSM/I wind speed and total precipitable water in Global PREPBUFR files are now generated by the NN3 algorithm.  Only the wind speed is currently assimilated by the SSI.

     07/19/2000/1200UTC:
           SSM/I rain rate (superobed) now included in the AVN, FNL and CDAS “spssmi” reprocessed data dump file.  These will eventually be included in the PREPBUFR file and assimilated by the SSI.
     02/12/2001:
           SSM/I rain rate (superobed) assimilated by SSI directly from “spssmi” dump file (not yet included in PREPBUFR file - not yet ready).
     04/24/2001/1200UTC:
           SSM/I rain rate (superobed) now encoded into AVN and FNL PREPBUFR files (these data are still assimilated by SSI directly from “spssmi” data dump file).
     10/18/2003:
           F-16 (BUFR Sat. no. 249) successfully launched.
     06/06/2006/1200UTC:

           Implementation of NAM/NDAS GSI discontinues use of SSM/I total precipitable water retrievals.
     08/15/2006/1330UTC:
           F-15 (BUFR Sat. no. 248) products (wind speed, rainfall rate, wind speed) no longer reprocessed into "spssmi" dump file in ANY network, thus no longer encoded in PREPBUFR file or available for assimilation in ANY network.  Product quality severely degraded due to activation of "RADCAL" by DMSP Satellite Operations Control Center.  Does not affect F-13 satellite.
     08/24/2008/0300UTC:
          F-14 (Sat. no. 247) failed due to an electrical malfunction.  The spacecraft recorder is inoperable and will remain so until further notice.  F-14 data was not being used by any NCEP network anyway (only F-13 data are used).  It was being ingested into /dcom and dumped.
     09/15/2008/1500UTC:
           New dump files "ssmipn" (SSM/I NN3 products) and "ssmit" (SSM/I brightness temps) now generated in the RUC network.  These data are not written into PREPBUFR nor are they assimilated by the RUC analysis.  They will be used by the future (2009) RapidRefresh system.
     12/02/2008/1500UTC:
           The /dcom ingest is no longer attempting to process F-14 (Sat. no 247) files.  These files have not been available since 08/24/2008 (see above).
     09/29/2009/1500UTC:
           DMSP F-16 and F-17 SSM/IS UPP 1B brightness temperatures now ingested into operational /dcom database (into tank b021/xx201) (not yet dumped or assimilated).
     10/27/2009/1200UTC:
           DMSP F-16 and F-17 SSM/IS UPP 1B brightness temperatures now dumped in GFS and GDAS networks as "ssmisu" (not yet assimilated).
     11/19/2009/0203UTC:
           The final recorder on the DMSP F-13 spacecraft
(Sat. no. 246) has failed.  This satellite was the only one remaining that provided SSM/I data to the NCEP analyses.  This is the end of NCEP's use of SSM/I products and brightness temperatures.  In the unlikely event that some stray, degraded data files may still be ingested (prior to a "Request for Change" package to stop attempting to process them which will not be implemented until next month at the earliest), both the GFS/GDAS and NAM/NDAS GSI were modified on 11/24/2009/1900UTC (via convinfo and pcpinfo parm card changes) to no longer assimilate (but only monitor) SSM/I wind speed and SSM/I rainfall rate (the latter was only assimilated by the GFS/GDAS GSI).
     07/06/2010/1200UTC:
           DMSP F-18 SSM/IS UPP 1B brightness temperatures now
ingested into operational /dcom database (into tank b021/xx201) and dumped in GFS and GDAS networks as "ssmisu" (along with existing DMSP F-16 and F-17) (not yet assimilated).   
     09/28/2010/1200UTC:
           SSM/I NN3 data no longer attempted to be dumped ("ssmipn") in
the RTMA network.  These data dumps have been empty since last November.
     10/05/2010/1200UTC:
           SSM/I NN3 product
("ssmipn"), SSM/I brightness temperature ("ssmit") and SSM/I FNOC product ("ssmip") data no longer attempted to be dumped in the CDAS, GDAS, GFS, NAM, NDAS and RUC networks.  These data dumps have been empty since last November and are now no longer dumped in any NCEP network.

     ?????????????????? (prior to 1986):
           We receive 6-hour SATOB format IR and visible winds (they are assimilated).
     02/1997:
           IR and visible wind data ingested into /dcom database (BUFR) and dumped with conversion of data processing to Cray.
     early 2000:
           Began ingesting and dumping 6-hour SATOB format water vapor winds (not assimilated).
     12/12/2000/1500UTC:
           Began ingesting 90-minute ELW IR, visible and water vapor winds into /dcom database (not dumped or assimilated).
     04/24/2001/1200UTC:
           90-minute ELW IR, visible and water vapor winds replace 6-hour SATOB winds in EDAS, ETA, AVN, FNL and CDAS dump networks.  The IR and visible winds are now assimilated by the 3DVAR and SSI in place on the SATOB winds.
     05/14/2001/1500UTC:
           The 6-hour SATOB winds (all types) are no longer decoded into the /dcom database.
     07/01/2002/1200UTC:
           90-minute ELW IR, visible and water vapor wind generation moved ahead 1-hour by EUMETSAT.  Winds are now produced at 0000, 0130, 0300, 0430, 0600, 0730, 0900, 1030, 1200, 1330, 1500, 1630, 1800, 1930, 2100 and 2230 UTC.
     08/20/2002/1200UTC:
           The time window for processing into PREPBUFR file is changed from -1.75 to -0.25 hours about cycle time to -0.75 to +0.75 hours about cycle time in response to EUMETSAT's change on 07/01/2002/1200UTC.
     08/28/2002:
           MSG-1 (METEOSAT-8) launched.
     06/07/2005/1600UTC:
           High-resolution visible and water vapor winds are ingested into /dcom database (not yet dumped or assimilated).

     12/21/2005:
           MSG-2 (METEOSAT-9) launched.

     06/16/2006:
           METEOSAT-7 winds (all types) no longer available from EUMETSAT.  METEOSAT-8 winds are about to be tested from /dcomdev - not in /dcom database yet.
     02/06/2007/1200UTC:
           METEOSAT-5 high-resolution visible and water vapor winds are now dumped.  The visible winds are assimilated, the water vapor winds are flagged so as to not be assimilated.  METEOSAT-8 winds continue to be ingested into /dcomdev (they are not yet dumped or assimilated but are being tested in the GSI).
     02/13/2007:
           METEOSAT-7 replaces METEOSAT-5 as the east satellite.
     02/15/2007/1800UTC:
           METEOSAT-8 winds are now ingested in /dcom database and dumped and encoded into NAM and GBL PREPBUFR (they are monitored but not used by the NAM/NDAS GSI, they are not used by the GBL-SSI).
     04/11/2007/1300UTC:
           METEOSAT-9 replaces METEOSAT-8 as the west satellite.  NCEP data processing is set up to not yet use MSG winds (see 02/15/2007 above), but METEOSAT-9 IR and visible winds were inadvertently being used in the NAM/NDAS GSI and GBL-SSI after the switch from METEOSAT-8.  A CRISIS change to the dump processing on 0000UTC 13 April now fools the data processing codes into thinking METEOSAT-9 is METEOSAT-8, so the MSG winds are again not being used by these assimilation systems.
     04/17/2007/1200UTC:
           NCEP data processing codes can now handle METEOSAT-9, thus codes are no longer fooled into thinking METEOSAT-9 is METEOSAT-8.  METEOSAT-9 is now dumped and encoded into PREPBUFR (like METEOSAT-8, 
they are monitored but not used by the NAM/NDAS GSI, and they are not used by the GBL-SSI).
     12/03/2007/1800UTC:
           EUMETSAT stops sending METEOSAT-9 data (temporarily) while METEOSAT-9 undergoes routine spacecraft decontamination.  EUMETSAT swapped METEOSAT-9 with METEOSAT-8 during this time, but the METEOSAT-8 data are not getting into the /dcom database for reasons unknown.  (Later it was discovered that NCO dataflow was not looking for the METEOSAT-8 bulletins - this was corrected on 06/17/2008.) MSG is monitored by the GFS/GDAS and NAM/NDAS GSI so this is not critical.
     12/11/2007/1200UTC:
           EUMETSAT begins sending METEOSAT-9 data again as spacecraft decontamination is complete. It is being received in the /dcom database.  We never did receive METEOSAT-8 data during the swap period (see
12/03/2007/1800UTC above).
     05/13/2008/2045UTC:
           EUMETSAT stops sending METEOSAT-9 data (temporarily) do to an anomaly in the spacecraft.  EUMETSAT swapped METEOSAT-9 with METEOSAT-8 during this time, but the METEOSAT-8 data are not getting into the /dcom database for reasons unknown.  
 (Later it was discovered that NCO dataflow was not looking for the METEOSAT-8 bulletins - this was corrected on 06/17/2008.) MSG is monitored by the GFS/GDAS and NAM/NDAS GSI so this is not critical.
     05/19/2008/1000UTC:
           EUMETSAT begins sending METEOSAT-9 data again as spacecraft anomaly issue is corrected. It is being received in the /dcom database.  We never did receive METEOSAT-8 data during the swap period (see 05/13/2008/2045UTC above).
     06/17/2008/1200UTC:
           NCO dataflow made a change such that we will now receive METEOSAT-8 data and it should be tanked in the /dcom BUFR database if it ever again replaces METEOSAT-9.  Recall the last two times this happened (12/03/2007 through 12/11/2007 and 05/13/2008 through 05/19/2008) we did not receive METEOSAT-8 data.
     09/15/2008/1500UTC:
          IR, visible and water vapor winds from METEOSAT-7 and -9 are now included in the "satwnd" dump file and the PREPBUFR file in the RUC network (report type 243/253/254).  These data are not assimilated by the RUC analysis.  They will be used by the future (2009) RapidRefresh system.

     12/01/2008/1200UTC:
          EUMETSAT stops sending METEOSAT-9 data (temporarily) while METEOSAT-9 undergoes routine spacecraft decontamination.  EUMETSAT swapped METEOSAT-9 with METEOSAT-8 during this time, but the METEOSAT-8 data are not getting into the /dcom database for reasons unknown.  (Later it was discovered that NCO dataflow was not looking for the METEOSAT-8 bulletins - this was corrected on 12/16/2008.) MSG is monitored by the GFS/GDAS and NAM/NDAS GSI so this is not critical.
     12/09/2008/1200UTC:

          EUMETSAT begins sending METEOSAT-9 data again as spacecraft decontamination is complete. It is being received in the /dcom database.  We never did receive METEOSAT-8 data during the swap period (see
12/01/2008/1200UTC above).
     04/17/2009/0900UTC:
          EUMETSAT stops sending METEOSAT-9 data (temporarily) due to a spurious event onboard METEOSAT-9.  EUMETSAT swapped METEOSAT-9 with METEOSAT-8 at this time and METEOSAT-8 data are getting into the /dcom database. MSG (both METEOSAT-8 and -9) is monitored by the GFS/GDAS and NAM/NDAS GSI.  The swap back to METEOSAT-9 occurred 04/23/2009/0900UTC.
     08/15/2009/1000UTC:
          EUMETSAT stops sending METEOSAT-9 data (temporarily) due to a spurious event onboard METEOSAT-9.  EUMETSAT swapped METEOSAT-9 with METEOSAT-8 at this time and METEOSAT-8 data are getting into the /dcom database. MSG (both METEOSAT-8 and -9) is monitored by the GFS/GDAS and NAM/NDAS GSI.  The swap back to METEOSAT-9 occurred 08/21/2009/0800UTC.

     12/15/2009/1500UTC:
          METEOSAT-9 IR and visible winds are now assimilated by the GFS/GDAS GSI.  METEOSAT-9 water vapor winds continue to be monitored by the GFS/GDAS GSI.  The NAM/NDAS GSI continues to monitor METEOSAT-9 IR, visible and water vapor winds.  The GFS/GDAS and NAM/NDAS GSI continue to monitor METEOSAT-8 IR, visible and water vapor winds.

     09/28/2010/1200UTC:
          Data now dumped in
the RTMA network (as part of "satwnd") and are now encoded into the PREPBUFR file and IR and visible winds from METEOSAT-7 are assimilated by the 5 km CONUS, and Alaska, Guam, Hawaii and Puerto Rico RTMA runs.
     07/05/2012:

          MSG-3 (METEOSAT-10) launched.

          GMS-4    - 151
          GMS-5    - 152
          GOES-9   - 253
          MTSAT-1R - 171
          MTSAT-2  - 172

     ?????????????????? (prior to 1986):
          We receive 6-hour SATOB format IR and visible winds (they are assimilated).
     02/1997:
           IR and visible wind data ingested into /dcom database (BUFR) and dumped with conversion of data processing to Cray.
     early 2000:
           Began ingesting and dumping 6-hour SATOB format water vapor winds (not assimilated).
     06/07/2005/1600UTC:
           High-density winds coming in GTS-BUFR now ingested in /dcom database (will eventually replace low-density SATOB winds which are still dumped and assimilated).
     07/15/2005/0600 UTC:
           MTSAT-1R replaces GOES-9.
     12/04/2007/1200UTC:
           High-density winds coming in GTS-BUFR are now dumped in "satwnd" file and are assimilated. These replace the low-density winds coming in SATOB format which are expected to be discontinued soon by JMA.  (They are still being ingested in /dcom database for the time being.)
     09/15/2008/1500UTC:
           IR, visible and water vapor winds are now included in the "satwnd" dump file and the PREPBUFR file in the RUC network (report type 242/252/250).  These data are not assimilated by the RUC analysis.  They will be used by the future (2009) RapidRefresh system.
     11/15/2009/1200UTC:
           Data outage (all types) began.  Per JMA, due to the failure of image data processing on the MTSAT-1R ground system.  JMA has switched to MTSAT-2 for this processing but we are not getting these data. JMA will announce when the data processing system of MTSAT-1R is recovered.
     11/27/2009/0330UTC:
           JMA resumed wind production (all types) from MTSAT-1R.  NCEP is again receiving and assimilating applicable data.
     08/11/2010/0000UTC:
           MTSAT-2 replaces MTSAT-1R.  A "bug" in the dump processing codes prevented all MTSAT-2 wind reports from being encoded into the appropriate network PREPBUFR files (although they were encoded in the "satwnd" dump files).  Thus none were assimilated.  This was not corrected until 09/30/2010/2000UTC.
  
     09/28/2010/1200UTC:
           Data now dumped in
the RTMA network (as part of "satwnd") and are now encoded into the PREPBUFR file and IR and visible winds are assimilated by the 5 km CONUS, and Alaska, Guam, Hawaii and Puerto Rico RTMA runs.
     10/07/2010/0600UTC:
           JMA switched from MTSAT-2 to MTSAT-1R due to failure of image data processing on the MTSAT-2 ground data processing system. This was corrected on 10/12/2010 but JMA will not switch back to MTSAT-2 until 12/22/2010.  NCEP is assimilating MTSAT-1R in place of MTSAT-2.
     12/22/2010/0300UTC:
           JMA switched from MTSAT-1R back to MTSAT-2.  NCEP is again assimilating MTSAT-2.
     03/03/2011/0300UTC:
           NCEP started receiving hourly satellite-derived winds from JMA.  They had been produced every three hours.     
     11/01/2011/0300UTC:
           JMA temporarily switched from MTSAT-2 to MTSAT-1R in order to perform ground system maintenance.  
NCEP is assimilating MTSAT-1R in place of MTSAT-2.
     12/26/2011/0300UTC:
           JMA switched from MTSAT-1R back to MTSAT-2.
     10/18/2012/0300UTC:
           JMA temporarily switched from MTSAT-2 to MTSAT-1R in order to perform ground system maintenance.  NCEP is assimilating MTSAT-1R in place of MTSAT-2.
     12/26/2012/0300UTC:
           JMA switched from MTSAT-1R back to MTSAT-2.
     10/22/2013/0300UTC:
           JMA temporarily switched from MTSAT-2 to MTSAT-1R in order to perform ground system maintenance.  NCEP is assimilating MTSAT-1R in place of MTSAT-2.  JMA is expected to switch back to MTSAT-2 on 12/19/2013/0200 UTC.

     05/22/2012/1200UTC:
          GPS-RO bending angle from COSMIC satellite series, METOP-2/GRAS, GRACE-A, SAC-C, TerraSAR-X and C/NOFS are now assimilated by the GFS/GDAS GSI (they had been monitored). GPS-RO refractivity from COSMIC satellite series, METOP-2/GRAS, GRACE-A, SAC-C, TerraSAR-X and C/NOFS are now monitored by the GFS/GDAS GSI (they had been assimilated).

           The GOES-13 (East) sounder instrument (and imager instrument) has degraded in quality due to an anomaly and went out of service on 09/23/2012/1126UTC. On 09/24/2012/0030UTC, NESDIS began sending GOES-15 (West) data into the East files.  We were then getting duplicate cloud data but these were successfully removed in the dumpjb duplicate-checking process.  On 09/24/2012/1745UTC, NESDIS began sending GOES-14 data into the East files.  The RAP had used GOES-13 cloud data from LaRC.  It will now use GOES-14 cloud data from LaRC. GOES-14 is currently positioned at 105W but will soon begin to drift eastward towards the location of GOES-13 at 75W.
     10/18/2012/1444UTC:
           NESDIS is switching GOES-E satellite back to GOES-13 (from temporary GOES-14, see above).  The RAP will, as before, use GOES-13 cloud data from LaRC (just as it did for GOES-14).
     05/22/2013/0340UTC:
           The GOES-13 (East) satellite has been affected by an anomaly which has shut down the sounder (and imager) instruments. The last RAP cycle to receive GOES-13 data was 03z 5/22.  On 05/23/2013/0600UTC, NESDIS began the process of sending GOES-14 data into the East files.  
The RAP had used GOES-13 cloud data from LaRC.  It will now use GOES-14 cloud data from LaRC (effective 17z 5/23 - the ingest was switched to process GOES-14 instead of GOES-13 at 13z 5/23 and LaRC started processing GOES-14 at 16z 5/23).  GOES-14 is currently positioned at 105W.  There are no plans now to move GOES-14 from its current position.

ATMS radiances and brightness temperatures are being ingested into /dcomdev (into tank b021/xx203) and dumped in checkout for testing.
     02/14/2012/1200UTC:
           ATMS radiances and brightness temperatures ingested into operational /dcom database (into tank b021/xx203) and dumped ("atms") in the CDAS, GDAS and GFS networks.  No data are yet assimilated.
     05/22/2012/1200UTC:
           ATMS radiances are now assimilated by the GFS/GDAS GSI.
     10/02/2012/1200UTC:
           CrIS radiances and brightness temperatures ingested into operational /dcom database (into tank b021/xx202) and dumped ("cris") in the CDAS, GDAS and GFS networks.  No data are yet assimilated.  They are monitored by the GFS/GDAS GSI.
