NOAA
Profiler Network (NPN) winds now used in RGL analysis. (Also in
RUC??)
11/05/1997/1200UTC:
VAD winds generated from Radar Coded
Message are now used in the GBL
analysis (not yet used in the RGL analysis). NOAA
Profiler Network (NPN) winds are now used in the GBL analysis.
NPN wind profiler reports are QC'd until the NWS/AirDAT contract is
renegotiated. This could be 2-3 weeks. by the new
program PROFCQC, in
the GBL only.
02/09/1998/1200UTC:
RGL-3DVAR implementation
resulted VAD winds generated from Radar Coded Message now
being used in the RGL analysis.
01/08/1999/1900UTC:
VAD winds generated from
Radar Coded Message are no longer being used
in the RGL and GBL analyses due to quality issues.
11/10/1999/1000UTC:
NPN wind profiler reports are now
QC'd by the program PROFCQC in the RGL and RUC networks (as they had
been in the GBL networks).
03/29/2000/1200UTC:
VAD wind reports generated
from Radar Coded Message are now QC'd by the
new program CQCVAD. All reports with a low RMSVE are now again
used in the RGL and GBL analyses.
01/09/2001/1200UTC:
Tropical wind profilers that arrive
disguised as PIBAL reports are now correctly processed as profilers and
are used in the RGL (unlikely any present in domain) and GBL analyses.
09/10/2002/1500UTC:
JMA wind profiler data are now
encoded into BUFR tanks b002/xx013 in /dcom.
07/2003:
NPN wind profiler surface data now
decoded into /dcom tank b000/xx008.
04/13/2004/1200UTC:
JMA wind profiler and CAP wind
profiler data are added to "proflr" dump - they are not yet written
into PREPBUFR or assimilated in any network.
01/25/2005/1200UTC:
Program PROFCQC, which QC's wind
profiler data, has been upgraded. JMA wind profiler
data now encoded in the GBL PREPBUFR files (report type 228) but
they are not yet assimilated in any
network. CAP
wind profiler data now encoded in the RUC and RGL PREPBUFR
files (report type 227) but they are not yet assimilated in
any
network.
04/28/2006:
Cooperative Agency Profiler (CAP)
data are no longer available via GTS/BUFR due to the NWS no longer
supporting it. There may be a way to get these data from FSL
(GSD) MADIS in netCDF format.
11/30/2007:
NPN wind profiler surface data no
longer received. These had been decoded into /dcom tank
b000/xx008.
09/15/2008/1500UTC:
Wind profilers coming in in PILOT (PIBAL) bulletins are now
included in the "proflr" dump file and the PREPBUFR file in the RUC
network (report type 229). These data are not assimilated by the
RUC analysis. They will be used by the future (2009)
RapidRefresh system.
10/01/2008:
NOAA Profiler Network (NPN)
wind profiler data (tank b002/xx007 and dump "proflr", used in the
GFS, NAM and RUC analyses), spectral moment data (tank b002/xx010,
not dumped or used by any analyses) and Radio Acoustic Sounding
System (RASS) temperature profile data (tank b002/xx012 and dump
"rassda", used in the RUC analysis, monitored in the GFS and NAM
analyses) obtained from the GTS have been temporarily suspended
for up to 90 days as a result of the need to upgrade these systems to
prevent recently identified IT security threats. The wind profiler
network operates on obsolete equipment that cannot
support necessary IT security methods, and interconnection to
major NWS systems extends the vulnerability to the entire NWS
IT infrastructure. The NPN profiler data (and possible the
other types) will be
available in the same BUFR format from an alternate GSD/MADIS feed
within the next few (3-5) weeks.
10/27/2008:
NOAA Profiler Network (NPN) wind
profiler data (tank b002/xx007 and dump "proflr", used in the GFS, NAM
and RUC analyses), spectral moment data (tank b002/xx010, not dumped or
used by any analyses) and Radio Acoustic Sounding System (RASS)
temperature profile data (tank b002/xx012 and dump "rassda", used in
the RUC analysis, monitored in the GFS and NAM analyses) are now again
available, this time from the alternate GSD/MADIS feed. This is
temporary until the primary NWS feed is restored in approximately two
months. (See 10/01/2008 entry for more information.)
11/25/2008/1500UTC:
Multi-Agency Profiler (MAP) wind and
RASS data [previously called Cooperative Agency Profiler (CAP)] are
once again being decoded into tanks b002/xx011 [MAP profiler
winds, including acoustic sounders (SODARs)] and b002/xx012 (MAP
RASS,
along with NPN RASS), via feed from
GSD MADIS (decoded into BUFR from netCDF format). The MAP winds
are being written into the "proflr" dumps in the NAM/NDAS, GFS/GDAS and
RUC networks. They are included in the PREPBUFR file with report
type 227 in the NAM/NDAS and RUC networks. These are
not monitored or assimilated in any network. The MAP
RASS are being written into the "rassda" dumps and are included in
the PREPBUFR file with report type 126 in the
NAM/NDAS, GFS/GDAS and RUC networks. These are assimilated
in the RUC network and are monitored in the NAM/NDAS and GFS/GDAS
networks.
04/06/2010/1200UTC:
VAD winds generated
from
Level 2 decoder are now encoded
into BUFR tanks
b004/xx017 in /dcom.
These data are not yet dumped in
any NCEP network. Planetary
boundary layer heights generated
from
Level 2 decoder are now encoded
into BUFR tanks
b007/xx021 in /dcom.
These data are not yet dumped in
any NCEP network.
09/13/2011/1400UTC:
The Multi-Agency Profiler (MAP) wind
and RASS decoder was modified to fix a bug in the assignment of height
levels that was introduced back when these data were re-introduced into
the NCEP data processing (via GSD MADIS feed) on 11/25/2008. The
reported heights were assumed to be height above ground and the station
elevation was added to them to obtain height above sea-level. In
reality, the reported heights were already height above sea-level, so
the station elevation was being added to the heights above ground twice.
10/18/2011/1200UTC:
Multi-agency Profiler (MAP) wind
data at
and below 400 mb are now assimilated by the NAM/NDAS GSI. Above
400 mb, these data are monitored by the NAM/NDAS GSI. They had
not even been monitored at any level before, except in the NAM/NDAS
parallel GSI. NOAA Profiler Network (NPN) and
Multi-agency Profiler (MAP) RASS (virtual temperature) data are
now assimilated by the NAM/NDAS GSI. They had been monitored.
05/01/2012/1200UTC:
The RAP (which replaces the RUC
today) assimlates Multi-agency Profiler (MAP) wind
data at
all levels (it also assililates NOAA Profiler Network (NPN)
wind
profiler data just as the RUC did).
03/07/2013/0600UTC:
An upstream BUFR change in
the Japanese and Hong Kong winds on GTS caused NCEP's decoding of
these data (into /dcom database tanks b002/xx013 and b002./xx014,
resp.) to cease. The former was in the ops "proflr" dump and was
being slated for testing in the Global GSI (it was kept out of ops
PREPBUFR files). The NCEP decoder was modified to again process
these on 05/22/2014 however the data were routed to /dcomdev for
testing.
04/08/2014/1200UTC:
VAD winds generated
from
Level 2 decoder are now dumped in the NAM/NDAS network
(included with existing Radar Coded Message VAD winds in "vadwnd"
dump). These are excluded from the NAM/NDAS PREPBUFR files as the
NAM/NDAS GSI is not ready to handle these.
06/24/2014/1200UTC:
MAP wind profilers with more
than 102 levels will now get all levels encoded into the PREPBUFR file
in the NAM, NDAS and RAP networks.
08/12/2014/1200UTC:
VAD winds generated
from
Level 2 decoder are now included in the NAM/NDAS PREPBUFR
files (under report type 224, subtype 2; along with existing Radar
Coded Message VAD winds under report type 224, subtype 1).
These are now assimilated by the NAM/NDAS GSI.
08/30/2014:
Thirty U.S. NOAA Profiler Network
(NPN) sites (including RASS NPN) over the continental U.S. are terminated due to funding
cuts. The NPN network will consist of only 3 Alaskan sites after
today.
08/10/2015/1200UTC:
VAD winds generated
from
Level 2 decoder are now dumped
in the RAP network (included with existing Radar Coded Message VAD
winds in
"vadwnd" dump). These are excluded from the RAP PREPBUFR
files as
the RAP GSI is not ready to handle these.
08/23/2016/1200UTC:
VAD winds generated
from
Level 2 decoder are now included in the RAP PREPBUFR
files (under report type 224, subtype 2; along with existing Radar
Coded Message VAD winds under report type 224, subtype 1).
These are now assimilated by the RAP GSI.
09/13/2017/1430UTC:
The remaining Alaskan NOAA Profiler Network
(NPN) sites (including RASS NPN) have been turned off. This marks the end of the NPN.
/dcom tanks b002/xx007 (NPN wind profiler) and b002/xx010
(NPN wind profiler spectral moments) are no longer created and the
NPN wind profiler data are no longer part of the "proflr" dumps in
the
various networks. Tank b002/xx012 now contains only Multi-Agency
RASS reports and "rassda" dumps in the various networks no longer
contain any NPN RASS reports.
01/07/1988:
Indian radiosonde
(block 42 and 43) mass data are no longer used in the GBL analysis.
06/25/1991/1200UTC:
GBL-SSI implementation resulted in
several changes in data usage in GBL analysis: Significant and
mandatory level data now used. No interpolation of data to
missing levels (RGL analysis still uses special 25 or 50
mb levels with interpolation to missing levels).
Uppermost mandatory pressure level for processing all variables
except moisture changed from 50 to 10 mb. Uppermost mandatory
level below which significant level variables (except moisture) are
processed is 50 mb. Uppermost mandatory pressure level
for processing moisture changed from 300 to 250 mb.
02/10/1992/1800UTC:
CLASS wind data (received from
STORM-FEST field experiment) is now used in the RGL analysis.
These data were not present after 1997 and were also set to no
longer be processed (they they ever became present again) in the RGL
analysis on 02/09/1998/1200UTC.
06/10/1992/1200UTC:
The Complex Quality Control (CQC)
system was implemented (for radiosonde data). It replaced the
"Hydrocheck" program.
08/11/1993/1200UTC:
The uppermost mandatory pressure
level for processing mandatory and significant level data (including
moisture) is changed from 10 mb (mandatory) and 50 mb (significant) and
250 mb (moisture) to 1 mb.
08/28/1995/1200UTC:
Surface mass dropwinsonde data are
no longer used in the GBL analysis (due to quality issues).
10/25/1995/1200UTC:
Indian radiosonde (block 42 and 43)
are now used in the GBL analysis.
05/20/1997/1200UTC:
The radiosonde baseline check in
PREPRO has been turned off. The CQC program already performs a
much more sophisticated baseline check.
06/11/1997/1200UTC:
New NOAA Gulf Stream-IV dropwinsonde
data is
about to become operational. Its specific humidity will not
be used in the RGL or GBL analyses due to quality issues. (Later, on
01/14/1998/1200UTC, the RGL and GBL analyses began using Gulf Stream
dropwinsonde moisture, then even later, on 12/15/1998/1200UTC, the RGL
and GBL analysis again stopped using Gulf Stream dropwinsonde moisture.)
02/09/1998/1200UTC:
RGL-3DVAR implementation
resulted in several changes in data usage in RGL analysis: Data
are no longer interpolated to 25 or 50 mb levels (reported mandatory
and significant levels are used directly). Moisture is no longer
interpolated to levels where it is missing. The uppermost
mandatory pressure level for processing mandatory and
significant level data (including moisture) is changed from 10 mb
(mandatory) and 50 mb (significant) and 250 mb (moisture) to 1 mb.
01/25/1999/1200UTC:
USAF dropwinsonde moisture in no
longer used in the RGL and GBL analyses.
10/02/2000/1200UTC:
The GBL analysis
began using radiosonde and PIBAL balloon drift (location and
time) information.
06/13/2006/1200UTC:
The RGL analysis (changed to GSI
today) is now using radiosonde and PIBAL balloon drift
(location and time) information.
08/22/2006/1200UTC:
NOAA (P-3 and Gulf Stream)
dropwinsonde moisture is now used in the GBL analysis (it is still not
used in the RGL analysis, neither analysis uses USAF dropwinsonde
moisture).
12/04/2007/1200UTC:
NOAA (P-3 and Gulf Stream)
dropwinsonde moisture is now used in the RGL analysis (it had
already been used in the GBL analysis). USAF dropwinsonde
moisture is now used in the RGL and GBL analyses.
08/31/2016:
NOAA Gulfstream-IV is down for
maintenance. It's temporary replacement in operations in NSF-NCAR
Gulfstream-V.
07/19/2017/1200UTC:
Since NOAA Gulfstream-IV is again
available in operations, NSF-NCAR Gulfstream-V is set back to
monitor. NASA Global Hawk temperature and wind is now assimilated in operations (no
longer monitored; moisture is monitored in all networks).
9/20/1988/1200UTC:
Splash-level dropwinsonde reports
are now used in the RGL and GBL analyses.
12/06/1989/1200UTC:
The wind part of splash-level
dropwinsonde reports is no longer processed. Fixed and
moored buoy wind reports with no station pressure are now
processed (on 10/02/1991/1200UTC this
was restricted to only PMEL-ATLAS buoys in the tropical
Pacific).
01/30/1991/1200UTC:
NMC digitized mean sea-level
pressure bogus data no longer used by GBL analysis. (The GBL and
RGL analyses still use the OPC/NOS mean sea-level pressure point bogus,
usually available in NH only).
06/25/1991/1200UTC:
GBL-SSI implementation resulted in
mass data from land SYNOP stations and mass and wind data from C-MAN
platforms now being used in GBL analysis. Mass land SYNOP
data is already being used in RGL analysis.
01/31/1997/1200UTC:
Mean sea-level pressure bogus (PAOBs
in GBL and OPC/NOC point in the RGL and GBL) are no longer used in the
RGL and GBL analyses.
02/09/1998/1200UTC:
RGL-3DVAR implementation
resulted in several changes in data usage in RGL analysis:
Surface land (SYNOP) wind reports are now being used. Surface land
(SYNOP) mass and wind reports within the old LFM grid domain and
without pressure are now being used.
01/09/2001/1200UTC:
METAR mass and wind data are now
assimilated in the RGL analysis.
04/13/2004/1200UTC:
Mobil synoptic land mass and
wind data (ingested into /dcom BUFR tank b000/xx002) included in
"adpsfc" dumps in GBL networks.
01/25/2005/1200UTC:
Mobile synoptic land mass and
wind data used in GBL analyses (not yet used in RGL analysis,
outside of domain anyway).
06/28/2005/1200UTC:
Mesonet mass (surface pressure,
tenmperature, moisture) data are now
assimilated in the RUC analysis (based on "uselist"). METAR
cloud/visibility/weather observations.are now assimilated in the
RGL analysis.
03/31/2008/1200UTC:
Mesonet wind data are now
assimilated in the NAM/NDAS GSI (based on "uselist").
09/15/2008/1500UTC:
SYNOPTIC (both restricted and
unrestricted) surface land data are now included in the
"adpsfc" dump file and the PREPBUFR
file in the RUC network (report types 181/281, 183/284). These
data are now assimilated by the
RUC analysis. They will also be used by the future (2009)
RapidRefresh
system.
09/16/2008/1200UTC:
Roadway data
from numerous mesonet providers (mainly DOT providers) is now
ingested into the applicable /dcom b255 BUFR tanks and
subsequently dumped into the "msonet" dump files and encoded into the
PREPBUFR files in the appropriate networks [dumps in NAM, NDAS, GFS,
GDAS, CDAS, RTMA, RUC and SRUC; PREPBUFR in NAM, NDAS, RTMA, RUC
(upper-air)]. It is not yet used by any NCEP analysis (currently
mesonet data are assimilated only in the NAM, NDAS RUC and RTMA
networks).
11/17/2008/1200UTC:
Mesonet wind data are now
assimilated in the RUC analysis (based on "uselist").
12/16/2008/1500UTC:
The RUC analysis now uses mesonet
mass and wind data only from the site in the "msonet" dump file
closest to the analysis time (when a site appears at more than one time
in the dump file).
06/22/2010/1200UTC:
U.S. (block 70, 72 and 74) synoptic
land mass and wind data are now on the reject list. These data
will not be assimilated by any NCEP analysis. Coincident METARS
at all of these sites provide better surface pressure data.
08/17/2010:
The Australian PAOBs (sea-level
pressure bogus) data are no longer produced after this date.
Empty dumps ("sfcbog") continue to be generated in the CDAS, GDAS
and GFS networks. The CDAS has assimilated these data.
02/08/2011/1400UTC:
U.S. Coast Guard data are now
ingested into /dcom tank b001/xx007. These are not yet included
in any dumps.
10/18/2011/1200UTC:
Mesonet mass (surface pressure,
tenmperature, moisture) data are now assimilated by NAM/NDAS GSI
(subject to both a static "uselist", and a dynamic reject list
constructed from RTMA - these lists also now apply to mesonet wind data
which had been used prior to this) with one exception (see below).
The mesonet mass
data had been monitored.
Exception: Surface pressure is not
assimilated at sites where both it and altimeter setting are
missing, in which case surface pressure is estimated from
U.S. Standard Atmosphere mean sea-level pressure (mean sea-level
pressure is always missing for mesonet reports) and reported
temperature and elevation (these sites have an "x" in character 8
of report id).
02/14/2012/1200UTC:
The "sfcshp" dumps in all networks
now include U.S. Coast Guard reports (from /dcom tank b001/xx007).
These data are not yet read by the PREPBUFR processing and thus
are not assimilated by any analysis. The CDAS, GDAS and GFS
networks no longer attempt to dump Australian PAOB (sea-level
pressure bogus) data ("sfcbog"). These data have not been
produced since 08/17/2010.
03/29/2012/1200UTC:
TAO refresh buoys are now decoded
into the /dcom BUFR database in tank b001/xx002.
06/05/2012/1400UTC:
Unrestricted surface ship reports
are now encoded into new /dcom tank b001/xx013. (Restricted
surface ship reports remain in /dcom tank b001/xx001.) These
unrestricted ship reports are now dumped in all networks as part of the
"sfcshp" dump. A new duplicate-checking program, BUFR_DUPSHP,
compares reports in tanks b001/xx001 and b001/xx013 are removes all
duplicates. The reports in b001/xx001 are retained when such
duplicates are present. Most of the reports in b001/xx013
duplicate those in b001/xx001. The unrestricted ship reports
making it out of the dump duplicate check are read by the PREPBUFR
processing and are assimilated into all analyses that use surface
marine reports.
07/31/2012/1200UTC:
Mesonet "Climate Reference Network"
data are now ingested into /dcom tank b255/xx111. These are not
yet included
in any dumps.
06/24/2014/1200UTC:
The U.S. Coast Guard reports
(from /dcom tank b001/xx007 and included in "sfcshp" dumps in
all networks) are now read by the PREPBUFR processing and
encoded as report type 180/280 in the PREPBUFR files when surface
pressure information is available. These will now be assimilated by all
analyses.
06/24/2014/1200UTC:
Surface reports with missing
pressure will now be stored in report types 192/292 (SYNOP), 193/293
(METAR), 194/294 (marine) and 195/295 (msonet) in
NAM, NDAS, RAP, RTMA and URMA PREPBUFR files (these
include U.S. Coast Guard reports with missing pressure in
report types 194/294). These are not assimilated by any
analysis.
08/12/2014/1200UTC:
The NAM/NDAS GSI now
assimilates
surface observations which lack a pressure report.
09/11/2014/1800UTC:
The RTMA and URMA GSI now assimilate
surface observations which lack a pressure report.
08/10/2015/1200UTC:
Surface marine reports
previously, incorrectly deemed over land and flagged will now be deemed
over water and be available for assimilation in every network.
08/23/2016/1200UTC:
Mesonet mass and wind data are now
assimilated in the RAP GSI (assumed they are based
on "uselist"). METAR cloud ceiling height (derived from
cloud amount and cloud height) is now assimilated by RTMA and URMA GSI.
11/17/2016/1315UTC:
BUFR-feed drifting and moored buoys
now ingested into /dcom database tanks b001/xx102 and b001/xx103, resp.
These data are not yet dumped in any network. However, as a
result of the 11/01/2016 termination of 90% of the data in
TAC-fed FM 18 buoy tank b001/xx002 (which is a part of
the "sfcshp" dump), a temporary workaround has been
implemented. This workaround remaps affected reports in bulletin originators LFPW, LFVW and KARS from
b001/xx102 and b001/xx103 tanks to b001/xx002 tank to
allow these reports to continue to be dumped and assimilated.
Once we are ready to handle the BUFR-feed buoys in tanks
b001/xx102 and b001/xx103, this workaround will be removed.
10/11/2017/1230UTC:
Mesonet "Urbanet"
data are now ingested into /dcom tank b255/xx031. These are not
yet included
in the "msonet" dumps. Mesonet visibility data are now ingested
for all networks and are included in the "msonet" dumps (for those
types inclded in the dump) however, due to issues in data quality,
visibility is not assimilated by any network.
12/13/2017/1400UTC:
In the URMA network, the new
GLERL-adjustment processing (PREPOBS_GLERLADJ) begins running
for selected surface reports in the Great Lakes region as
part of the PREPBUFR processing. Click here for more information.
02/12/2018/1500UTC:
Bulletin originators KWBC and CWAO
added to list for which BUFR-feed drifting and moored buoys can be
remapped into legacy TAC tanks in /dcom. See 11/17/2016/1315UTC
change above for more information.
V. WSR-88D (NEXRAD and TAIL-DOPPLER) RADAR
6/17/2008/1200UTC:
Update to the ingest package.
Radial wind quality control significantly upgraded. New
reflectivity quality control added. Reflectivity Single
Radar Coordinate (SRC) flat-files are now generated for the
(yet-to-be-implemented) radar reflectivity mosaic processing package to
pick up.
6/17/2008:
Nearly 90 of the 135 NEXRAD sites
over the CONUS have now switched from Build 8 to Build 10 software.
We are still unable to ingest these Build 10 sites, so we are
losing ~67% of the Level 2 (and possibly also Level 2.5) radar
data.
09/15/2008/1500UTC:
Level 3 and
Level 2.5 NEXRAD radial wind data are now dumped ("radwnd") in
the RUC network. These data are not assimilated by the RUC
analysis. They will be used by the future RapidRefresh
system.
09/15/2008:
All 135 NEXRAD sites
over the CONUS have now switched from Build 8 to Build 10 software.
We are now unable to ingest any Level 2 radial wind and
reflectivity data from these Build 10 sites. Level 2.5 and 3
radial wind data are not affected.
10/07/2008/1500UTC:
We are now again able to ingest
Level 2 radial wind and reflectivity data from all 135(?) NEXRAD sites
with the implementation of the "supres" ingest code which reads Build
10 and transforms it back into pseudo-Build 8 before ingesting it into
/dcom. These data are again dumped into "nexrad" files in the NAM
and NDAS networks and are again being assimilated by the NAM/NDAS GSI.
11/17/2008/1200UTC:
The RUC analysis now processes three-dimensional
Level 2 radar reflectivity mosaic data which produces a latent heat
specification to be used in the model digital filter.
04/06/2010/1200UTC:
New Level 2 ingest and QC bundle implemeted.
Improved QC and processes Build 10.
07/27/2010/1200UTC:
Two additional hourly ingest job
runs have been added for the Level 2 and Level 2.5 NEXRAD
radial wind data. These new run times are at 22- and 50-minutes
past the hour. The ingest now runs four times per hour (the
previous run times at 5- and 35-minutes past the hour
remain). With this change, most of the hourly Level 2.5 data
centered on the hour are now ingested at 50-minutes past the hour
rather than at 5-minutes past the next hour. This allows the
late-cutoff 00 and 12Z RapidRefresh dumps to now see the full
complemement of Level 2.5 data (before they saw little, if any, Level
2.5 data; they still do not see any Level 2.5 data at the other
hours which have an early-cutoff dump time). The hourly
Level 3 data continue (usually) to be ingested at 35-minutes past the
hour.
10/18/2011/1200UTC:
Level 2.5 NEXRAD radial wind data
are now used ONLY over Alaska by the NAM/NDAS GSI.
(Level 2 radial winds, which are used over the CONUS, are
not available over Alaska.)
11/20/2012/1200UTC:
Canadian radar data are now
ingested into /dcom. Data include reflectivity (each hour,
centered on 00-23z, encoded into tanks b006/xx080 through xx103,
resp.) and radial wind (each hour, centered on
00-23z, encoded into tanks b006/xx110 through xx133, resp.).
These are not yet included
in any dumps.
11/20/2012/1200UTC:
P-3 aircraft Tail Doppler Radar
(TDR) radial wind data are now
ingested into /dcom tank b006/xx070.
These are not yet included
in any dumps (with the exception of HWRF).
10/04/2013/1200YTC:
P-3 aircraft Tail Doppler Radar
(TDR) radial wind data assimilated for the first time in the
production HWRF system.
08/23/2016/1200UTC:
Level 2, 2.5(?) and 3(?)
NEXRAD radial wind data are now assimilated by the RAP GSI.
08/23/2017/1200UTC:
Level 3 and
Level 2.5 NEXRAD radial wind data are no longer assimilated by the NAM and RAP GSI. The
Radar Operation Center is going to remove the WSR-88D super-ob product
(Level 2.5 and Level 3 radial wind) in the near future. The Level 2.5
and Level3 radial winds had been used only in the Alaska domain
due to there being no Level 2 data available before 2016. The change
will have no impact on CONUS domain.
NOTE: Find out if L2 radar reflectivity is assimilated in NAM!! (and if so when?)
12/02/2008/1500UTC:
Lightning data from Vaisala's National
Lightning Detection Network (NLDN - short range) and Long-range
Lightning Detection Network (LLDN)
are now ingestred into /dcom database tanks b007/xx001 and
b007/xx002, resp. These data are not yet dumped in any network.
12/15/2009/1200UTC:
The GFS/GDAS GSI now assimilates
tropical storm pseudo sea-level pressure observations using information
in the Q.C.'d tcvitals files. These get a report type of 112 and are
written to the post-analysis PREPBUFR files.
10/18/2011/1200UTC:
The t-12 NDAS now starts from a
global sigma first guess which reflects the relocation of tropical
systems (if any are present).
02/14/2012/1200UTC:
The CDAS, GDAS and GFS networks
now dump the following oceanographic data types: "bathy" [eXpendable
BathyThermographs (XBT) and thermistor chain moorings {via GTS,
originating from WMO FM-63 (BATHY) format}], "tesac"
[Conductivity-Temperature-Depth (CTD) probes, Argo profiling floats,
moorings {via GTS, originating from WMO FM-64 (TESAC)
format}], and "trakob" [ThermoSalinoGraphs (TSG) {via GTS, originating from WMO FM-62 (TRACKOB) format}].
These data are not assimilated by any atmospheric analyses.
05/01/2012/1200UTC:
Lightning data from
Vaisala's Long-range
Lightning Detection Network (LLDN) and National
Lightning Detection Network (NLDN - short range) are now dumped
by the RAP ("lghtng"). These data are not yet assimilated.
09/08/2011:
Lightning data from the Long-range
Lightning Detection Network (LLDN) from Vaisala stopped. It
later resumed on 07/17/2013.
02/25/2014:
Lightning data from
Vaisala's Long-range
Lightning Detection Network (LLDN) and National
Lightning Detection Network (NLDN - short range) are assimilated
by the RAP GSI.
10/07/2014/1200UTC:
BUFR-feed marine subsurface data, currently only in the form of glider data, now decoded into BUFR tank
b031/xx005. These data are not assimilated by any atmospheric analyses.
11/12/2015:
Vaisala lightning data now
encrypted. Lightning data from Earth
Networks, Inc. (ENI) Total Lightning Network (ENTLN) are
now ingestred into /dcom database tank b007/xx003. These
data are not yet dumped in any network.
03/21/2017/1200UTC:
Lightning data from
Vaisala's Long-range
Lightning Detection Network (LLDN) and National
Lightning Detection Network (NLDN - short range) are now dumped
by the NAM ("lghtng") and are assimilated by the NAM GSI.
12/13/2017/1330UTC
Airborne
eXpendable BathyThermograph (AXBT) data now decoded into BUFR tank
b031/xx004. These data are normally generated only during
certain NOAA hurricane hunter flights and other special sea-based
reconnaissance missions.
03/21/2017/1200UTC:
Synthetic mass and wind bogus data in the
vicinity of tropical cyclones no longer generated in NAM
(SYNDAT_SYNDATA program no longer runs).
07/19/2018/1200UTC:
The GFS/GDAS GSI no longer assimilates synthetic wind bogus profiles constructed in the
vicinity of tropical cyclones by program
SYNDAT_SYNDATA (PREPBUFR report type 210). These are monitored by
the GFS/GDAS GSI but may eventually be shut off.
