Changes to the operational FVS database:
- Upgraded HIRESW verifcation to conform to July 2014 HIRESW upgrade:
- AKNMM renamed AKNMMB
- HINMM renamed HINMMB
- PRNMM renamed PRNMMB
- EASTNMM renamed EASTCONUSNMMB
- EASTARW renamed EASTCONUSARW
- WESTNMM renamed WESTCONUSNMMB
- WESTARW renamed WESTCONUSARW
- Added CONUSNMMB, CONUSARW
- All NAM*HW verification files (NAM verified over the Hiresw domains) were turned off
- A correction to the calculation of cloud base heights - the model terrain height is subtracted from the forecast cloud height
to compare to observed values in geometric height AGL.
- Addition of several variables (including 0-6 km wind shear, Brooks-Craven Severe Parameter, and 80-m winds, Haines Index,
Ventilation rate, Surface CAPE)
- Addition of RAP grid 130 to the operational verification suite.
- Added Hawaii (hirtma), Alaska (akrtma), Puerto Rico (prrtma) RTMA
- Added 2.5 km CONUS DNG (smartconus2p5) and 3 km Alaska DNG (smartak3)
- Added 2.5 km URMA (urma2p5) and NARRE
- Verification of aircraft temperatures/winds for most models/grids was inadvertently turned off and will be reinstated at
a later date.
Changes to the operational FVS database as part of SREF implementation:
- All Eta and RSM members dropped, replaced by additional WRF-NMM/ARW members and NEMS-NMMB members
- WRF-ARW: srarwctl, srarwn1, srarwn2, srarwn3, srarwp1, srarwp2, srarwp3
- WRF-NMM: srnmmctl, srnmmn1, srnmmn2, srnmmn3, srnmmp1, srnmmp2, srnmmp3
- NEMS-NMMB: srnmbctl, srnmbn1, srnmbn2, srnmbn3, srnmbp1, srnmbp2, srnmbp3
Changes to the operational FVS database:
- Rapid Update Cycle (RUC), replaced with Rapid Refresh (RAP), all "ruc" vsbd files
now named "rap"
- Add verification of Best (most unstable) CAPE
- Verifiction of CAPE for NAM/GFS now using field computed from virtual temperature
- Mesonet observations (MSONET) now separated from other surface data (ONLYSF)
- Obsolete ANYSFC verification type removed
- Big fixes:
- Restore verification of grids over Hawaii
- Fixed bug from 10/18/2011 package: on 10/18/11, code was changed to do the
model-to-ob location interpolation using nearest neighbor instead of lower left corner.
Changes to the operational FVS database in conjunction with the 18 October 2011 NAM implementation:
- Added the new NAM nested runs (0-60 h)
- 4 km CONUS
- 6 km Alaska
- 3 km Hawaii
- 3 km Puerto Rico
- Placeable fire weather nest (1.33 km if over CONUS; 1.5 km if over Alaska, 0-36 h)
- Added verifications of the NAM and RUC over the fire weather nest domain
- Changed most model FVS jobs to process 20 pressure levels (up to
50 mb) instead of 19. To compute 50 mb verification stats, the prepfits code was extrapolating pressure level data at 100 mb up to
50 mb, causing spurious 50 mb verification numbers.
- Fixes to code errors relating to visibility, CAPE, and PBL.
Code fix in parallel NAM verifications to allow for consistent ob counts for surface dewpoint verifications
between all models; previously, higher resolution grids had higher ob counts, leading
to inconsistent verification between the parallel 12 km NAM parent run and the nested runs.
The problem will be fixed in the operational NAM verification at a later date.
Changed all parallel NAM (including nests) jobs to process 20 pressure levels (up to
50 mb) instead of 19; prepfits code was extrapolating pressure level data at 100 mb up to
50 mb, causing spurious 50 mb verification stats. The problem will be fixed in the operational
NAM verification at a later date.
RUC verification extended to 18-h; this was accidently turned off in the 4/6/2010
||J. Zhu, Rogers, Shafran
Changes to the operational FVS database:
- A fix to the mismatch of the start hours for the NAMHW. This is the verification
for the NAM model on specific regions to be compared with the HIRESW model. Since in the
operational HIRESW runs, a certain domain or region only runs at certain cycle(s) of the
date (for example, the "east" domain runs at 00 and 12z only, "west" at 06z and "alaska"
at 18z), we will have to read in the input hours for the NAMHW verification to be same
as for the HIRESW.
- A change to verify the HIRESW on 5km grid (currently it's doing the 8km grid).
- Add the verification for GFSE. This is the verification for the GFS model from
90-192 hours for the comparison with the DGEX. Add verifications on the DGEX and GEFS for the
Alaska area and change to verify both models every 6 hours (current production is every 12 hours).
- Add the verification for the RUC First Guess.
- Add the verification for the NAM smartinit grids.
- Add 2 new variables to the verification codes: the Richardson number PBL and
the mixed-layer height. The original PBL is the TKE-based PBL.
- Rename the model name of the RTMA inside the vsdb files from "RTM" to "RTMA"
to be consistent with the model name in the file directory.
- Change the directory name for the RSM from "rsm" to "rsmh", which stands for "RSM Hawaii" region.
- Consolidate the gridtobs input parameter files among the NAM, NDAS, RUC, NAMHW, HIRESW,
SMARTINIT and SREF models.
- Consolidate the gridtobs-e input parameter files among SREFENS and SREFENSX
- A fix to the subroutine getbak.f (in PREPFITS) to output the Relative Humidity
(RH) verification on pressure levels for the GDAS and RUC models, and any other future model
grid that does not output specific humidity on pressure levels.
- Change to use NDAS prepbufr files for all the models (except for the AQM)
for data input consistency in the verification.
- Change the thresholds for verification on Visibility and Cloud-base Height.
- Changes are being made to all the non-aqm verification codes to ensure cleaner,
more graceful exits in times of job stoppages, for whatever reason, using the w3 lib routine
ERREXIT rather than STOP or ABORT.
- Verification of 15-h and 18-h RUC forecasts were inadvertently turned off when this package was
RUC forecast extended from 12 to 18-h; RUC verification extended to 18-h as of this date.

New database (/mmb/wd20er/data/vsdb_aux) on tempest which contains FVS records of additional fields added by
P. Shafran over the years (not all of these are available for all models):
- E. Rogers' FVS jobs on the CCS turned off, start use of VSDB files produced in operations

- NGM turned off
- Bias-corrected SREF ensemble mean forecast (SRMEANX) temporarily turned off pending script fix in SREF
- Added verification of specific humidity on pressure levels
- Added verification of GFS 1-deg lat/lon output
- Operational NAM VSDB file is split into "NAM40" (upper air verification using 40 km grids #212 and #216)
and "NAM" (upper air and surface verification using 12 km grids #218 and #242) to provide continuity
with E. Rogers' datebase and to allow FVS to run faster on tempest
- FVS records in NAM, GFS, and all SREF members VSDB files of new fields are extracted from
monolithic VSDB files and put into a new database (see below)

Changes/additions to FVS model names:

- "ETA" discontinued, added "NAM40", which is the operational NAM verified against all upper air data
using the 40 km grid #212 over the CONUS and 45 km grid #216 over Alaska. All previous on-line "ETA" FVS files
were renamed and copied to the "NAM40" directory.

- Hawaii HIRESW : old=hi10 ; new = hihw
- Puerto Rico HIRESW : old=pr10 ; new = prhw
Corrected error in PREPFITS : Code set the default GRIB bitmap to 1, so that any model
whose verification grid had a GRIB bitmap=0 would attempt to verify data in the regions
outside of the model integration domain where the bitmap=0
Added verification of surface METAR data (PREPBUFR obs types 187/287) for all models.
