Recent Releases of global-workflow

global-workflow - GFSv16.3.23 - AFWA global snow, GOES-19, wave point optimization, and bufr station updates

RFC 13833 - AFWA global snow, GOES-19, wave point optimization, and bufr station updates

WHAT the changes are:

  1. Add 121 new stations to the GFS BUFR sounding output and correct the location of three existing stations;
  2. Use the new AFWA global snow field instead of legacy hemispheric snow fields;
  3. Update the GSI code to read Saildrone observations;
  4. Update the GSI global_convinfo.txt fix file to allow assimilation of GOES-19 AMVs (Atmospheric Motion Vectors) and monitor Saildrone data;
  5. Restructure the logic to generate wave point output.

WHY this changes are being made:

  1. New stations are added per request of users;
  2. The new global snow file replaces legacy hemispheric files due to be retired;
  3. The GSI code is updated to prepare for new data source;
  4. The convinfo (conventional data information) file is updated to prepare for transition of the GOES-19 satellite to GOES-East operations and to monitor Saildrone data when available;
  5. The wave post point processing change improves efficiency.

Implemented on March 25 during the 12Z cycle.

global-workflow - GFSv16.3.21 - WAFS removal from GFS

RFC 13621 - WAFS removal from GFS

On WCOSS2, implement WAFS (World Area Forecast System) v7.0.1 into operations by removing the evaluation flag and turning on production DBnet alerts. This implementation is a separation of the WAFS component from the GFSv16 application. There is no science change. This will allow for easier future updates of the WAFS since it will no longer be embedded in the GFS.

Also included in this upgrade:

  • improvements to the enkfgdas_update job resource and environment settings
  • a fix for the syndat_getjtbul code when parsing 3-character storm names

Implemented on January 29 during the 12Z cycle.

global-workflow - GFSv16.3.19 - place PlanetiQ RO data in monitor mode

RFC 13303 - place PlanetiQ RO data in monitor mode

On WCOSS2, upgraded the GFS to v16.3.19. The reason for this change is the following: provider PlanetiQ offers two versions of their data: basic and premium. Premium is high quality data. Basic is a degraded version of the premium data. EMC learned last week that NESDIS purchased the basic (degraded) data. This ARFC prevents the GFS from assimilating the degraded PlanetiQ GPS Radio Occultation (GPS-RO) data when it flows into the GFS. This update also increased the walltime limit for the jenkfgdas_update job from 30 min to 40 min to address runtime variation.

Implemented on September 30 from 1330Z to 1615Z.

This is a re-release of the prior GFSv16.3.16 version. This update corrects a missed prepobs version change for developer run mode. The operational GFS was unaffected since it does not directly reference the prepobs package in operations (the upstream obsproc system does). The prepobs package also updated in operations alongside the obsproc/v1.2 upgrade with prepobs now being v1.1.0.

The objective of this new job is to:

  • support the WMO Integrated Global Observing System (WIGOS) WDQMS project
  • ensure that WMO observational data and products are reliable and correspond to agreed-upon needs
  • 6-hourly summaries include surface (synop), upper-air, and surface marine (ship and buoy) observations

Was to be implemented on June 26, 1400Z to 1900Z; postponed due to College Park hardware issues; was implemented July 2, 1400Z to 2000Z.

RTOFS v2.3.0 accounts for bug fixes, bias corrections, and changes in data inputs for operations. The initialization scheme for the previous version of RTOFS creates an initialization shock, spurious waves, and systematic errors in the prediction of the ocean state in the equatorial ocean.

global-workflow - GFSv16.1.3

RFC 8691 - On WCOSS, turned off IASI (Infrared Atmospheric Sounding Interferometer) on Metop-A in multiple models' ‘satinfo.txt’ files. This was done because IASI on Metop-A has been significantly degraded since September 17. Since the instrument is being decommissioned next month, NCO permanently removed this instrument from assimilation.

global-workflow - GFSv16.1.2

Update in operations to address two issues:

RFC 8260 - On WCOSS, placed CrIS NPP channels in monitor mode for the GFS, HRRR, HWRF, and RAP models. This was done to minimize possible degraded analyses due to the CrIS NPP data anomaly/outage that began on May 21, 2021. Implemented on May 28 at 1145Z.

RFC 8313 - Upgrade the GFS to v16.1.2, which includes the following two fixes:

  • an updated UPP GTG subroutine to increase
    • wind threshold to 500 m/s,
    • height threshold to 1.0E7 m, and
    • temperature threshold to 3000 K.
      Also instead of aborting, only send out “out of bound” warning messages when thresholds are exceeded.
  • an updated GFS post processing script so that the GFS post-processing job will not crash and the generation of GFS pgb files will continue even if the WAFS fails.

These changes address recent failures of the GFS WAFS post-processing job which produce turbulence products, which then caused the generation of GFS pgb files and downstream products to come to a halt.

RFC 8196 - On WCOSS, implement the GFS v16.1.1 upgrade to begin assimilating GPS radio occultation (GPS-RO) data from GeoOptics for all forecasts as long as the data are available. This upgrade also addresses several bugs from v16.0.0:

  • 2021 tropical storm update
  • Fixes the calculation of the layer height increment
  • Includes RW-NH* boundary points in the wave component
  • Fixes the East Pacific wave grid interpolation to include all American Samoa islands
  • Unmasks the Gulf of California, Red Sea and Persian Gulf in 0p25 global interpolated wave output grids
  • Fixes a bitmask issue in 0p25 deg blended WAFS icing and turbulence products below 500 hPa.

Implemented May 20 2021 at 12z.

global-workflow - GFSv16.0.9

GFS version 16.0 is the first major upgrade to Finite Volume Cubed Sphere (FV3) dynamical core based GFS which replaced the spectral dynamical core in June 2019. In this upgrade, the number of model vertical layers is increased from 64 to 127 and the model top is extended from the upper stratosphere (~55 km height) to the mesopause (~80 km height). With this upgrade, for the first time, the operational stand alone global deterministic WAVEWATCH III based wave model Multi_1 (wave_multi_1.v3.3) is merged into the GFS system. The WAVEWATCH III model is updated and coupled to the GFS using a one-way coupling scheme where the atmospheric model provides forcing to the wave model using the NOAA Environmental Modeling System (NEMS). Major changes have also been made in other components of the forecast system including model physics, data assimilation, system infrastructure, post-processing and product generation.

Merged final GFSv16 (v16.0.9) package into operations branch. GFSv16.0.7 system implemented March 22nd 2021 @ 12z. Follow-up updates/fixes resulting in v16.0.8 (~March 31st) and v16.0.9 (April 27th 12z) were implemented.

global-workflow - GFSv15.3.5

The GFS was updated in operations to v15.3.5. The versions of the gempak and bufr libraries were updated ahead of a January 1st 2021 bug.

(Note - v15.3.4 tag was skipped since updates in ops for that were to fix files that are external to GFS system (new 2021 CO2 files). The v15.3.4 system is otherwise identical to the v15.3.3 system tag.)
