Global parallel initialization using FV3 data #33

Closed GeorgeGayno-NOAA closed 4 years ago

GeorgeGayno-NOAA commented 4 years ago

Users are asking how to coldstart a full global parallel (80 enkf members and the high res member) using FV3GFS GDAS data. The only GDAS data available in HPSS is tiled restart files. Therefore, the fv3gfs_chgres.sh script, which runs the old serial chgres, will not work. Need to come up with a replacement to that script that uses chgres_cube. The script could also be designed for users who only want to run a free forecast.

Dusan opened #69 to fix a compilation problem with the public release version of chgres_cube. Will add his fix under this issue.

On Cray, I made my own copy of Dusan's wgrib2 api, then updated the chgres_cube build module to point to it. Branch updated at c4914d3. Not really part of this ticket, but added for convenience.

Kate and I tested the GDAS initialization scripts on Hera, Dell and Cray for numerous cases between May 21, 2012 and Feb 26, 2020. We are satisfied they are working. We decided to add GFS v16 capability later, when the contents of the v16 tarballs are finalized.

I ran the chgres_cube regression tests on Jet, Hera, Cray and Dell. All tests passed as expected.

Will merge to 'develop'.
