Solution

These two interfaces can be unified.

The changes will be made in both ufs-weather-model repository and fv3atm repository:

• fv3atm:

  1. Unified inline post interface post_fv3
  2. Add bug fix for dx/dy computation
  3. Add reading pwat from FV3
  4. Clean up some legacy variable initialization.
  5. Read max/min 2m T from tmax_max2m for GFS, and from t02max/min for RRFS and HAFS.
  6. Read 3D cloud fraction from cld_amt for GFDL MP, and cldfra for other MPs.
  7. Add a new namelist model_inputs in itag for input modelname, e.g. GFS, FV3R.
  8. Update upp revision to c939eae

• ufs-weather-model:

  1. Update post_itag, post_itag_fv3lam and post_itag_hafs under tests/parm with modelname input
  2. Update all diag tables under tests/parm/diag_table to replace pwatclm with pwat

The changed results above tests come from:

• sfcf*, phyf*: output variable name change from pwatclm to pwat
• UPP outputs in GRIB2 for GFS: output pwat from model calculation instead of UPP calculation
  891:51910349:PWAT:entire atmosphere (considered as a single layer):rpn_corr=0.999814:rpn_rms=0.357892
• UPP outputs in GRIB2 for regional FV3 (RRFS, HAFS): a bug fix in ABSV, MCONV calculation in UPP; pwat update
