MPAS applications: issues with absolute vorticity and latent-heat flux fields

[jaymes-kenyon]

(1) The GRIB2 fields of "ABSV" (absolute vorticity) on isobaric surfaces are problematic when using UPP on HFIP–MPAS output. For these ABSV fields:

• A 1-DX "ring" of noisy values is present, and
• values are entirely zero within this ring.

The presence of missing values surrounding the computational domain is the underlying reason for this problem. To fix the issue, the calculations for obtaining wind at mass points ("UH" and "VH") should first check for "SPVAL".

(2) Additionally, the surface latent-heat flux currently reads-in from a netCDF array called "QFX". However, for current MPAS applications in RRFS and HFIP, this array is actually named "LH."
