2. Code OverviewΒΆ
The UPP can be used to post-process WRF-ARW, WRF-NMM, NMMB, GFS, CFS, and FV3 forecasts with current support within UFS applications available for FV3 only. It can ingest FV3 write component files in netCDF and binarynemsiompiio format.
UPP Functionalities:
Interpolates the forecasts from the models native vertical coordinate to NWS standard output levels (e.g., pressure, height) and computes mean sea level pressure. If the requested parameter is on a models native level, then no vertical interpolation is performed.
Computes diagnostic output quantities (e.g., convective available potential energy, helicity, relative humidity). A full list of fields that can be generated by the UPP is provided in GRIB2 Fields Produced by UPP.
Outputs the results in NWS and WMO standard GRIB2 format (see Grib documentation).
