UPP Online Tutorial for UPPV4.1 | Setup and Run > itag

The itag is read in by unipost and is generated automatically in the run_unipost script based on user-defined options in the user edit section. The itag contains the following 5 (7) lines for processing WRF (FV3) data:

1. Path and name of the WRF (FV3 dyn*) output file to be post-processed.
2. Format of the WRF (FV3) model output (netcdf or binarynemsiompiio).
3. Format of the UPP output (GRIB1 or GRIB2).
4. Forecast valid time (not model start time) in YYYY-MM-DD_HH:MM:SS format (i.e. the forecast time desired to be post-processed).
5. Dynamic core used (NCAR or GFS).
6. FV3 only: Path and name of the FV3 phy* output file to be post-processed.
7. FV3 only: Name of the Grib2 control file (postxconfig-NT-GFS.txt)
