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:
- Path and name of the WRF (FV3 dyn*) output file to be post-processed.
- Format of the WRF (FV3) model output (netcdf or binarynemsiompiio).
- Format of the UPP output (GRIB1 or GRIB2).
- 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).
- Dynamic core used (NCAR or GFS).
- FV3 only: Path and name of the FV3 phy* output file to be post-processed.
- FV3 only: Name of the Grib2 control file (postxconfig-NT-GFS.txt)
