NetCDF to Intermediate File

[bigveech]

Hello,
I'm trying to convert a NetCDF file (specifically gfs.tCCz.atm(anl|fFFF).nc files described here NCEP Data Products GFS and GDAS) into a WPS intermediate file.

Are there any resources detailing the structure of WPS intermediate files or any off the shelf programs that can help me convert these files?

you could use ungrib geogrid metgrid to use the gfs data for wrf

here's some tutorials:

The issue is that these files are NetCDF, not grib. I don't think ungrib works with NetCDF files unless I'm missing something

@bigveech
You are right that ungrib cannot process netCDF data.
Please take a look at the document here, which describes in detail the format of intermediate data. A small piece of code is also provided, which can be used to output data in this specific format.
