Hello,
I am trying to use GEFSv12 reforecast data (available at https://noaa-gefs-retrospective.s3.amazonaws.com/index.html) to drive a regional simulation in WRF. I have pre-processed the grib files such that the required fields are contained in one file per forecast hour. Also, note that the fields vary in spatial resolution (0.25-deg at pressure levels below 700mb, else 0.50-deg), but I did not regrid them to a common resolution since grid can be defined per variable per level in the intermediate file.
I used Python package pygrib to read the grib data, and pywinter to write the corresponding intermediate files. I compared the results of the rd_intermediate.exe to results using intermediate files generated by ungrib. Upon running metgrid.exe, I encountered an error during the output module part:
What might be causing this error? Should I regrid the 0.25-deg fields to 0.50-deg first for homogeneity?
