Subject: Re: 20050414: IDV - Error reading GRIB file

The gribsimp program is part of the MEL package:

https://mel.dmso.mil/mel_tools/grib.jsp

I wonder if using 'cat' to glue them together is the problem. Do you
know which grid is bad [or the one before?]. I think the 43rd grid is a
400mb temperature....
