Re: 20050406:CODIAC grib-gempak problems



Jeff,

You should definitely be using dcgrib2 for all decoding!!! 

Since I don't see any output from the first 2 entries, it would
appear that there is nothing found in the file that looks like a GRIB
entry that would cause the decoder to open the appropriate tables.

So, I'd suggest looking at the files in question...and did I mention,
using dcgrib2?!
