     Robb,
     Sorry about all of the questions
I am now trying to decode the Navy's NOGAPS model data supplied in GRIB into netcdf format. 
Jason,

Contact Navy's NOGAPS people to see what they use to read there own grib
files. Also try to find out what is the model structure of NOGAPS. I
believe that gribtonc will have to be modified to translate these type of
grids.
When I tried to use gribdump -h or grib -b, I
get nothing. When I use gribdump -v on the file I get messages like the following saying: 
     oversize GRIB product
     error reading GRIB product
     It exits saying 0 WMO Msgs, 0 GRIBs decoded, 0 written
is this because the the nogaps is not described anywhere in the program? What do I need to do to get it to work? The data is on a standard grid, I think 207. Thanks for all of your help, and sorry to take your time. 


In file gdes.c at 1356 there is a definition for grid 207, does this match
the params of the raw file. At this point a debugger would surely pinpoint
the problem.  The gribtonc program is tailored to FOS/NOAAport types of
products, it's not a general translator. 

Here's a url to another grib reader, maybe it will work better:
