Robb,
I have been using the gribtonc decoder to decode NOGAPS model output
and view the data on AWIPS, the deocder works great! I recently tried
to add some fields from the NOGAPS, but the decoder says that they are
oversized GRIb product. The grid size has not changed still 360x181,
but I noticed that the file sizes go from 81 Kb to 187 Kb. When I try
to run the gribdump on these larger files nothing happens. I used
wgrib on these files and only thing I can find is that the number of
bits for the larger files is 20 instead of 10 on the smaller. So my
question is there something I need to change to make it work. What are
your thoughts?
Thanks in advance.

Jason,
We just ran into this problem recently, I plan to make a decoders release
soon. The actual problem is that the grid sizes have increase and
gribtonc doesn't have enough space to hold the increased size. It's an
easy fix;
It's only a one word modification in grib1.h, change:
#define MAX_GRIB_SIZE 20000
to
#define MAX_GRIB_SIZE 100000
That's all, then:
% make clean
% make
That should do the trick.
