Brian,

I have looked at the NWS MD division GRIB2 decoder but I haven't looked at
the FSL one. Do you know who's the contact?  The GRIB2 decoders that I
wrote is in java and it's going to interface with a netcdf package written
in java. The only part to do is to connect the two API's .  At this time,
it shouldn't be hard for "regular" type gribs, it going to be more work
for the ensembles and the stitched together grids.

Robb...
