Hi Aaron,
Is the grib2 file you attached intended as a single-record example or is it the
full file you are producing?
I ask because the only record shown by wgrib2 is:
> wgrib2 -v2 test.grib2
1:0:01Z14oct2009:BREF Base Reflectivity [dB]:lvl1=(255,missing)
lvl2=(255,missing):no_level::
and after adding TAMU to wmocenter.tbl (center ID 199) I see "No GRIB record
was found" error messages both with dcgrib2 and nagrib2.
