[gradsusr] GRIB-1/GrADS Diagnosis

[Perry, Aaron]

Hi All,


I'm currently having an issue with getting GRIB-1 data to be processed in GrADS. I'm using archived 12km NAM data from the NCDC NOMADS Server. I get the "Constant field.  Value = 0" error...


Below is the control file that I've created using grib2ctl:


dset /mnt/homes/perrya/jaycasestudy/data/nam/nam12.2014120700.%f3.grb
index /mnt/homes/perrya/jaycasestudy/data/nam/nam12.2014120700.000.grb.idx
undef 9.999E+20

What am I doing wrong?
