Jason,

Just because the cdl is used with AWIPS doesn't mean it will work/follow
conventions with gribtonc. A simple test would be to test the cdl on the
command line. 

% ncgen -o output.nc  awips.cdl

This will create an empty output.nc file with all the define variables or 
complain about problems. You will probably have to modify the the
awips.cdl file with the assistance of gribdump utility on the grib file.
gribdump is built along with gribtonc.
