grib2ctl

You might want to install and try
Climate Data Operators (cdo) found at
http://www.mpimet.mpg.de/fileadmin/software/cdo/

To create a GrADS data descriptor file from a GRIB dataset use:

> cdo gradsdes2 infile.grb

This will create a descriptor file with the name ifile.ctl and the map file
ifile.gmp.
I hope this helps.
