[gradsusr] WAFS GRIB2: Cannot contour grid - all undefined values

[Matthew Grzych]

I am having no luck getting WAFS GRIB2 files to plot in GrADS and get the "Cannot contour grid - all undefined values" error after many hours of trying seemingly everything. I am downloading the files from:


http://www.ftp.ncep.noaa.gov/data/nccf/com/gfs/prod/gfs.2013121212/WAFS_blended_2013121212f06.grib2

Then I generate the control files using g2ctl.pl and index files using gribmap. Here's an example ctl file:
