[gradsusr] Using g2ctl.pl/gribmap with Monthly CFSR Data

Tue Nov 2 19:31:30 EDT 2010

It looks like gribmap is not matching any records. My descriptor for  
this cfsr data is attached:

And my gribmap -v -b output looks like this:

grib2map: scanning GRIB2 file: pgbhnl.gdas.197901.grb2
1.1: lev1=101,0 var=0,3,0,194 pdt=8   MATCH
2.1: lev1=100,100 var=0,3,5,194 pdt=8   MATCH
3.1: lev1=100,100 var=0,0,0,194 pdt=8   MATCH
4.1: lev1=100,100 var=0,1,1,194 pdt=8   MATCH
5.1: lev1=100,100 var=0,1,0,194 pdt=8   MATCH
6.1: lev1=100,100 var=0,2,8,194 pdt=8   MATCH
7.1: lev1=100,100 var=0,2,2,194 pdt=8   MATCH
7.2: lev1=100,100 var=0,2,3,194 pdt=8   MATCH
8.1: lev1=100,100 var=0,2,10,194 pdt=8   MATCH

So, I'm puzzled. Are you sure you're really using gribmap from version  
2.0.a9 ??
