[gradsusr] Sub regions

[Lee Byerle]

Steven,

If you have wgrib2 and g2grb.gs, you can create a grib2 file for your  
subregion using grads.

See:

http://www.cpc.ncep.noaa.gov/products/wesley/g2grb.html

Here is an example that would put 6 records in a single grib2 file:
'open your_file.ctl'
'set x  __ __'
'set y __ __ '
'g2grb h(lev=1000) extrap.grb HGT:1000 mb:anl:packing=j:center=7'
'g2grb h(lev=925) +extrap.grb HGT:925 mb:anl:packing=j:center=7'
'g2grb h(lev=850) +extrap.grb HGT:850 mb:anl:packing=j:center=7'
'g2grb h(lev=700) +extrap.grb HGT:700 mb:anl:packing=j:center=7'
'g2grb h(lev=600) +extrap.grb HGT:600 mb:anl:packing=j:center=7'
'g2grb h(lev=500) +extrap.grb HGT:500 mb:anl:packing=j:center=7'
