Reading NCEP-DOE AMIP-II Reanalysis (AKA Reanalysis-2) file w/GrADS

[Don Hooper]

Chenghai Wang,

Why are you writing a Data Descriptor File (DDF, what you call a "ctl"
file) for this NetCDF file?  It works fine directly with the sdfopen
command.  I should know; I wrote both the file and the sdfopen code.
