[gradsusr] sdfopen and open

[Jennifer Adams]

The syntax of your descriptor file TES_data.ctl is incorrect. Please read http://iges.org/grads/gadoc/SDFdescriptorfile.html carefully. 

dset ^TES-Aura_L2-CO-Nadir_2006-06_L2v005_Litev003.nc
title TES
undef -999.f
dtype netcdf
xdef 360
ydef 180
zdef 14
TDEF 00:00Z01Jun2006
VARS

Also, I'm not sure whether Aura L2 data is gridded or swath data. If it is swath data, then GrADS is not the right tool.
