[gradsusr] netcdf - descriptor file ctl

[Jennifer Adams]

The units field of your variable declaration is incorrect -- it needs to have a comma-delimited list of the varying dimensions of the variable, something like t,y,x or t,z,y,x. Also, you are aliasing ET to ET -- change that to ET=>et (GrADS wants lower case alphanumeric characters). If you are still having problems, please send the output from ncdump.h as well as your descriptor. GrADS version would also be useful.

p.s. Please read the documentation at http://iges.org/grads/gadoc/SDFdescriptorfile.html
