[gradsusr] How to set time attribute in sdfwrite

[Charles Seman]

Zablone,

I'll forward a couple of emails from Jennifer Adams who helped me put a 
time axis on a GrADS sdfwrite netCDF output file (the input netCDF file 
had no Z or T dimension...).  In essence, the solution involved defining 
a data descriptor file to open the input netCDF file to define the time 
axis... I'm not sure what your input dataset attributes look like, so 
I'm guessing here...  If you have questions or want sample code from a 
script, feel free to email me.

Hope this helps,
Chuck
