[gradsusr] template for multiple netcdf files

Fri Mar 11 00:04:07 EST 2011

Thanks Jennifer. Looks like I'm getting close.
After I removed "time" in TDEF it complained and wanted xdef, ydef,  
etc. I input that info and  can now "open" the file with no errors but  
cannot display anything. "Entire Grid Undefined".

Control file now looks like

DSET ^ta_6hrLev_HadGEM2-ES_rcp45_r1i1p1_%y4%m2%d2%h200-%y4%m2%d2%h200.nc
