[gradsusr] Using scorr function

[Dr. Suman Maity]

Hi Suneela
Your question is somehow very fishy. The "scorr" function in grads produces
spatial correlation which provides single numeric value. Perhaps, you mixed
spatial correlation with temporal correlation (where we are getting a
spatial map).Therefore "no result is displayed" is not clear to me.
However, for only the spatial correlation,
'reinit'
'sdfopen E:/lh.nc'
'sdfopen E:/sh.nc'
'd scorr(lhtfl, shum.2, lon=30, lon=90, lat=0, lat=30)'
This is sufficient and provides the correlation vlue 0.8 which the spatial
correlation for t=1 (1st time step).
I hope it helps.
Cheers!!!!!

Best
Suman
