[gradsusr] Spatial Correlation

[Muhammad Latif]

Yes Kishore, the spatial resolution is same for both the datasets. But the
function (scorr) you have mentioned is valid only for one box (I have four
lat. and four lon. values, which are required to draw two boxes). Please
share, If you have any idea.

Thanks

Regards
