[gradsusr] Spatial Correlation

[Kishore Ragi]

you need to have same resolution for both the datasets so that you can
calculate the spatial correlation as below

open two datasets as 1 and two and invoke the following command

scorr(*var.1, var.2*, lon=x1, lon=x2, lat=y1, lat=y2)

hope this helps!

Regards,
Kishore
