[gradsusr] Error in Temporal Correlation

[Jayakrishnan P.R]

Dear Sourabh,
       I am afraid your SST is 1 degree resolution and the rainfall is 0.25
degree. Just check this. To perform any correlation we need to have both
the input files as same dimension. If not you will have to regrid the other
to 0.25 or vice versa. Just a thought. Best Wishes.
