[gradsusr] Filtered rainfall series

[Satyaban BishoyiRatna]

Dear all,
I have spatially distributed daily rainfall data series.
I would like to prepare area averaged filtered rainfall series which retains information on 10-60 day mode.

Can you please suggest me how can I prepare filtered rainfall series using GrADS script.

Thanks.
Regards
Satyaban
