[gradsusr] Few basic questions on processing of TRMM data in GrADS

[luis blacutt]

Dear Subash,

I work with TRMM data, I preferred to work with xconv, I convert every
single file to a grib file, then you can merge them as a single file and
calculate averages and so on  (it is also possible to reconvert them to
netcdf format).

Regards
Luis
