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

[Teddy Allen]

You can easily retrieve TRMM data in a netcdf format from the IRI data library 
so that it is easily read into grads. 

Go to: 
http://iridl.ldeo.columbia.edu/SOURCES/.NASA/.GES-DAAC/.TRMM_L3/.TRMM_3B42/.v6/.daily/.precipitation/

From there you can subset your data (click on data selection link) then download 
into NetCDF (data files selection link). Or you can even access the OpenDAP link 
as well.

Once you have this TRMM NetCDF file you can then easily ingest into GrADS 
through:
'sdfopen filepath/filename.nc'
'd precip'

hope this helps,
teddy

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

Hi! All, 

I am a beginner in using GrADS to process TRMM data. The question I have are:

(1) To process TRMM (3B42 daily and 3hr) data for a period of 5 years. Do I need 
to write a script or a template control file(.ctl) is to be created?
(2) Are there any tutorials available in using GrADS for TRMM data?


Thanks and Regards,
