GrADS help

[Fredrick Mashingia]

Hi everybody,
 
I am trying to appy the GSMaP-TMI hourly precipitatition data(in grads format) over Africa and I can display the data( for the events of 19th to 22nd April 1999,28th to 30th April 1999 and 14th to 18th May 1999) using GrADS 1.9b4 in FC5 OS machine. I would like to ask if it is possible to extract time series data (in text format) from each GrADS lat/lon grids in my 52 sq.km catchment located between lon 37019’08’’E and 37024’15’’E, and lat 3004’33’’S to 3017’14’’S at an elevation between 1000masl and 5895masl (the summit of Mt.Kilimanjaro). And also if it is possible to change the GrADS lat/lon grids into match with my model grid resolution. I understand the two operations can be done under ArcView environment easly but then I dont know how one can convert grads data into arcview shapefiles. Please if you can help I should be very grateful.
 
Kind regards,
 
Fredrick
