Hello,
 
I had run RegCM3 with 2007 datasets. Now I am trying to plot its rainfall variable that is available as 'tpr' (total precipitation)
in SRF.yyyymmddhh.ctl. but
as i want its rainfall values only for Indian land region so I don't know which program or file of Regcm model I should use.
I have already got the plot with rainfall values but it includes sea also. 
 
May anybody tell me how to plot rainfall only on land using grads in RegCM.
 
waiting for reply.
 
Thanks
 
 
 
Regards,
