Hi! Sravan

Another way would be to create a ".ctl" file using template.  The contents of 
.ctl file is shown below..

dset ^3B42.%y2%m2%d2.%h2z.bin             
title TRMM Global daily total rainfall
undef    -9999.0
options big_endian template
xdef 1440 linear  0.125   0.250
ydef  400 linear   -49.875   0.250
zdef 1 linear 1 1
tdef   9  linear 00z04Jan2011 3hr
vars  1
r 0 99 3 hourly rain rate (mm)
endvars


Regards,
Subash

I suppose the long method would involve opening them all up through unique ctl 
files (different variable name for each file, ex: r1,r2,r3,etc...). Then in 
GrADS simply define a new variable , rTOT = r1 + r2.2 + r3.3.....   , then d 
rTOT
