<DIV>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</DIV>
<DIV> </DIV>
<DIV>I am sure that there is a better or more streamlined approach, but this cavalier method should work.<BR> </DIV>
