You can use the sum function in GrADS to calculate x-hr accumulated rain from n-hr accumulated rain, where x>n. If x<n, you can use subtraction, as in ACPCsfc(t-4)-ACPCsfc.

Hi, my WRF plots 17 files, from 00h to 48h, with 3h steps; so rain is accumulated each 3 hours.
BUT how could I have 12h and 24h accumulated rain with grads? So that I have respectively 4 and 2 images :)
Thanks,Giacomo
