<div dir="ltr">Your control files appear to contain data valid at different times. You need to adjust the time dimension. Since you appear to want to display a rain sum between two files valid at different times, you must use a time string to change the valid time of one of the files. In other words, you will need to do something like<br>
<br>d rainnc.1+rainnc.2(time=03Z06JUN2011)<br><br>if you opened the files you listed above in chronological order. The time dimension in Grads is set by default to whatever the first time step in control file #1 (the first control file you opened) is. You can use 'set dfile N', where N is the file number, to change this default behavior, but you will still have to input a time string on all but one of the rainncs to do a sum from files valid at different times.<br>
