Just open each file (or appropriate control file) in grads then plot tm2.1 then plot tm2.2 (tm2 being whatever your temperature variable is called). If you actually want to plot the difference, you have to interpolate. I believe there is a built in re2 function in grads 2.0, in older versions you have to use the
regrid2 udf. There are lots of messages about these routines in the grads user list archive (which should be moved to the new location by now?).<br><br>Michael Sestak<br>Fleet Numerical Meteorology and Oceanography Center<br>Monterey, CA <br><br>-----Original Message-----<br>From: <a ymailto="mailto:GRADSUSR@LIST.CINECA.IT" href="/mc/compose?to=GRADSUSR@LIST.CINECA.IT">GRADSUSR@LIST.CINECA.IT</a> [mailto:<a ymailto="mailto:GRADSUSR@LIST.CINECA.IT" href="/mc/compose?to=GRADSUSR@LIST.CINECA.IT">GRADSUSR@LIST.CINECA.IT</a>] On Behalf Of Rupesh Patil<br>Sent: Saturday, March 20, 2010 5:48<br>To: <a ymailto="mailto:GRADSUSR@LIST.CINECA.IT" href="/mc/compose?to=GRADSUSR@LIST.CINECA.IT">GRADSUSR@LIST.CINECA.IT</a><br>Subject: (NCEP 1degree x 1 degree - model output 0.7x 0.7degree ) temperature pattern in GrADS<br><br><br><br><br><br>Dear Grads users,<br> <br> I have to compare model output of temperature with NCEP 1degree x 1 degree data .
