It sets the dimension environment to vary in time (monthly in this case) over one year (1979) from January to December, which is what you need to do before calculating a monthly climatology. If the monthly dataset began in December rather than January, use 'set t 2 13' instead.</div><div><br></div><div>Eric<br><br><hr id="yiv1874406172zwchr"><b>From: </b>"Luis Blacutt" <luis.blacutt@gmail.com><br><b>To: </b>"GrADS Users Forum" <gradsusr@gradsusr.org><br><b>Sent: </b>Wednesday, April 3, 2013 2:02:18 PM<br><b>Subject: </b>Re: [gradsusr] Creating Climatology<br><br><div dir="ltr">Also, you don't need the<div>'set t 1 12' <br></div><div style="">command line, and I agree with Eric, that only line is
