Dear Spandana,<div><br></div><div>I suppose you are using GrADS 2.0+. In that case I suggest that you can use CDO (<a href="https://code.zmaw.de/projects/cdo" target="_blank">https://code.zmaw.de/projects/cdo</a>) to make your data readable in GrADS. </div><div><br></div><div>The CDO command is: "setcalendar,<b> option</b> inputfile.nc outputfile.nc'' . U will see the calendar <b>options</b> in the user manual. Your data appears to be CMIP output, if so "setcalendar, <b style="text-indent:0px !important">standard</b> inputfile.nc outputfile.nc'' should produce an output of the same data readable by GrADS 2.0+.</div><div><br></div><div><br></div><div>2. Alternatively, the older version of GrADS, say 1.9 should read ur data as it is. You may wish to instal and use it.</div><div><br></div><div>Best,</div><div><br></div><div>Hyacinth</div><div><br></div><div><br></div><div><br></div><div>> <br>> Message: 5<br>> Date: Mon, 13 Jun 2011 12:53:37 -0400<br>> From: "Tummuri, Spandana" <tummuris@cdm.com><br>> Subject: [gradsusr] SDF Error: 365 day calendars are no longer<br>> supported by sdfopen.<br>> To: "gradsusr@gradsusr.org" <gradsusr@gradsusr.org><br>> Message-ID:<br>> <6906BEEB113AEB48B9910246026EA9BED1750F2785@CAMEXCMS3.cdminc.internal.cdm.com><br>> <br>> Content-Type: text/plain; charset="us-ascii"<br>> <br>> Hello Everyone,<br>> <br>> I was wondering if one of you would be able to tell me how you addressed this issue.<br>> <br>> I am not very good at GRADS programming. I only needed to use it to open a ".nc" file and get some values averaged over a period of time. So I typically use the following three commands in grads.<br>> <br>> Sdfopen "filename.nc"<br>> Run monmask.gs N ...................(N = month)<br>> d ave(aave(pr*mmask, lon=lon1, lon = lon2, lat = lat1, lat = lat2),t=time1,t=time2)<br>> <br>> This worked for a few files but when I tried to use it on some others, I get the follo
