<div><font color="#17365D">Hello Everyone,</font></div>
<div><font color="#17365D"> </font></div>
<div><font color="#17365D">I was wondering if one of you would be able to tell me how you addressed this issue.</font></div>
<div><font color="#17365D"> </font></div>
<div><font color="#17365D">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.</font></div>
<div><font color="#17365D"> </font></div>
<div><font color="#17365D">Sdfopen “filename.nc”</font></div>
<div><font color="#17365D">Run monmask.gs N ……………….(N = month)</font></div>
<div><font color="#17365D">d ave(aave(pr*mmask, lon=lon1, lon = lon2, lat = lat1, lat = lat2),t=time1,t=time2)</font></div>
<div><font color="#17365D"> </font></div>
<div><font color="#17365D">This worked for a few files but when I tried to use it on some others, I get the following error</font></div>
<div><font color="#17365D"> </font></div>
<div><font color="#17365D"> </font></div>
<div><font color="#17365D">ga-> sdfopen pr_A1.nc</font></div>
<div><font color="#17365D">Scanning self-describing file: pr_A1.nc</font></div>
<div><font color="#17365D">SDF Error: 365 day calendars are no longer supported by sdfopen.</font></div>
<div><font color="#17365D"> To open this file with GrADS, use a descriptor file with </font></div>
<div><font color="#17365D"> a complete TDEF entry and OPTIONS 365_day_calendar. </font></div>
<div><font color="#17365D"> Documentation is at <a href="http://iges.org/grads/gadoc/SDFdescriptorfile.html"><font color="#0000FF"><u>http://iges.org/grads/gadoc/SDFdescriptorfile.html</u></font></a></font></div>
<div><font face="Calibri, sans-serif" size="2" color="#17365D"> </font></div>
<div><font color="#17365D">When I compared NCDUMP for the files for which “sdfopen” worked with the those for which “sdfopen” did not work, I noticed that the calendar has to be gregarian for sdfopen to work.</font></div>
<div><font color="#17365D"> </font></div>
<div><font color="#17365D">Can you tell me how I can open files that have “noleap” calendars and work around the 365_day_calendar issue?</font></div>
<div><font color="#17365D"> </font></div>
<div><font color="#17365D">I greatly appreciated your help in this matter.</font></div>
<div><font color="#17365D"> </font></div>
<div><font color="#17365D">Thank you.</font></div>
