<P></P><B>Subject</B>: reading in a netCDF file from NARR
<P></P>
<P></P>> I have been trying to read in a netCDF file that was creasted <BR>> using the NARR monthly composite site. I've tried sdfopen and I <BR>> tried using xdfopen with a descriptor file, however, I'm not sure <BR>> if I configured the descriptor file correctly. I've even tried <BR>> the narropen.gs script on the script library page, but again, not <BR>> sure if I am inputting the correct variables. I was wondering if <BR>> anyone has any clue as to how to get this file open. <BR>> Also, for some reason, sdfopen and xdfopen is not recognized as a <BR>> command in grads.2.0.a7.1...at least at school, but xdfopen seems <BR>> to work ok at my office at work, not sure why that would be as <BR>> well (they are both the same versions). <BR>> Any help would be GREATLY appreciated. <BR>> Joe <BR>> </BODY>
