<td valign="top">Hi,
<div>I'm new to the CDO program and GRaDs,my GRaDs version is 2.0.a8.I have some forecast outputs that i have been trying to view with GRaDs, i tried to make a descriptor file in order to use the GRaDs software, i used the "gradsdes1" command but it only makes a descriptor file with 2 variables out of the 49 that each forecast contains, also it states that "lonlat grid unsupported, skipped variable var49 " and so on for the other 47 variables.</div>
<div>The forecast output is for a rotated grid which i know can lead to difficulties, When i check the discriptor file only 2 variables are available, also when i try to display it in GRaDs it states "entire grid undefined" set to missing data</div>
<div>Just looking for help as to what i need to do to rectify the problem, or any advice would be much appreciated, </div><div>thanks in advance,</div>
<div>regards</div>
