Up until the last IDV release, there were some issues with this. Please be sure you're running IDV 1.2b2. In addition, if your file is not too big, would you please post it to an ftp server so we can see what the issues are?

I have a netcdf file that the CF convention checker (http://titania.badc.rl.ac.uk/cgi-bin/cf-checker.pl) likes. IDV is supposed to like CF data, even the 2 D grid data like my file. I have included the first few lines of my cdl file from ncdump and am wondering if anyone could give me a few pointers on how to correct the file for IDV compatibility.
Thanks in advance.
