Up until the last IDV release, there were some issues with this. Please besure 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 issupposed to like CF data, even the 2 D grid data like my file. I haveincluded the first few lines of my cdl file from ncdump and am wonderingif anyone could give me a few pointers on how to correct the file forIDV compatibility.

Thanks in advance.
