Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

Re: File Formats

Hi Ken:
You probably need to add the attribute 
 :positive = "up";

to your altitude variable, see CF-1.0 section 4.3

Perhaps this belongs on the netcdf mailing list, but I thought I'd post here first.
I've created a netcdf file, and IDV says "No gridded data found for /path/to/file, would you like to try another source". This is if I have one of my axes as "altitude" with units "meters", which is a CF standard I think. If I change "altitude" to "pressure" and "meters" to "hPa", then the data loads in IDV. 

What am I doing wrong when creating this file?

Thanks,
