What in CF will not work for your data?  Are you using staggered grids?  If
you are not using staggering, then I think the CF could be used.  Could
you please elaborate on your data?

We are working to add support for WRF version 2.0 netCDF output to the
IDV.  At this point, the IDV 1.1 version has minimal support and we are 
debugging the problems we've seen.  Most of the problems with the WRF netCDF 
output is the use of non-standard unit specifications and inadequate projection
information.  

You can find a sample file at:
