John-The problem is not being able to read the raw WRF output, but the fact that to really be useful, you need to do some post processing to get standard meteorological variables like sea level pressure and remove the staggering.
Post processing to GEMPAK or GRIB would be the best way to accomplish this. Don On 3/6/15 9:12 AM, John Caron wrote:
Hi Brian: IDV should be able to read WRF output without conversion to CF. If not, send me the problem file and ill see why.

What you need to do depends on where these auxiliary files were installed. Normally the are installed in a subdirectory of the 'lib' directory. Based on the path to your NCL executable, /usr/local/bin/NCL/bin/ncl, look in /usr/local/bin/NCL/. If you find a 'lib' directory there, it should have a subdirectory called 'ncarg'. Set the environment variable NCARG_ROOT to /usr/local/bin/NCL/ and you should be good to go. If instead you find the 'ncarg' directory somewhere else, say /usr/local/lib/ncarg or /usr/local/lib/NCL/ncarg, try setting NCARG_NCARG to that path. If that doesn't work, let us know, and we can definitely help you figure it out. -Dave Brown NCL Development team On Thu, Mar 5, 2015 at 4:33 PM, Tyle, Kevin R <ktyle@xxxxxxxxxx> wrote:Hi Brian, Have you tried using GEMPAK as an interim format? I've had good results using the venerable wrf2gem postprocessor thatSteve Decker developed several years ago. The netcdf-java library handles the GEMPAK to NetCDF conversion fine and I have a couple bundles that display fields from our regional runs.I believe that if you build NCEP's WRF post processor and choose GEMPAKoutput, that will work too.--Kevin _____________________________________________ Kevin Tyle, Systems Administrator Dept. of Atmospheric & Environmental Sciences University at Albany Earth Science 235, 1400 Washington Avenue Albany, NY 12222 Email: ktyle@xxxxxxxxxx Phone: 518-442-4578 _____________________________________________ ________________________________________ From: idvusers-bounces@xxxxxxxxxxxxxxxx <idvusers-bounces@xxxxxxxxxxxxxxxx> on behalf of Brian Mapes < bmapes@xxxxxxxxxxxxxxx>Sent: Thursday, March 5, 2015 6:04 PM To: idvusers Subject: [idvusers] making WRF output CF compliant Does anyone have some one-line templates for converting wrf output toIDV-friendly netCDF files?Preferably with a set of basic weather variables but not a zillioninternal model fields.Such an old question, so much on the Web, yet every solution seems torequire a bunch of time and effort.This looked promising http://foehn.colorado.edu/wrfout_to_cf But for me it creates the inscrutable errors below and no results.
