[IDV #YQP-594813]: Wrfout_d01

Hi Brian-

The raw netCDF files are staggered and on non-pressure coordinates.  This
creates a huge overhead for the IDV to do the conversion on the fly.

We suggest using the WRFPost code to do the conversion to pressure or
height coordinates instead of using the raw netCDF files.  That code
has been well tested and verified.

I know Gary Lackmann converts his WRF output to GEMPAK and reads that
into the IDV.  That is another option if you want to use the grids in
IDV and GEMPAK.
