[IDV #DJW-860349]: IPV calculations

Hi Ronnie-

The IDV needs to have grids with a pressure or height domain to do the 
calculation of IPV, but you are reading in raw WRF grids which have the WRF Eta 
coordinate.

We strongly suggest that you use a post-processing program on the raw WRF 
output before loading it into the IDV.  Set the FAQ at:
