[IDV #EUJ-470419]: Error loading WRF NetCDF files: "Dimension time does not exist"

Hi Jim,

The definition of the Times variable is only valid for the WRF dataset, so you 
need to add one global attribute:

_CoordSysBuilder = "ucar.nc2.dataset.conv.WRFConvention";

And the Data Source Type need to be "Aggregate WRF netCDF grids by Time".

Give it a try.
