Re: loacation deviation after interpolation_wrf data

Hi Xiaoman,

If the regridded precipitation values are not showing up in the correct location, it could be because gsn_csm_contour_map doesn't have any lat/lon information.

It would help if we could see your full script (or at least the part where you are plotting pgrd: I need to see *all* of your "res" settings) and the output from:

printVarSummary(pgrd)

It would also help if we could see an image.
