Re: Plot a regridded file and incorrect map

  Hi Adam,

You are completely right when you point at the regridding coding, because I
noticed an inconsistency between the raw netcdf file grid and grid
descriptor file, which resulted in shift. The things are correct now when
using the updated file.

Thanks,

Deniz
