The Regridder algorithm requires:
- Center coordinate names as lon and lat
- Corner coordiante names as lon_b and lat_b
The gridtools library will standardize on these to common variable names.
It was determined that the lon grid points need to run from -180.0 to +180.0 instead from 0.0 to 360.0.
Regridding for grids that require periodic=True has a problem over the dateline. A fix is in the work for this in a future xesmf version. The gridtools installation points to a fixed version temporarily.
