Does the currently-available NCL API for ESMF_regrid only support lon-lat? My impression was
http://www.earthsystemmodeling.org/esmf_releases/non_public/last/regridding_status.html
> Options for coordinate systems
> * Cartesian: Sometimes used for small regional grids. Coordinates
> expressed in terms of distance (e.g. x,y)
> * Spherical: The standard spherical Earth representation. Coordinates
> expressed in angles. (e.g. longitude, latitude)
so I've been working for awhile toward 3D-regridding (with InterpMethod=
"conserve") source data that is horizontally global/lon-lat/spherical
into a target format that must be regional (CONUS) and Cartesian (LCC),
which I have discussed on this list. But I notice
http://www.ncl.ucar.edu/Document/Functions/ESMF.shtml
> ESMF_regrid
> Regrids data from one lat/lon grid to another, using ESMF software.
> ESMF_regrid_gen_weights
> Writes a weight file using the offline ESMF weight generator.
> ESMF_regrid_with_weights
> Using the provided weight file, regrids data from one lat/lon grid
> to another.
http://www.ncl.ucar.edu/Document/Functions/ESMF/ESMF_regrid.shtml
> Regrids data from one lat/lon grid to another,
and further text on that page seems to imply (please correct me if
wrong!) that the NCL implementation does *not* support ESMF_regrid
from a source Cartesian grid to a target/destination Cartesian grid.
Am I missing something?
