ESMF seems to do a 3D interpolation in order to "regrid" pixels, which it defines (rather well) as http://www.earthsystemmodeling.org/esmf_releases/public/ESMF_5_2_0rp1/ESMF_refdoc/node3.html#SECTION03020000000000000000 > Regridding, also called remapping or interpolation, is the process of > changing the grid that underlies data values while preserving > qualities of the original data. ... > The regridding occurs in 3D to avoid problems with periodicity and > with the pole singularity. But ESMF only seems to work with data that's attributed to a 2D grid, rather than data attributed to a 3D grid ... unless I'm missing something. your assistance is appreciated, Tom Roche <Tom_Roche@xxxxxxxxx>
