- ESMF = ESMF Regridder, supports aave, bilinear and patchmap options.
- Tempest = TempestRemap
TempestRemap has several new algorithms with native support for spectral element meshes. These algorithms may eventually be implemented in ESMF, so below when we mention TempestRemap, we are referring to the algorithm, not the tool used to compute the maps. For spectral element source meshes, Tempest conserve (non-monotone) is the most accurate map available and is suitable for upscaling and downscaling. It is a good replacement for ESMF bilinear and patchmap options. Tempest conserve+monotone is a potential replacement for ESMF aave maps, but it has two issues that must be resolved before it should be used in an ACME compset: (1) consistent reference element map between HOMME and TempestRemap, and (2) element-scale artifacts that show up in the land mask defined on the atmosphere grid. These issues are being worked on under the SciDAC Multiscale project.
