List of resolution combinations that

, how made.

Preferred Tool = tool ACME wants to use uses to make mapping files.

  • 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.  

...

As a caveat - CICE in prescribed mode (as is the case for F compsets) also uses the domain file to determine its grid and mask."

High Res Transition Grid (Proposed)

For use as a high-throughput testing case for tuning v1 low-res atmosphere coupled to eddy permitting ocean (avoids biases from ocean eddy parameterization that will be in the medium res grid but not in the high res grid).  
Per coupled model group:  Decision on if this grid will be used to be based on cost vs the medium resolution (BGC) grid.  It is possible that this configuration will only be slightly more expensive than the medium resolution BGC grid, while having biases similar to the high-res grid.  Hence this configuration might be a better warmup problem for high-res then using the BGC grid.
