For PG2 grids, we currently do not have an acceptable solution that would allow us to run at 3km (ne1024).
TempestRemap: Highres maps have poor conservation and consistency (1e-6).
MBTempestRemap: NaN’s or too large weights. conservation/consistency errors similar to TR.
ESMF: For PG2 grids, we can rely on ESMF ‘aave’ maps, which are good up to ne512pg2. Unacceptable at ne1024pg2
For NP4 grids, Ben Hillman has been using TR mapping files with similar conservation/consistency errors. These are acceptable for development/testing, but not appropriate for coupled simulations.
