  1. fluxes:  FV→FV mono
  2. state and vector maps:  
    1. ocn→atm: currently this map must be the same as used for fluxes (FV→FV mono)
      1. This restriction is because the range of the state and vector maps must match the range of the flux map.  
    2. lnd↔atm and atm→ocn
      1. if source grid resolution >> target grid resolution (fine-to-coarse):  "FV→FV mono"  
      2. if source grid resolution <= target grid resolution (coarse-to-fine):  use ESMF's bilin.(will be replaced by
      3. New as of 2022/10:  TR's FV→FV intbilin when it becomes available) should work well for all resolution combinations, replacing both maps above.  Not yet tested in E3SM.  

E3SMv1

ATM SE grids with physics on the "np4" grid (used in V1), coupled to FV ocean and FV land. E3SMv1 uses the same spectral element GLL grid for both dynamics and physics in the atmosphere, so coupling between components happens on this grid.
