1. fluxes:  FV→FV mono
2. state variables:
   1. ocn→atm: currently this map must be the same as used for fluxes (FV→FV mono)
   2. lnd↔atm and atm→ocn
      1. if source grid resolution >> target grid resolution:  "FV→FV mono"  
      2. source grid resolution <= target grid resoluiton:  ESMF's bilin
      DESIRED:  a version of intbilin for FV source grids.
      1. . (replace by FV→FV intbilin when it becomes available) 

Recommended Settings:   For E3SM v1 type configurations
ATM SE grids with physics on the "np4" grid (used in V1), coupled to FV ocean and FV land

1. SE → FV  for fluxes:  use "SE→FV mono" 
2. SE → FV for state variables: SE->FV intbilin
3. FV → SE for fluxes:  FV→SE monotr
   1. The best map is the transpose of the SE->FV map computed above:
   2. This is the most important map, as it is used to compute the domain files and defines the ocean/land mask on the atm/land grid.  
4. FV → SE for state variables
   1. ocn→atm: currently this map must be the same as used for fluxes (FV→SE monotr) 
   2. lnd→atm:   if land grid resolution >> atmosphere resolution:  "FV→SE mono". 
   3. lnd→atm:   if land grid resolution <= atmosphere resolution:   ESMF's bilin.  DESIRED:  a version of intbilin for FV source grids.  It's tempting to consider  "intbilintr", but the transpose of a nonconservative monotone map is not monotone.    (replace by FV→SE intbilin if it becomes available)

Recommended Settings:   Atm to/from Lat/Lon maps for analysis and interpolating input data:
