The purpose of this page is to document the procedure for adding support for new atmosphere grids. The process should be the same for new uniform resolutions as well as for new regionally-refined meshes, although some settings will need to be changed for new regionally-refined mesh configurations. This page is a work in progress, and will be updated as this process is refined and (eventually) made more automated. This documentation is an update of a document written by Mark Taylor and Colin Zarzycki, available as a Google Doc here.

Requirements:
exodus mesh file
Matlab or Fortran utility.homme_tool
Note: in E3SM v2, we switched to running physics on a FV pg2 grid and mapping files between the atmosphere and other components will be FV to FV type maps using the pg2 grids. The spectral element "np4" grid is still used internally by the dynamics and for initial conditions, so the metadata described in this section is still needed for some analysis and preparation of initial conditions.
