@SamuelTrahanNOAA Thanks for getting this ready for retro testing.
I understand that this is still a draft PR. But a heads up that the polygon generation will only need to run once for each domain in its lifetime. So we will NOT include lines 139-143 in exrrfs_jedivar.sh, but instead run it manually once and then put the results somewhere (either as a fix file or as a exp setting option).

Perhaps we can do this?

  1. Add a variable $BOUNDARY_POLYGON_YAML
  2. If that variable is set to a valid path, use that file,
  3. Otherwise, automatically generate it.

A side-effect of the automatic generation fallback is to give you the polygon boundary file you need to put in parm/
