 and used in several published hybrid machine learning projects.  Much of the
 code is identical or nearly identical to this original wrapper; the main
 difference is that the wrapper in this repository wraps the latest public
-version of GFDL's SHiELD model instead of an old fork of FV3GFS.  At this

-changes are made to SHiELD.
