Merge from AM3 - overarching series of merges across directories

[JhanSrbinovsky]

In order to preserve links therein:

Double-handling of work that was previously done via creation of a quasi trunk, consecutively branching of this quasi-trunk to implement (in order of development built on top of preceding branch):

363_coupled
363_params
363_science
363_canopy

Note: This is AM3 development PRIOR to several modifications resulting from Surface water/energy balance work.

363_coupled merged into main AT 0448257

363_params development branched from 0448257. PR AT #404

363_science begin merge AT issue #414 - this WILL be resubmitted (as $439) after #404 is pushed to main and we can rebase

[JhanSrbinovsky]

AM3 modified params pushed to main in #404

[JhanSrbinovsky]
