NEW WAVE MOMENTUM COUPLING FEATURE
Full momentum coupling between WW3, MPAS-Ocean, and EAM is being implemented.
This discussion is for the purpose of getting a preliminary code review and feedback before an official PR is opened into E3SM.
This PR uses COARE3.0 flux calculation which is needed for wave coupling to atmosphere via charnock parameter.
The use of WW3 is 'stealth' in that WW3 is NOT a standard component of E3SM for production runs. However, the implementation of wave-ocean-atm coupling in this PR defines the default coupling based upon the COMPSET used.
For example, a fully coupled base with active waves (B compset + WW3) will assume full, two-way coupling between WW3-EAM-MPASO and MPAS-SI. (note: limited wave-ice coupling for now, full wave-ice coupling coming in near future). On the other hand, if a data atmosphere used, like in a G Case+WW3, EAM-WW3 coupling will default to "one-way" (data winds passed to WW3) while full two way coupling is used between the active components of WW3 and MPAS-O/MPAS-SI.

A table summarizing all testing being performed is at the bottom of the page here: https://acme-climate.atlassian.net/wiki/spaces/OO/pages/4271702034/2024.Q2+WAVEWATCH+III+maintenance+developments Suggestions welcome for additional testing that is needed to open a PR into E3SM. a 100 year Fully coupled Simulation is currently being done.
