SCM with Ocean Model

[dustinswales]

Recently there has been some interest in adding the ability to couple the SCM with a simplified(?) ocean model.
From a technical perspective the pathway to implementation is ~straightforward, and could be accomplished by providing the state to the ocean model somewhere in scm_time_integration.F90.

@grantfirl You have more experience with the SCM, but "I think" if we build a component ocean model as part of the SCM build, then can we call it in scm_time_integration.F90?
@yangfanglin I'm out of my lane when it comes to ocean models, so I can't speak to what the interface would look like, but conceptually this appears to be feasible.

@dustinswales Thanks for picking up the conversation we had at the UIFCW meeting last week. The coupling can be made to a simple 1-D mixed layer ocean model or a more complete ocean model like MOM6 if a 1-D version exists. I have a 1-D mixed-layer ocean model of intermediate complexity https://www.emc.ncep.noaa.gov/gmb/wx24fy/fyang/www/modexp/mlo.html. For forecasts at MRW/S2S time scale, the relaxation of (T,S) to climatology and horizontal advection terms can even be turned off /ignored. This is one option and it is fine to use any other mixed layer ocean model.
