Description

This PR aims to enable receiving atmosphere-ocean fluxes from external component such as CMEPS mediator. This is required to enable usage of exchange grid capability provided by CMEPS mediator to calculate atmosphere-ocean fluxes. It defines required data structures to send flux components to CCPP/physics and also introduces new input.nml option called as use_med_flux to the gfs_physics_nml group. The default value of the new option is .false. and the FV3/CCPP Physics will not accept any flux from external sources. This allows to preserve the existing functionality in the FV3 side. With this change there is no any expected answer changes.

Testing

How were these changes tested?
The modifications are tested under UFS weather model by running full RT suite

What compilers / HPCs was it tested with?
NCAR's Cheyenne with Intel+MPT combination

Are the changes covered by regression tests? (If not, why? Do new tests need to be added?)
Yes. New RT (cpld_control_c96_p8_xgrid) is added in UFS level.

Have the ufs-weather-model regression test been run? On what platform?
NCAR's Cheyenne with Intel+MPT combination

  • Will the code updates change regression test baseline? If yes, why? Please show the baseline directory below.
    No

  • Please commit the regression test log files in your ufs-weather-model branch

Dependencies

If testing this branch requires non-default branches in other repositories, list them.
Those branches should have matching names (ideally)

Do PRs in upstream repositories need to be merged first?
If so add the "waiting for other repos" label and list the upstream PRs
