@xylar You may wait to review until I post a Compass PR for testing these changes |
TestingThis branch has been run on Chrys with intel, open-mpi with the ISOMIP+ Ocean0 test MPAS-Dev/compass#896. The landIceDraft differences from master are consistent with a different ocean density being used in Compass than the namelist default from MALI. The |

There was a problem hiding this comment.
As discussed on Slack, let's maybe move this to a different (new?) namelist section and remove flux from the name.

@xylar I know you're out of the office at the moment. Would you like to look at the simulation results before I migrate to E3SM? |
|
I think you can go ahead and move to E3SM. I'll take a look when I can but it sounds promising from your description. |

Closed in favor of E3SM-Project#7301 |

Formerly,
landIceDraftwas provided along withlandIcePressureas a forcing variable. With this PR,landIceDraftis computed fromlandIcePressureas an ocean diagnostic using a reference ocean density provided as a new config option. In future configurations in which MALI and MPAS-Ocean are coupled, there should be a mechanism for ensuring consistency of this parameter in both components.This PR is non-BFB because land ice draft is used to compute pressure-adjusted SSH from which the coupled variable gradSSH is computed.
