Lets set wlat(:)=c0 somewhere in one of the init flux routines. Some compiler checks will gag if an unset variable is passed into a subroutine.

FSDmods have been merged into Icepack. Please update Icepack in this PR and I'll do a final review before merging. I ran these changes with Icepack changes on cheyenne and everything should be working as expected, see CICE-Consortium/Icepack#424. Thanks.

The docs badges on the main pages of both CICE and Icepack are indicating 'failing'

[dabail10]

I have fast-forwarded to CICE main which includes the latest icepack version.

You also need to update Icepack explicitly to include the fsdmods. The current CICE has the latest Icepack prior to the fsdmods, this PR needs to update Icepack to include the fsdmods PR that was merged to Icepack last night.

[dabail10]

Sorry, I was confused about that piece. Just updated to include the latest Icepack.

I checked the code + PR out, compared it to my earlier test sandbox, and everything looks good. Will merge soon unless anyone says wait.
