@chengzhuzhang Please let me know if I should change anything here. I think this should be fine to merge. We can test it as part of the next weekly test on main.

I suppose one possible use case not covered by this PR is wanting a different ncclimo on this call than in the first call in this file. I think that's an unlikely use case though.

The code change looks good to me based on visual check.
