note: land is land+ocean floor
todo @hkershaw get_state_meta_data / get_close_state should be checking ocean floor?
This ocean floor check wrong/not needed? https://github.com/NCAR/DART/blob/a85e162288a90da1fc1ed28fa4d80acb1ca80920/models/MOM6/model_mod.f90#L547-L549
I'm not sure what the MOM6 grid looks like:
2D wet/dry sufficient (squishy bottom grid follows ocean basin) vs. 3D wet/dry (grid extends into ocean basin)
https://github.com/NCAR/DART/tree/pert_plus_missing-grid has pert_model_copies & missing grid from #727 so it can run
Perturbing MOM6 to get some ensembles to play with. Currently (lazily) using the default perturbation routine, which perturbs everything in the state including land.
This gives some fuzz on the land:
c.TL319_t232.001
nwa12_test.3_0_a03a
Compare to non-fuzz before perturbation
who cares? You'll inflate the land because mean /= 0 (adds more fuzz), get_close makes 'dry' state far away so the assimilation update doesn't change the land, but still I think dangerous to fuzz. See https://github.com/NCAR/DART/issues/359 for missing_in_state comment
