Multiple grid masks on same grid?

[tclune]

We have a problem that arises when gridcomps are developed in different institutions. E.g., UFS has added a mask to the grid for land vs ocean using the values "0" and "1". Meanwhile GOCART adds a different mask for emissions - also using "0" and "1". This then becomes an issue when UFS wants to use GOCART - resulting in unintended consequences.

See issue here:

GEOS-ESM/MAPL#3280

We are interested in ESMF core-teams suggestions on how to best coordinate such things.

I should have done a bit more reviewing of the documentation prior to posting the above. I had incorrectly remembered that one could attach multiple masks to a grid.

So I modify my question: How should one coordinate using multiple masks on a grid? The obvious answer would seem to be to set the mask when doing the regrid store and then unset the mask. But that suggests that the mask should just be part of the regrid store command ...

You can set different mask values in the grid and then choose the one that you want to be masked when you do regrid store (via the srcMaskValues or dstMaskValues arguments). Using this you can turn on and off different masks during the regrid store. We can talk about this more on the call.
