Question about correct skin_temperature CCPP name

[svahl991]

During the JCSDA JEDI variable naming sprint, we added variables to JEDI called:

skin_temperature_at_surface_where_sea
skin_temperature_at_surface_where_land
skin_temperature_at_surface_where_ice
skin_temperature_at_surface_where_snow

I was going to submit a PR to add these names to CCPP, but I do not see that CCPP names ever use the _where_ preposition. I see _in_ and I see _over_. Sometimes both in the same name, as in temperature_in_surface_snow_at_surface_adjacent_layer_over_ice.

So I'm not sure what the "correct" CCPP names should be for the four variables we added. e.g.
skin_temperature_in_surface_sea?
skin_temperature_at_surface_in_sea?

Is there a problem with using _over_ here? Different meaning?

Yes, different meaning. With ..._where_sea for example we're looking for the temperature within the ocean, not the temperature of the atmosphere above the ocean.

_over_ does not mean above. Over stands for the type of the area, for example in the context of a fractional landmask where a grid cell contains areas that are over ocean and areas over land. The over stands for exactly the same thing that you are trying to describe with where.

Since there has been no more discussion on this I'll submit the PR with over, since that is the CCPP standard, and given @climbfuji 's explanation of its meaning. Although I will say that if that is the intended meaning, then where seems more intuitive to me, and doesn't hold the same possibility of being misunderstood as meaning "above", as we did.
