Dear Jonathan W.
If I recall correctly, surface_temperature means "sea surface
temperature" over the ocean and "skin" temperature over land. In models
I think it is the temperature used in radiation calculations
(emissivity*sigma* surf. temp**4). How would
"land_surface_skin_temperature" differ from land "surface_temperature"?
(note that there is also a standard name for "surface_air_temperature"
which is the air temperature typically 2 m above the surface.)
