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.)

Dear CF board:
I would like to propose the following standard name:
Standard Name: land_surface_skin_temperature
Definition:The surface called "surface" means the lower boundary of
the atmosphere. The land surface skin temperature is the temperature
measured by an infrared radiometer, but measurements from microwave
radiometers operating at GHz wavelengths also exist. It represents the
aggregate temperature of the skin surface where "skin" means the
surface medium viewed by a sensor to a vertical depth of approximately
12 micrometers. Measurements of this quantity are subject to a large
potential diurnal cycle which is primarily due to the balance between
heating during the day by solar radiation and continual cooling from
terrestrial (long-wave) radiation emitted by the skin surface.
Canonical Units:K
NOTE: I modeled this new name & definition from the name/definition
for the current CF name "sea_surface_skin_temperature" in order to
create some consistency between the two names & definitions.
Sincerely,
Jonathan Wrotny
