Dear all,
I think the common meaning of "land" in climate models and in
climate observations distinguishes "terrestrial" regions from
"marine" regions. Thus, we have terrestrial plants, terrestrial
water storage, terrestrial water fluxes, terrestrial glaci
"Land surface skin temperature" and "sea surface skin temperature" are
commonly used for MODIS/VIIRS, "surface skin temperature" is commonly used
for AIRS.
I think MODIS/VIIRS have separate groups of people handling "land" and
"sea". "Land" is the domain of the the land science group and "sea" is
Jim,
We're only half disagreeing. When there is a lake (or ice/snow?) on top of
the land, you are talking about the radiative surface at the bottom of the
atmosphere, not the top of the dirt. If I understand correctly, you only
make a special case for designated oceans.
So a more precise name m

Evan,I'm afraid I have to disagree. I'm working with the MODIS and VIIRS Land Surface Temperature products right now, and they are attempting to report the temperatures of the soil/rock/plants/water/etc themselves. The sea surface is masked off, but temperature for water such as lakes and rivers
The rewording specifies that puddles are "land". What about ponds?

What if we have a grid square that is 50% land at 310 K and 50% ocean at 290 K?
Would it be correct to have these two variables associated with it:

Dear CF community:

Dear all,
O.K. I withdraw my suggestion to deprecate sea_surface_skin_temperature.
I do think the definitions should say how skin temperature differs from
surface temperature. Maybe someone can explain that in a few words.
As I understand it, temperature is only defined when molecules are

Dear Karl
Like Roy, I don't think we should deprecate sea_surface_skin_temperature.
Although I cannot remember the arguments - which must be apparent in the
mailing list archive - I do recall that it was a careful and long discussion
with Craig which led to the introduction of the various SST name

Dear Jonathan Gregory,

I now better understand the meaning of the "surface_temperature"
standard name with the temperature defined by heat fluxes at an
interface, and not based on an actual medium.

It is physically meaningful to have a temperature which doesn't relate to any
