Ground temperature and surface temperature

[nickh07@yahoo_com_au]

Hi, I always understood that TS and TG should be the same over land and that TS simply provided SST's unlike TG. However my TG and TS values differ (slightly) so would someone please be able to explain why this occurs, does TS get calculated at a certain pressure?

Regards,

Tg is the temperature of the topmost soil (or snow, if present) layer.

I believe that Ts over land may equal Tg in areas of no vegetation. But in areas with vegetation it may differ because Ts is defined as the "radiative" sfc temperature.

Talking about temperatures I would like to know if this has any role to play in the global warming problems that the advocates of health are saying. Looks to me there might be some relationship in this so decided to ask here.

Although it has been some time ...

What is the actual output in CLM 4.5 for Surface Temperature in the sense of actual Skin Temperature ?
In the history fields and restart files I can only find Ground Temperature, Soil Temperature, Surface Air Temperature, Vegetation Temperature etc.. which are I guess slightly different.

Thanks!
