Sentences with phrase «radiation from the surface rather»

Not exact matches

There is an increase rather than a decrease in upwelling radiation, because the radiation is coming from a warmer surface and troposphere.

What maintains the surface temperature is thus not radiation from GH gases, because it would have been hotter without them, rather like the Moon that reaches temperatures around 130C.

«in an isotropic non GHG world, the net would be zero, as the mean conduction flux would equalize, but in our earth it is still nearly zero» if the atmosphere were isothermal at the same temperature as the surface then exactly the downwelling radiation absorbed by the surface would be equal to the radiation of th surface absorbed by the air (or rather by its trace gases) and both numbers would be (1 - 2E3 (t (nu)-RRB--RRB- pi B (nu, T) where t (nu) is the optical thickness, B the Planck function, nu the optical frequency and T the temperature; as the flow from the air absorbed by the surface is equal to the flow from the surface absorbed by the air, the radiative heat transfer is zero between surface and air.

Then, for the benefit of the lay reader, who would not be expected to understand the clear (to a competent physical scientist) implication of this simply - stated fact, I wrote: «This in fact indicates that the Venusian atmosphere is heated mainly by incident infrared [not the VISIBLE portion, which is indeed largely reflected, defenders, but INFRARED] radiation from the Sun, WHICH IS NOT REFLECTED BUT ABSORBED [or allowed in to heat the lower atmosphere] by Venus's clouds, rather than by warming first of the planetary surface.

The result of the radiation partial insulation is to raise the location of radiation to space to a high altitude rather than directly from the surface.
