Sentences with phrase «atmospheric emissivity»

In 2016 I had another attempt using actual atmospheric emissivity measurements.
This APS docment pays lip service to the consensus by accepting the black body assumption for the surface IR and reducing atmospheric emissivity, but it's still wrong.
i.e. sigma Ts ^ 4 = S (1 - a) / (1 - lambda / 2) where lambda is the atmospheric emissivity, a is the albedo (0.7), S the incident solar flux (340 W / m ^ 2), sigma is the SB coefficient and Ts is the surface temperature (288K).

Not exact matches

The real GHE is the reduction of surface emissivity, also possibly coupled convection as atmospheric GHG thermal - emission Poynting Vectors annihilate the UP PVs in that wavelength interval.
If the atmosphere were then optically thin and had a low emissivity (which I would think is likely unrealistic) then it would have an adiabatic - like lapse rate, but the atmospheric temperature would drop from a surface temperature of 255 K, to even lower temperatures.
CO; 2 Observations of the Infrared Radiative Properties of the Ocean «[I] t is necessary to understand the physical variables contributing to sea surface emitted and reflected radiation to space.The emissivity of the ocean surface varies with view angle and sea state, the reflection of sky radiation also depends on view angle and sea state, and the absorption of atmospheric constituents such as water vapor, aerosols, and subdivisible clouds affect transmittance.»
So Kirchoff's Law NEVER applies to earth atmospheric situations; EMISSIVITY NEVER EQUALS ABSORPTANCE.
