I would argue that if we use a simple radiative model with a variety of assumptions, no upper atmosphere cooling but only warming will occur with increased CO2 (see # 333), based on the radiative transfer equations and the Second Law of thermodynamics, but when other complexities are introduced, this might change.

Studies have shown that these radiative transfer models match up with the observed increase in energy reaching the Earth's surface with very good accuracy (Puckrin 2004).

This remains to be seen, of course, but it's important to point out that the trospospheric amplification prediction does not originate in the models but in the basic physics of radiative transfer in combination with the Clausius - Clapeyron relationship describing the change in atmospheric water vapor as a function of temperature.

The SASBE could, for example, be used to constrain a radiative transfer model to provide top - of - the - atmosphere radiances with traceable uncertainty estimates.

I thought that in the adiabatic case (in order to mirror the atmosphere) there is nil radiative or conductive heat flow.That is the standard atmosphere model where conduction is very small compared with other energy transfers.

On the other side, Professor Andr e Berger and colleagues developed a mathematical model of the climate system, rated today as a «model of intermediate complexity» [6, 7] to solve the dynamics of the atmosphere and ice sheets on a spatial grid of 19 × 5 elements, with a reasonably extensive treatment of the shortwave and longwave radiative transfers in the atmosphere.

It's also the case that the results for the radiative transfer equations will have a certain amount of error using «band models» compared with the «line by line» (LBL) codes for all trace gases.

The reason this warms the surface is most easily understood by starting with a simplified model of a purely radiative greenhouse effect that ignores energy transfer in the atmosphere by convection (sensible heat transport) and by the evaporation and condensation of water vapor (latent heat transport).

From there via radiative transfer model and assuming known lapse rate, we'll get to the surface and obtain F = h (R, θ, φ)-RSB- with h some other function depending on g (note that h, so F depends also on the choice of R e.g the choice where the atmosphere «stops») Last step is just to differentiate F because we need dF in the second integral.
