Combined Water Vapor, Clouds, & Ozone

We combined the previous three modifications to the reference atmosphere, water vapor and scattered clouds to layer 20 and ozone to layer 2.

The result, shown in the blue plot on the figure below, is closer to (but still higher than) reality than any of the previous modifications to a single layer. The surface temperature is now 57.47oC, still hot.

The resulting lower surface temperature and blockage in layer 20 of both solar and terrestrial radiation has caused the temperature to be lower at most levels. The exception, when compared to the reference atmosphere is level 2, where absorption of solar UV-B heats up that layer. However the temperature of level 2 here is lower than that of the ozone-only (previous) profile, showing that terrestrial heat radiation affects the temperature of even the stratosphere.
