Anti-greenhouse effect
The anti-greenhouse effect is a mechanism similar and symmetrical to the greenhouse effect: in the greenhouse effect:the lower atmosphere absorbs thermal radiation while being relatively transparent to sunlight;
is cooler at the top than at the bottom;
consequently emits less thermal radiation at the top of the atmosphere relative to what is emitted by the surface;
which results in the surface being warmer than the effective temperature associated with emissions from the top of the atmosphere.In the anti-greenhouse effect:
an upper layer of the atmosphere absorbs sunlight while being relatively transparent to thermal radiation;
that layer is warmer at the top than at the bottom;
consequently, the net thermal radiation emitted to space is larger than the amount of thermal radiation emitted by lower layers of the atmosphere;
which results in the surface being cooler than it would be if an equal amount of sunlight was absorbed but not by that upper layer.This effect has been discovered to exist on Saturn's moon Titan.
