100% of the energy entering earthâs atmosphere comes from the sun. ~50% of the incoming energy is absorbed by the earthâs surface i.e. the land and oceans. ~30% is directly reflected back to space by clouds, the earthâs surface and different gases and particles in the atmosphere (the earth's albedo is 0.3 on average). ~20% is absorbed by the atmosphere and clouds. The 70% of the sunâs energy that is absorbed by the earthâs surface, clouds, and atmosphere causes warming. Any object or gas that has a temperature emits radiation outward, and this is ultimately re-radiated back into space.
Further, the processes are exactly the same whether radiation is incoming or outgoing. The sun does radiate in the infrared and CO2 at the top of the atmosphere absorbs and radiates about half of the incoming infrared radiation at frequencies near 700 cm-1back into space. There is also outgoing infrared radiation that is absorbed and re-radiated back to earth.
