Snow, ice, and clouds have high albedos (typically from 0.7 to 0.9) and reflect more energy than they absorb. Earthâs average albedo is about 0.3. In other words, about 30 percent of incoming solar radiation is reflected back into space and 70 percent is absorbed. A sensor aboard NASAâs Terra satellite is now collecting detailed measurements of how much sunlight the earthâs surface reflects back up into the atmosphere.
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.
