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.
1 To be in radiation balance Earth would have to be warmer by about 12C. Clouds cool the planet by reflecting sunlight back into space, much as they chill a summer's day at the beach.  Clouds warm the Earth by absorbing infrared radiation emitted from the surface and reradiating it back down. The process traps heat like a blanket and slows the rate at which the surface can cool. The blanketing effect warms Earth's surface by some 7C.
