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.
About 51% of solar energy reaching the earth is absorbed by the Earth's surface. Incoming solar radiation: 100% Reflected by the atmosphere: 6% : Absorbed by â¦ the atmosphere: 16% Continuing incoming solar radiation: 78% Reflected by clouds: 20% : Absorbed by clouds: 3% Continuing incoming solar radiation: 55% Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51% (Source: NASA.)
