Albedo

The proportions of solar radiation reflected by a surface or object, expressed in percentage. Snow-covered surfaces have high albedo level; ground (soil) albedo can be high or low; vegetation-covered surfaces and oceans have low albedo level. The Earth’s albedo varies mainly due to the different levels of clouds, snow, ice, vegetation, and changes in the earth’s surface.
