WebThe albedo of a surface is a measure of its reflectivity to solar radiation (Paterson, 1994 ). If the albedo of a surface is high, more radiation will be reflected than if the albedo is low. Hence, the average albedo of the planet dictates the levels of solar radiation held and reflected at its surface. Fresh snow has a particularly high albedo.
