WebReflection of sunlight from solid particles in the atmosphere and from the Earth's surface forms one of the most important controls on Earth's average temperature and on …

WebThe proportion of incoming solar radiation that is reflected by the Earth is known as its albedo. Overall, Earth reflects about 29% of the incoming solar radiation, and therefore, …

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. high reps or high weightWebAlbedo can be expressed as a percentage (albedo multiplied by 100) that for some is easier to understand. For instance, grass has an albedo of about .23.
