what is an albedo
Main Image: Albedo is the part of solar energy, the short wave radiation, reflected from the Earth back into the space. The albedo of an object is a measure of how strongly it reflects light from sources like the sun. If an object reflects most of the light that hits it, it appears bright and it has a high albedo. If an object absorbs most of the light that hits it, it looks dark and has low albedo. Darker bodies generally have a lower reflectivity value. Albedo is a term used in reflectivity.
