albedo
or surface reflectivity is the ratio of the amount of electromagnetic radiation reflected by a body (surface) to the amount incident upon it, commonly expressed as a percentage. Ice may reflect up to 90 percent of incoming solar radiation (albedo = 90), while blacktop asphalt may absorb up to 95 percent (albedo = 5).
