An Angstrom pyranometer, used to measure albebo. Albedo is the ratio of the amount of electromagnetic radiation reflected by a body to the amount incident upon it, commonly expressed as a percentage. Ice has a very high albedo while dark surfaces have low albedo. The measuring element is to the left.
