Using an Angstrom pyranometer ( an albedometer) to measure albedo

Using an Angstrom pyranometer ( an albedometer) to measure albedo. 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. In: “Monthly Weather Review,” March 1931, p. 118.
