what is albedo
Albedo (/Ã¦lËbiËdoÊ/) is the whiteness of a surface. It is a reflection coefficient, and has a value of less than one. Albedo is derived from Latin albedo whiteness (or reflected sunlight) in turn from albus white, is the diffuse reflectivity or reflecting power of a surface. The albedo of a surface is the ratio of radiation reflected from the surface to the incident radiation. Its dimensionless nature lets it be expressed as a percentage and is measured on a scale from zero (no reflection) of a perfectly black surface to 1 for perfect reflection of a white surface.
