Thanks for the new, DD .. "Albedo (/æl'bi?do?/), or reflection coefficient, derived from Latin albedo "whiteness" (or reflected
sunlight) in turn from albus "white," is the diffuse reflectivity or reflecting power of a surface. It is the ratio of reflected
radiation from the surface to incident radiation upon it. Its dimensionless nature lets it be expressed as a percentage and
is measured on a scale from zero for no reflection of a perfectly black surface to 1 for perfect reflection of a white surface."
