Web‘Albedo’ is Latin, meaning whiteness. The albedo ofa surface is the fraction of the incident sunlight that the surface reﬂects. Radiation that is not reﬂected is absorbed by the surface. The absorbed energy raises the surface temperature, evaporates water, melts and sublimates snow and ice, and energizes the turbulent WebAlbedo is a calculation of diffuse solar radiation reflected from the total solar radiation, and it's determined on a range of zero to 1, with 0 corresponding to a black body that absorbs every incident radiation and 1 corresponding to a body that reflects almost every incident radiation.
