Albedo

Albedo is a measure of how much light or radiation is reflected by a surface. It ranges from 0 to 1, where 0 means no reflection (a perfect absorber) and 1 means total reflection (a perfect reflector). Different surfaces have different albedos; for example, fresh snow has a high albedo because it reflects most sunlight, while dark asphalt has a low albedo as it absorbs more heat. Albedo is important in climate science, as it influences temperatures and weather patterns—higher albedo can lead to cooler climates, while lower albedo can contribute to warming.
