Reflection of solar radiation occurs when the radiation is sent directly backward from a surface. The fraction (or percentage) of radiation reflected back is known as albedo. Albedo varies greatly from one location to another on Earth, depending on the type of surface (for example, land or water), the extent of snow or vegetation coverage, …
