In other words, about 30 percent of incoming solar radiation is reflected … WebAlbedo is the measurement of reflectivity of sunlight by any object (Hall and Qu, 2006). Objects reflecting more sunlight have high albedo while those reflecting less have a low albedo. It is measured on a scale of 0–1 or given in percentage with 1 being a perfect reflector (100%) and 0 (0%) absorbing all incoming light.
