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. WebAlbedo (sometimes referred to as 'reflection coefficient') is a measure of how reflective a surface is.
