How do we measure albedo

WebMeasuring Albedo with a Field Spectroradiometer Albedo depends on the spectral and angular distributions of the incident light, which are governed by atmospheric composition, the direction of the beam of light from the sun and the composition of the surface. WebAlbedometers are instruments that measure global and reflected solar radiation, and the solar albedo. An albedometer is composed of two pyranometers with thermopile sensors; …

WebAn important property of a planet is its albedo . This is the fraction of sunlight reflected from the surface, relative to the amount striking the surface: A = amount reflected / amount incident A perfectly reflective planet would have an Albedo of 1, while a completely black planet would have an albedo of 0. WebAlbedo is the amount of sunlight ( solar radiation) reflected by a surface, and is usually expressed as a percentage or a decimal value, with 1 being a perfect reflector and 0 absorbing all incoming light.
