How do we measure the albedo of objects

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. When talking about … Webmedian point near this albedo. It would also show that only 10% of the objects have an albedo greater than 0.5, and another 4% have an albedo greater than 1.0, including two objects with an albedo just over 80. Since the calculated albedo assumes light is scattered equally in all directions, a calculated albedo greater than 1.0 is possible if ...

Above the Earth surface, clouds reflect large amount of sunlight out to space too. … These calculations are based on the bidirectional reflectance distribution function (BRDF), which describes how the reflectance of a given surface depends on the view angle of the observer and the solar angle. BDRF can facilitate translations of observations of reflectance into albedo.

So, high albedo means that a greater portion of light falling on something is reflected back. This also means a that greater amount of light goes back towards outer space which is then absorbed by the greenhouse gases present in the atmosphere.
