WebAug 22, 2016 · Albedo (noun, “Al-BEE-doh”) This is a measure — usually a ratio or percentage — of how much radiation, or light, falling onto an object will be reflected off it. Usually, albedo refers to the amount of sunlight that an object bounces back into space. Light-colored objects — such as snow, fluffy clouds or white t-shirts — reflect a ...

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. dangers of too much flax seedThese 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.
