WebAn albedo of 1 would mean a perfect reflector and an albedo of 0 would absorb all light striking it. Albedo 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. easy good soup recipe

WebEquation [33] shows that any decrease in planetary albedo, A, from its current value of ~ 0.3 would help to warm the early Earth. Rosing et al. (2010) suggested that Earth's albedo was lower during the Archean because there were fewer cloud condensation nuclei (CCNs) in the atmosphere. WebSince a fraction of the solar radiation is immediately reflected and scattered back out into space-- this is what we call the albedo-- we have to correct the amount of radiation …

WebAlbedos for typical surfaces are given in Table A2. Natural surfaces generally have albedos ranging from 0.05 to 0.30 ( Frank, 1984 ). The most notable exceptions are snow, which, when fresh, can have an albedo of up to 0.95, and thick cloud, which can have an albedo of 0.75 or higher. Any given surface can exhibit substantial variations in albedo.
