Earth albedo
WebMar 1, 2015 · The fraction of the incoming solar energy scattered by Earth back to space is referred to as the planetary albedo. This reflected energy is a fundamental component of the Earth's energy balance ... WebMay 6, 2005 · Measurements from space since the 1970s give a global annual Earth albedo of ∼0.29. The average incident solar radiative flux is 341 W m -2, so that a change in albedo of 0.01 represents a global energy balance change of 3.4 W m -2, similar in magnitude to the impact of doubling carbon dioxide in the atmosphere.

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 … WebThe albedo of unvegetated ground devoid of snow ranges from 0.1 to 0.6 (10 to 60 percent), while the albedo of fully forested lands ranges from 0.08 to 0.15. An increase of 0.1 in regional albedo has been associated with a 20 percent decline in rainfall events connected with thunderstorms.
