Earth's albedo is approximately

WebJan 14, 2009 · Globally, over the course of the year, the Earth system—land surfaces, oceans, and atmosphere—absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). The absorbed sunlight drives photosynthesis, fuels evaporation, melts snow and ice, and warms the Earth system. WebEarth's planetary albedo is about 31% meaning that about a third of the solar energy that gets to Earth is reflected out to space. Why do we care what happens to sunlight that gets to Earth? Understanding how much energy from the Sun is reflected back out to space and how much is absorbed becoming heat is important for understanding climate.

WebAlbedo is a non-dimensional, unitless quantity that indicates how well a surface reflects solar energy. Albedo varies between 0 and 1. Albedo commonly refers to the "whiteness" of a surface, with 0 meaning black and 1 meaning white. A value of 0 means the surface is a "perfect absorber" that absorbs all incoming energy.

WebWhile Moore (1976) reported that previous studies obtained albedo ranges for pine forests of 0.08 to 0.29 and grassland albedo ranges of 0.21 to 0.29, Moore’s own study of albedo across different land covers in Australia found that forests had an average albedo ranging from 0.11±0.04 to 0.116±0.010 during the winter and spring while grasslands … WebIntroduction: The albedo of an object is a measure of how strongly it reflects light from radiant sources such as the sun. Albedo is the percentage of incoming light that is reflected rather than absorbed. It is thought that the earth’s average albedo is around 30%. Energy in the form of visible radiation (light) from the sun warms the earth.

WebAlbedo is a quantitative measure that varies between 0 (a perfect absorber) and 1 (a perfect reflector). When we average the albedo across all of Earth's surfaces, we get the Earth's planetary albedo, which is 0.3. This means that on average, the Earth's surface reflects 30% of the incoming shortwave radiation it receives.
