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%.

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. 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.

WebEarth’s albedo is the fraction of incoming radiation (sunlight) that is reflected into space. The Earth has an average albedo, which describes how much sunlight is reflected on average for the whole planet and the whole year. That value is about 0.3.

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. WebApr 11, 2024 · In this study, we applied the newly-released Global LAnd Surface Satellite (GLASS) products to detect changes in shortwave radiation and albedo for 2003–2024 over China, and quantified their contributions on potential evapotranspiration (PET) which is the upper limit of ET and generally the basis to estimate it.
