WebFeb 21, 2024 · Description. Albedo is the fraction of incoming solar energy that is reflected back to space by the Earth system (atmosphere, ocean, land surfaces). Bright, white surfaces such as clouds and snow, have high albedos that approach 1.0. Dark surfaces, such as the ocean have low albedos. Albedo is critical for Earth's energy balance and … The average albedo of the Earth from the upper atmosphere, its planetary albedo, is 30–35% because of cloud cover, but widely varies locally across the surface because of different geological and environmental features. The term albedo was introduced into optics by Johann Heinrich Lambert in his 1760 work … See more Albedo is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a … See more Illumination Albedo is not directly dependent on illumination because changing the amount of incoming light proportionally changes the amount of … See more • Cool roof • Daisyworld • Emissivity • Exitance See more Any albedo in visible light falls within a range of about 0.9 for fresh snow to about 0.04 for charcoal, one of the darkest substances.
