Albedo geographie definition
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 body that reflects all incident radiation. Surface albedo is defined as the ratio of radiosity Je to the irradiance Ee (flux pe… WebAlbedo is the integrated product of incident solar radiation spectral composition and the spectral reflectivity of the object. Outside the atmosphere, solar radiation spectral composition is relatively constant, peaking at about 0.5 µm, decreasing rapidly at shorter wavelengths to small amounts at 0.2µm, and decreasing less rapidly at longer …

WebThe albedo of an object is the extent to which it diffusely reflects light from the Sun. Reflected heat, in the form of long-wave radiation, is trapped in our atmosphere and … WebThe ground albedo is defined as the ratio between downward irradiance and upward irradiance where the latter results from the diffuse reflectance of the Earth's surface. The ground albedo is generally wavelength dependent and varies with the type of surface. Vegetation strongly absorbs UV radiation.
