Earth albedo irradiance

WebJan 1, 2011 · 2.1 Earth Radiation Models. The irradiance received by an artificial satellite, due to the Earth’s reflected (visible) and emitted (infrared) radiation, is calculated by introducing three main assumptions: the Earth behaves like a Lambertian sphere, the radiation is reflected or emitted at its surface and there is a global conservation of … WebSolar irradiance is the amount of solar radiation received on a unit area of the Earth’s surface. It is a critical parameter for understanding the Earth’s energy balance, which is essential for predicting climate changes on a global scale. Solar irradiance plays a significant role in driving the Earth’s temperature and weather patterns.

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. http://bbso.njit.edu/Research/EarthShine/literature/Qiu_etal_2003_JGR.pdf
