WebOf the solar radiation reaching Earth’s surface, some is reflected back into the atmosphere. Values of the surface albedo range as high as 0.95 for fresh snow to 0.10 for dark, organic soils. On land, this reflection occurs entirely at the surface. In water, however, albedo depends on the angle of the Sun’s rays and the depth of the water ... Web3.3 Planetary Albedo Planetary albedo is defined as the fraction of the total incident solar irradiance, S, that is reflected back into space. Radiation balance then requires that the absorbed solar irradiance is given by E = (1 - A) S/4. The factor of one-fourth arises because the cross sectional area of the earth disc to solar radiation,

This means that of … WebJan 26, 2024 · The reflected amount of radiation is called as the albedo of the earth. The value of albedo will be different for different surfaces. Because of the effect of albedo, highly developed areas such as urban cities can experience higher average temperatures than the surrounding suburban or rural areas, a phenomenon known as the “ Urban Heat ... WebJan 1, 2024 · Radiation reflected from the Earth's surface can be rereflected back, and so surface albedo can influence the downward flux. Thus, BOA solar radiation is much less than that at TOA and is commonly divided into two fluxes: direct radiation coming from a 2.5 to 5° angle centered on the sun, and diffuse radiation from the rest of the sky hemisphere. blinman to marree
