WebMar 5, 2024 · Albedo ranges from 0 (absorbs all radiation) to 1 (reflects all radiation). The higher the albedo, the more it reflects. This is sometimes represented in terms of percentages, from 0% to 100%. WebThe word “albedo” is derived from the Latin word for “white,” and indicates the “whiteness” of the surface doing the reflecting.

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, WebApr 5, 2024 · B. Short Wavelength Solar Radiation Reflected from the Earth. Reflected short wavelength radiation (SW) is a direct measurement of short wavelength radiative flux reflected from the Earth's surface. Unlike albedo, this is an absolute measurement and not a ratio. Thus, the albedo can be where the actual reflected radiation is low.
