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.

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, WebSep 6, 2013 · Reflecting on Earth’s albedo. 06/09/2013 29909 views 90 likes. ... Bright snow and ice have a high albedo, meaning they reflect solar radiation back into space, …
WebLike solar radiation in general, albedo values also vary across the globe with latitude but Earth’s average albedo is around 31%. For surfaces between the tropics (23.5°N to … WebIn general, most scientists believe that an increase in thin cloud cover would cause warming because thin clouds are very good at trapping surface radiation, but have a relatively low albedo. An increase in thick cloud cover, however, would greatly increase Earth's albedo and cause overall cooling. The process of "trapping radiation," called ...
WebA perfectly black surface has an albedo of 0 (all radiation is absorbed). A perfectly white surface has an albedo of 1.0 (all radiation is reflected).

WebAlbedo can be expressed as a percentage (albedo multiplied by 100) that for some is easier to understand. For instance, grass has an albedo of about .23. This means that of the incoming solar radiation that strikes the grass, 23% of it is reflected away. On the other hand, highly reflective surfaces like snow have an albedo
