Web1 Jun 2024 · While the snow cover presents a nearly constant extent, the albedo decreased significantly over GR. This reduction may be ascribed to the changing state of the Greenland snow cover and glacier surfaces rather than to a decrease of the effective area that they cover (Box et al., 2012; Tedesco et al., 2016 ).

Web6 Jan 2024 · Nonspherical snow grains show less BC-induced albedo reductions than spheres with the same effective sizes by up to 0.06 at ultraviolet and visible bands. Compared with external mixing, internal mixing enhances snow albedo reduction by a factor of 1.2–2.0 at visible wavelengths depending on BC concentration and snow shape. WebAlbedo effect. Albedo is the ability of a surface to reflect sunlight (solar radiation). Snow and ice have high albedo – much of the sunlight hitting surfaces covered with snow and ice bounces back. In contrast, dark earthy surfaces have a low albedo, therefore, they absorb more sunlight. Thus, the proportion of Earth’s surface that is ...
