WebFor example, the albedo for fresh snow can be as high as .87 (87% of incoming solar energy is reflected). When the portion of ocean and land that is covered by ice and snow increases, the increased area of high albedo can be a positive feedback that increases cooling and expands the area covered with ice WebAlbedo is the amount of sunlight (solar radiation) reflected by a surface, and is usually expressed as a percentage or a decimal value, with 1 being a perfect reflector and 0 absorbing all incoming light.

WebApr 6, 2024 · The microstructure of the uppermost portions of a melting Arctic sea ice cover has a disproportionately large influence on how incident sunlight is reflected and absorbed in the ice/ocean system. The surface scattering layer (SSL) effectively backscatters solar radiation and keeps the surface albedo of melting ice relatively high compared to ice …

Albedo is not directly dependent on illumination because changing the amount of incoming light proportionally changes the amount of reflected light, except in circumstances where a change in illumination induces a change in the Earth's surface at that location (e.g. through melting of reflective ice). That said, albedo and illumination both vary by latitude. Albedo is highest near the poles and lo… harold maldonado rochester nyWebThe albedo of a surface is a measure of its reflectivity to solar radiation (Paterson, 1994 ).
