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. When talking about … WebAlbedos for typical surfaces are given in Table A2. Natural surfaces generally have albedos ranging from 0.05 to 0.30 ( Frank, 1984 ). The most notable exceptions are snow, which, when fresh, can have an albedo of up to 0.95, and thick cloud, which can have an albedo of 0.75 or higher. Any given surface can exhibit substantial variations in albedo.

WebDec 19, 2024 · Glacier surface albedo strongly affects glacier mass balance by controlling the glacier surface energy budget. As an indicator of the equilibrium line altitude (ELA), the glacier snowline altitude (SLA) at the end of the melt season can reflect variations in the glacier mass balance. Therefore, it is extremely crucial to investigate the changes of … WebJan 26, 2015 · Abstract. The fraction of the incoming solar energy scattered by Earth back to space is referred to as the planetary albedo. This reflected energy is a fundamental component of the Earth's energy balance, and the processes that govern its magnitude, distribution, and variability shape Earth's climate and climate change.
