Any albedo in visible light falls within a range of about 0.9 for fresh snow to about 0.04 for charcoal, one of the darkest substances. Deeply shadowed cavities can achieve an effective albedo approaching the zero of a black body. When seen from a distance, the ocean surface has a low albedo, as do most forests, whereas desert areas have some of the highest albedos among landf… WebThe albedo of Earth’s surface varies from about 0.1 for the oceans to 0.6–0.9 for ice and clouds—meaning that clouds, snow, and ice are good radiation reflectors while liquid water is not. This is because clouds, snow, and ice have multiple layers that reflect radiation, whereas a body of water reflects only from its surface.
