WebThe albedo of a surface is a measure of its reflectivity to solar radiation (Paterson, 1994 ). If the albedo of a surface is high, more radiation will be reflected than if the albedo is low. Hence, the average albedo of the planet dictates the levels of solar radiation held and reflected at its surface. Fresh snow has a particularly high albedo. WebMay 13, 2009 · COMPARISONS By the current definition, cool-roof materials have two important surface properties: a high solar reflectance, or albedo, and high thermal emittance. Solar reflectance is the percentage of solar energy that is reflected by a surface. Emittance is defined as the percentage of thermal energy a material can radiate after it is …

Add a comment. 14. tl,dr: low albedo = warming (more energy absorbed); high albedo = cooling (more energy reflected). In principle, and grossly simplifying, energy from the sun warms the ground and less the air. The overlying air is then warmed by the ground, leading to convection, pressure differences, and all that.
