WebIf 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. This reflective property results in amplification of the solar forcing of air temperature. 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 great white pyrenees grooming
