What is Albedo? My NASA Data

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 albedo, the surface is almost always the surface of a planet like Earth. [2] WebOct 20, 2016 · A 1 means that a material reflects all of the light energy that hits it. In other words, a 1 on the albedo scale means 100 percent reflection. A 0 means no reflection. Fresh asphalt, Flickr. Fresh asphalt, for example, has an albedo of around 0.05, which means that only 5 percent of the light is reflected. The rest—95 percent—is absorbed. schenectady adk newsletterWebFor reference, the values of albedo range from 0.0 to 1.0, where a value of 0.0 is for a surface that absorbs all radiation (reflects 0 percent) that strikes its surface, and a value of 1.0 represents a surface that reflects 100 percent of the radiation that strikes it. Fresh snow has an albedo ranging from 0.75 to 0.90. schenectady adult protective services

WebAlbedo is defined as the percentage of solar (shortwave or ultraviolet) radiation reflected by a given surface. The range of albedo on the Earth's surface can be as little as 3% (0.03) for water and as high as 95% (0.95) for fresh snow cover. Scientists have studied the albedo of the surface vegetation and land cover found on Earth. WebSnow, ice, and clouds have high albedos (typically from 0.7 to 0.9) and reflect more energy than they absorb. Earth’s average albedo is about 0.3.
