WebEarth's planetary albedo is about 31% meaning that about a third of the solar energy that gets to Earth is reflected out to space. Why do we care what happens to sunlight that gets to Earth? Understanding how much energy from the Sun is reflected back out to space and how much is absorbed becoming heat is important for understanding climate. WebDec 22, 2005 · The albedo of dark-coloured, wet, and very rough soils ranges between 0.05 and 0.15, while the albedo of light-coloured, dry, and smooth soils varies between 0.35 and 0.40 (Dobos 2006; Oke 1992 ...

WebAlbedo is a quantitative measure that varies between 0 (a perfect absorber) and 1 (a perfect reflector). When we average the albedo across all of Earth's surfaces, we get the Earth's planetary albedo, which is 0.3. This means that on average, the Earth's surface reflects 30% of the incoming shortwave radiation it receives. WebAlbedo is the fraction of incoming sunlight that our planet reflects back to space.
