What is the planet’s albedo?
The average albedo of the Earth from the upper atmosphere, its planetary albedo, is 30–35% because of cloud cover, but widely varies locally across the surface because of different geological and environmental features.

The average albedo of the Earth from the upper atmosphere, its planetary albedo, is 30–35% because of cloud cover, but widely varies locally across the surface because of different geological and environmental features. Terrestrial albedo. Surface Typical albedo Fresh snow 0.80 Click to see full answer. Considering this, how do you calculate albedo of a planet? Scientists use the term albedo to describe how much light a planet or surface reflects away. E = total energy intercepted (technically, energy flux = energy per unit time, in watts) KS = solar insolation (“solar constant”) = 1,361 watts per square meter. RE = radius of Earth = 6,371 km = 6,371,000 meters. Likewise, which planet has the highest albedo? Venus Also asked, what is albedo and why is it important? Albedo is the reflectivity of a surface. A surface that has a high albedo reflects a lot of solar radiation from the sun back into the atmosphere, whilst a surface that has a low albedo reflects little solar radiation, absorbing it instead.What is the major contributor to Earth’s albedo?The vast majority of the observed global average planetary albedo (88%) is due to atmospheric reflection. Surface reflection makes a relatively small contribution to planetary albedo because the atmosphere attenuates the surface contribution to planetary albedo by a factor of approximately 3.
