WebAlbedo can be expressed as a percentage (albedo multiplied by 100) that for some is easier to understand. For instance, grass has an albedo of about .23. This means that of the incoming solar radiation that strikes the grass, 23% of it is reflected away. WebEarth's Planetary Albedo Percentage Earth reflects 32% of sunlight directly back to space. Venus' Planetary Albedo Percentage Venus has an albedo of 75% Moon's Planetary Albedo Percentage The moon has an albedo of 7% and has no clouds. True

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 … Webenergy retained by the Earth is strongly dependant on the albedo of Earth surfaces. Just as some clouds reflect solar energy into space, so do light-colored land surfaces. Scientists use the term albedo to define the percentage of solar energy reflected back by a surface.

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.
