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 … WebA refinement we intorduce into our model is to put a temperature dependence on the albedo. The justification for this is that as the temperature of the Earth decreases, more of the water on the planet will freeze, which will increase its albedo (since the albedo of ice is about 0.6 compared to about 0.32 for land).

The average incident solar radiative flux is 341 W m -2, so that a change in albedo of 0.01 represents a global energy balance change of 3.4 W m -2, similar in magnitude to the impact of doubling carbon dioxide in the atmosphere.

WebMay 13, 2011 · The albedo of all these different surfaces combined is called the planetary albedo. Earth's planetary albedo is about 0.31. That means that about a third of the solar energy that gets to Earth is reflected out to space and about two thirds is absorbed. The Moon's albedo is 0.07, meaning that only 7% of the energy that gets to it is reflected. WebJan 26, 2015 · Abstract. The fraction of the incoming solar energy scattered by Earth back to space is referred to as the planetary albedo. This reflected energy is a fundamental component of the Earth's energy balance, and the processes that govern its magnitude, distribution, and variability shape Earth's climate and climate change.
