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. WebAlbedo, as defined as “the fraction of solar energy reflected” (Earth & Space Research (ESR)). As a dimensionless exponent, it can be expressed as both a simple number and percentage figure.
