WebIt’s calculated by averaging the albedo of all Earth surfaces – including the land, ocean, and ice. Above the Earth surface, clouds reflect large amount of sunlight out to space too. Earth's planetary albedo is about 31% meaning that about a third of the solar energy that gets to Earth is reflected out to space. WebIn the above table, we see that the Earth’s average albedo is 0.31, but there is considerable variation in this value over the surface of the Earth and over time as well — this spatial and temporal variation in albedo of …
