WebAug 30, 2007 · the ground – albedo. The average albedo of our planet is around 0,3: it means that 30 per cent of the sunlight that reaches the Earth is reemitted to the space. The albedo of the Earth surface is nearly dark in the UVB part of the spectrum with values typically between 3 and 5%. So a very small component of the UV radiation is reflected … 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.
