WebFresh snow, on the other hand, can have an albedo of 90%, which means that 90% of the sunlight that hits a snow-capped peak is reflected out to space. The amount reflected back out to space is called the planetary albedo. It’s calculated by averaging the albedo of all Earth surfaces – including the land, ocean, and ice.

In blue are the updated albedo anomalies after improved data analysis, which also include more years of data (Palle 2008). Over a five-year period, scientists found that albedo did increase slightly.

WebThe overall albedo of the Earth - measured to be 0.30 - has a significant effect on the temperature of the Earth, as it changes how much solar energy is reflected by the Earth as opposed to how much is absorbed. ... WebOct 24, 2013 · When sunlight reaches the Earth’s surface, some of it is absorbed and some is reflected. The relative amount, or ratio, of light that a surface reflects compared to the total incoming sunlight is called albedo. Surfaces with high albedos include sand, snow and ice, and some urban surfaces, such as concrete. Surfaces with low albedos include forests, …
