"WebAlbedo Values See All Cryosphere Mini Lessons. When sunlight reaches the Earth’s surface, some of it is absorbed and some is reflected. The relative amount (ratio) of light that a surface reflects compared to the total incoming sunlight is called albedo. A surface with a high albedo will reflect more sunlight than a surface with low albedo. " - Earth albedo

WebJan 22, 2024 · Like solar radiation in general, albedo values also vary across the globe with latitude but Earth’s average albedo is around 31%. For surfaces between the tropics (23.5°N to 23.5°S) the average albedo is 19-38%. At the poles, it can be as high as 80% in some areas. This is a result of the lower sun angle present at the poles but also the ... WebThe albedo of unvegetated ground devoid of snow ranges from 0.1 to 0.6 (10 to 60 percent), while the albedo of fully forested lands ranges from 0.08 to 0.15. An increase of 0.1 in regional albedo has been associated with a 20 percent decline in rainfall events connected with thunderstorms.
