Abstract: Urban areas exhibit a variable land surface temperature … Web22 de jan. de 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 …
