where are the lowest albedos on earth found
Albedo Any albedo in visible light falls within a range of about 0.9 for fresh snow to about 0.04 for charcoal, one of the darkest substances. Deeply shadowed cavities can achieve an effective albedo approaching the zero of a black body. When seen from a distance, the ocean surface has a low albedo, as do most forests, whereas desert areas have some of the highest albedos among landforms. Most land areas are in an albedo range of 0.1 to 0.4.[10] The average albedo of Earth is about 0.3.[11] This is far higher than for the ocean primarily because of the contribution of clouds.
Death Valley The lowest temperature recorded at Greenland Ranch was 15 °F (−9 °C) in January 1913.[20]
