Albedo is the measure of the fraction of solar energy reflected by the Earth’s surface. Lighter color surfaces reflect light and have a high albedo, while darker surfaces absorb light and have a low albedo. Rapid urbanization has changed land use and surface properties, which has an effect on climate regionally and even globally. CSHub researchers are studying the impact of albedo on climate.
