Aerosol particles in the atmosphere are produced both in nature and by people. A global aerosol optical depth of about 0.12 is suggested. These aerosols increase the reflected solar radiation at the top of the atmosphere by about 3 W m −2 globally. Anthropogenic sources contribute significantly to the global aerosol optical depth.
