Soot and Sulfate Still Images and Video of Tractor Soot Particle

Aerosols are complex particles; they can occur in nature but can also be generated by humans. Black carbon, or soot, is generated from industrial pollution, traffic, outdoor fires, and household burning of coal and biomass fuels. Soot is a product of incomplete combustion, especially of coal, diesel fuels, biofuels and outdoor biomass burning. When soot absorbs sunlight, it heats the surrounding air and reduces the amount of sunlight reaching the ground. The heated air makes the atmosphere less stable, creating rising air (convection) which forms clouds and brings rainfall to regions that are heavily polluted.
