Background and Motivation [2] Black carbon is emitted in a variety of combustion processes and is found throughout the Earth system. Black carbon has a unique and important role in the Earth’s climate system because it absorbs solar radiation, influences cloud processes, and alters the melting of snow and ice cover.

Black carbon consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is emitted in both anthropogenic and naturally occurring soot. Black carbon causes human morbidity and premature mortality. In climatology, black carbon is a climate forcing agent.
