Suspension of particles of condensed matter (liquid, solid, or mixed) ina carrier gas (usually air). Aerosols are important in the atmosphere asnuclei for the condensation of water droplets and ice crystals, asparticipants in various chemical cycles, and as absorbers and scatterersof solar radiation, thereby influencing the radiation budget of theearth-atmosphere system, which in turn influences the climate on thesurface of the Earth.
