Atmospheric aerosols: Biogeochemical sources and role in atmospheric chemistry
@article{Andreae1997AtmosphericAB, title={Atmospheric aerosols: Biogeochemical sources and role in atmospheric chemistry}, author={Meinrat O. Andreae and Paul J. Crutzen}, journal={Science}, year={1997}, volume={276}, pages={1052-1058} }
Atmospheric aerosols play important roles in climate and atmospheric chemistry: They scatter sunlight, provide condensation nuclei for cloud droplets, and participate in heterogeneous chemical reactions. Two important aerosol species, sulfate and organic particles, have large natural biogenic sources that depend in a highly complex fashion on environmental and ecological parameters and therefore are prone to influence by global change. Reactions in and on sea-salt aerosol particles may have a…
