Anthropogenic Influences on Organic Aerosol Formation and Regional Climate Implications

  • EPA awarded 14 grants in 2013 to improve understanding of the linkages between gas phase chemistry and secondary organic formation and the interaction of anthropogenic and biogenic emissions. Specifically, these projects use field measurements to further understand the extent to which people influence both the homogenous and heterogeneous processes contributing to organic aerosols from multiple sources within the multipollutant mixture. This is improving understanding of important chemical mechanisms and climatic properties of organic aerosol.
