Presentation Transcript

  1. Biogenic Aerosol Studies • Smog chamber studies • Aerosol yields (humidity, temperature, seed) • Product identification and quantification (GCMS, LCMS, TDPBMS) • Mechanisms (use gas phase mechanisms to explain products) • Ambient measurements • GCMS of aldehydes and acids in filter samples from forested areas • New particle formation in forests and surf zones • Modeling smog chambers and ambient • Global biogenic SOA, nucleation, growth

  2. Aerosol Yields from Biogenic Organics

  3. OH and O3 Oxidation Patterns for Bicyclic Alkenes

  4. Estimated Species Contributions to Global Emissions Monoterpenes = 127-147 Tg yr-1 ORVOC = 94-260 Tg yr-1 Biogenic Aerosol = 13-24 Tg yr-1

  5. Mechanisn of Cyclohexene + O3 Reaction

  6. Biogenic Aerosol Studies: Future Needs • Smog chamber studies • Aerosol yields (humidity, temperature) • Product identification and quantification (labile and low volatility compounds), vapor pressures and activity coefficients (organic and aqueous solutions) • Mechanisms (include heterogeneous reactions) • Ambient measurements • Identification and quantification, and biogenic marker compounds • New particle analysis
