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 O 3 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 + O 3 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
