CAMx Organics
• Primary organic aerosol (POA)– Sources: any combustion– Emitted as a stable aerosol
• No evaporation/re-condensation
• Secondary organic aerosol (SOA)– VOCs oxidize to condensable gases– SOA forms as f(T, RH, aerosol mass)– Condensation/evaporation possible
V:\corporate\marketing\overview.ppt
CAMx Organics
• CAMx treats 5 kinds of SOA– SOA1-3 from anthropogenic VOC
sources• Tracks formation from aromatics and parafins• Combustion and fugitive sources
– SOA4-5 from biogenic VOC • Terpenes generate two SOA products• Less apt to evaporate• Updates coming for both CAMx and CMAQ
– Sesqueterpenes and isoprene
