12. Pollutant Enhancements during the 2003 Case Studies:

13. GEOS-CHEM
Mean enhancements in CO and O3 surface concentrations from 1 June – 31 Aug due to 2003 Siberian fires.

14. Ozone Observations in the Puget Sound Region
PSCAA Observations at Enumclaw, WA

15. Aerosol Observations in the Puget Sound Region

16. Future Research Goals/Work
Conclusions
From May - August 2003, biomass burning in the Asian boreal zone was a major source of the LRT events observed in the NE Pacific troposphere.
Under certain circumstances, Siberian fire emissions can be a significant source of elevated O3, CO and aerosols in western North America.
