  1. Aircraft Observations of Siberian Smoke Plumes Transported to the Pacific Northwest Presented by Isaac Bertschi

  2. Overview of Long-Range Transport Studies PHOBEA (1997, 98, 99, 2001, 02) ACE-Asia (2001) PEACE (2002) ITCT (2002) PEM-West A (1991) TRACE-P (2001) CITE-2 (1986) BIBLE (2000) CITE-1 (1983) PEM-West B (1994) MLOPEX (1989, 91, 92)

  3. Airborne Measurement PlatformBeechcraft Duchess 76 • Continuous Measurements • RF-UV CO Analyzer • Integrating Nephelometer • UV Ozone and ECC Instruments • Temp/RH/GPS

  4. Cheeka Peak Observatory48.3 N, 124.6 W, 480 meters (asl)

  5. Synopsis ofSummer 2003 Observations

  6. Synopsis ofSummer 2003 Observations Flights 1 and 2: 27 May and 2 June, 2003 (Julian Days: 148 and 154)

  7. Synopsis ofSummer 2003 Observations Flight 9: 5 August, 2003 (Julian Day: 217)

  8. 2 June Event

  9. 2 June 2003 Event: Fire Detection and Smoke Transport 5/24/2003

  10. 5 August Event

  11. 5 Aug 2003 Event: Fire Detection and Smoke Transport 7/27/2003

  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. 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. • Summer 2005: Summer urban smog study with WSU. • ITCT/PHOBEA Spring 2006. • Airborne measurements of other trace gases (Hg, etc.). Future Research Goals/Work
