  1. “Toward a More Efficient Transboundary Exchange of Air Quality Data” Cliff Michaelsen Maine Rich Poirot Vermont

  2. Acknowledgments Many Thanks to the Following Folks For Their Contributions to This Effort: • Paul Wishinski / State of Vermont DEC • Stefan Falke / CAPITA, Washington Univ. • Brett Schichtel / CAPITA, Washington Univ. • Rudy Husar / CAPITA, Washington Univ. • Jeff Brook / AES, Environment Canada • David Waugh / DOE, AESBED • Steve Beauchamp / DOE, AESBED • Ray Hoff / AES, Environment Canada

  3. Arsenic Episodes of 1989 Ozone Episode of July 1994 Mixed Pollutants In August 1992

  4. Atmospheric Flow Visualization: CAPITA Monte Carlo Model (see Movie: USFLW792.AVI, provided by Brett Schichtel, CAPITA)

  5. Noranda Sudbury HY-SPLIT / NGM Trajectories arriving at 3 PM for Underhill, Vermont Day 1 12/23/89 Yellow Day 2 11/04/89 Green Day 3 2/04/89 Red

  6. Back Trajectories from Ontario Sites on Days with High Arsenic/Selenium Ratios: 1988-92 Provided by Ray Hoff, Atmospheric Environment Service, Environment Canada

  7. Noranda Sudbury HY-SPLIT / NGM Trajectories arriving at 3 AM for Underhill, Vermont Day 1 12/23/89 Yellow Day 2 11/04/89 Green Day 3 2/04/89 Red Day 4 3/22/89 Purple

  8. US/Canadian Data Interface AES Canada Airs (with Voyager) AES Downsview transfers data Into EXCEL Decompile AIRS Data Manipulate in EXCEL Merge in ACCESS Ready to Use Canadian/USA Data Re-compile into a Voyager file

  9. Hourly Ozone and Surface Winds : 7/19-23/94 (see Movie SCOTIA3.AVI)

  10. HY-SPLIT / NGM Trajectories arriving at 9 PM on July 21, 1994 at the following locations: North Cape, PEI Green Acadia NP, Me. Red Cape Elizabeth, Me Purple

  11. HY-SPLIT / NGM Trajectories arriving at 3 PM on July 20, 1994 at the following locations : North Cape, PEI Green Acadia NP, Me. Red Cape Elizabeth, Me Purple

  12. 3 PM Ozone , 24 hour PM-10 and Sulfate on August 28, 1992 (see Movie: PMOZSU92.AVI)

  13. 6 Days earlier, on August 22, 1992, maximum concentrations of afternoon Ozone and daily PM-10 and Sulfate were centered in the Midwestern US

  14. Windsor Fine Particle Mass and Sulfate (blue) Toronto at 4 Canadian Sites on August 23 - 27, 1992 Montreal Data Provided by: Jeff Brook, AES Environment Canada Kejimkujik

  15. Keji Montreal Toronto Windsor HY-SPLIT / NGM Trajectories arriving at 3 PM on the following dates for 4 sites: Red - Windsor 8/23/92 Pink - Toronto 8/24/92 Green - Montreal 8/25/92 Yellow - Keji 8/26/92

  16. Keji Montreal Toronto Windsor HY-SPLIT / NGM Trajectories arriving at 3 PM at the following sites on 08/27/92: Windsor, Ont. Purple Toronto, Ont. Lt. Purple Montreal, Que. Red Kejimkujik, N.S. Green

  17. NEPART Fine Particle Mass, Sulfate and "Acidity" on 8/28/92 with Air Mass Histories from the CAPITA Monte Carlo Model

  18. Conclusions • We Examined 3 Episodes of Transboundary Pollution Transport • Assumed We Understood These Episodes in Advance • Assumed it would be Easy To Merge US & Canadian Data Both Assumptions Were Wrong! We Efficiently Exchange Air Pollution Across our Border, Where it is Merged with Local Source Influences, but is Too Often Unobserved, Undocumented, and Uncontrolled We Need More Efficient Mechanisms to Exchange and Merge our Collective Air Quality Data!
