Ozone at high elevation in Quebec region

Kurt Anlauf, Kathy Hayden, Maurice Watt

(1)present background ozone concentrations (2) real-time ozone for use in air quality forecasting (3) long-term trend of ozone in Eastern North America

(4) ozone episodes as a result of anthropogenic emissions

(5) the meteorological and chemical processes conducive to the appearance of such episodes

(6) the transboundary flux into southern Quebec.

Current Activities

Future Activities

- site to be added to the AQ forecasting network - install upgraded instrumentation for real time access

- start and complete 2004 O3 and meteorology datasets

- collaborating with S. Oltmans (NOAA) on a paper to assess tropospheric O3 changes

- more detailed NOx emissions (seasonal) – changes in anthropogenic emissions

- continue with trend analysis
