Ozone Episode of July 1994
Mixed Pollutants In August 1992
Notes:
We examine 3 “transboundary” pollution events, with the following objectives:
1. To illustrate that air pollution flows freely in both directions across the US / Canada border (but is not routinely observed, or documented)
2. To emphasize the importance of exchanging and merging our collective air quality data (which typically stops at the border).
1 Arsenic transport from Canada to the Northeast states during 1989,
2. Ozone transport from the Northeast states to the Eastern Provinces during July, 1994,
3. Multiple-pollutant (O3, PM-10, PM-2.5, SO4, H+) transport from Midwestern US to Northeast States and Provinces during August, 1992.
Before we started this effort, we thought:
1. We understood these Episodes (with our limited US data) pretty well,
2. It would be relatively easy to gather and merge some transboundary air quality data.
