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!
