Workshop Objectives & Expected Products

This workshop aims to discuss the current knowledge and uncertainties in quantifying source-receptor relationships for photooxidants and fine particles in North America and Europe, with a focus on the Arctic region. The workshop will also explore research activities and strategies to integrate this knowledge into regional air quality assessments and develop future research recommendations.

  6. What do we know? Can we quantify the source-receptor relationships for photooxidants and fine particles between anthropogenic emissions in North America and Europe and ambient concentrations over the Arctic, North America, and Europe?

  7. If we can quantify the relationships, how do we best integrate this knowledge into our current assessments of regional air quality strategies? What do we need to do?

  8. What do we need to do? What are the key uncertainties in these source-receptor relationships? • Emissions • Entrainment Aloft • Transport Mechanisms • Chemical & Physical Transformations • Deposition • Local Interactions

  9. What research activities could help reduce these uncertainties? How can the various communities represented best address these activities? What do we need to do?
