Workshop on Climate Change and Air Quality: Part I - Intercontinental Transport and Climatic Effects of Pollutants (Dec 3-5, 2001)

To increase awareness and establish a better scientific foundation for addressing linkages between climate change and air pollution and for investigating issues related to intercontinental transport of criteria pollutants, the U.S. EPA Office of Air Quality Planning and Standards (OAQPS) sponsored a workshop titled “Climate Change and Air Quality; Part I: Intercontinental Transport and Climatic Effects of Pollutants.” The MCNC Environmental Modeling Center organized the workshop. It was the first of two back-to-back workshops held jointly with the U.S. EPA Office of Research and Development.*

Goal

The goal of the Part I workshop was to identify near-term research priorities and activities to be pursued to address the impacts of air pollution on climate change. Among the topics of interest were:

· Development and enhancement of regional air quality models and global/regional emission inventories to better represent the connections between global air quality and climate

· Development of nesting capabilities between global chemistry/climate models and regional air quality models

· Evaluation of global and regional air quality models using a diverse set of observational data sets, including data from satellites, surface networks, intensive field studies, etc.

· Simulation of hemispheric or regional air quality for a variety of scenarios addressing future global and regional emissions, air quality, and climate conditions

· Further development and application of global chemistry/climate models that will enhance our understanding of the linkages to regional air quality

The workshop ran from 1:00 p.m. on Monday, December 3, through noon on Wednesday, December 5. It was held on the MCNC campus in Research Triangle Park, North Carolina. The workshop used oral presentations, group discussion, and plenary sessions to categorize and assess models, data, and analysis tools that can be utilized and adopted for evolving studies investigating connections between air pollution, climate, and intercontinental transport.
