GILLILAND, A. CLIMATE IMPACTS ON REGIONAL AIR QUALITY (CIRAQ): MODELING OZONE SENSITIVITIES TO FUTURE CLIMATE. Presented at Assessment of the Impact of Global Change on U.S. Air Quality Workshop, Durham, NC, November 01 - 02, 2006.
Impact/Purpose:
The objective of this work is to investigate the impact of global climate change on the regional air quality of the United States. Impacts of climate change on meteorological patterns and primary source emissions are investigated as primary elements influencing future air quality.
Description:
Using global and regional modeling tools, predictions of future climate and ozone concentrations are developed for the continental United States. Results suggest that future changes in climate will contribute to an increase in ozone concentrations; however, the future changes in air quality emissions could have a much larger effect. The challenge here is that the future emissions scenarios are so uncertain that the impact from future emissions of NOx and VOC could lead to an increase or a decrease in ozone.
