SIMULATING REGIONAL-SCALE AIR QUALITY WITH DYNAMIC CHANGES IN REGIONAL CLIMATE AND CHEMICAL BOUNDARY CONDITIONS
HOGREFE, C., S.T. RAO, R. BULLOCK, A. GILLILAND, AND P. L. KINNEY. SIMULATING REGIONAL-SCALE AIR QUALITY WITH DYNAMIC CHANGES IN REGIONAL CLIMATE AND CHEMICAL BOUNDARY CONDITIONS. Presented at International Conference on Mesoscale Processes in Atmosphere, Ocean and Environmental Systems (IMPA 2006), New Delhi, INDIA, February 14 - 17, 2006.
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.
This poster compares air quality modeling simulations under current climate and a future (approximately 2050) climate scenario. Differences in predicted ozone episodes and daily average PM2.5 concentrations are presented, along with vertical ozone profiles. Modeling results suggest ozone episode increases in the future, as well as some increases in PM2.5; however, additional years of simulation are needed to more thoroughly test this.
