IMPACTS OF CLIMATE-INDUCED CHANGES IN EXTREME EVENTS ON OZONE AND PARTICULATE MATTER AIR QUALITY
Impact/Purpose:
This study aims at improving our understanding and quantification of the potential effects of climate change on extreme meteorological events and air quality. Climate-induced changes in the following extreme events and their consequences for ozone and particulate matter (PM) air quality will be investigated: (a) heat waves; (b) temperature inversion; (c) atmospheric stagnation; (d) lightning activities and associated wildfires.
Description:
Historical data records of air pollution meteorology from multiple datasets will be compiled and analyzed to identify possible trends in extreme events. Changes in climate and air quality between 2010 and 2050 will be simulated with a suite of models. The consequential effects on ozone and PM air quality associated with any long-term changes in extreme events will be evaluated. This project represents the first-ever attempt to examine and quantify the potential impacts on air quality from possible climate-induced changes in temperature inversion, heat waves, emissions associated with lightning and lightning-caused wildfires.
