Great progress has been made in achieving national air quality standards, which EPA originally established in 1971 and updates periodically based on the latest science. One sign of this progress is that visible air pollution is less frequent and widespread than it was in the 1970s. However, air pollution persists in certain environmental conditions and can harm public health. To deal with this, our research group are focusing on:Â
Characterize atmospheric aerosols at different locations in the Northeastern US (including urban, forest, and mountain areas) and the aerosol evolutions under a variety of atmospheric conditions (including extreme weather, fog, and cloud, etc.).
The interplay between the urban outflow plumes and the small scale/local meteorology (i.e., sea breeze circulation)
CH4 emissions from different sources (i.e., landfills, wastewater treat plant, etc.)
Long-term air pollution trends responding to emission controls
