Urban and Regional Air Quality

Urban and Regional Air Quality

ETA research in this area focuses on regional air quality issues, including:

  • Nitrogen oxides (NOx) and volatile organic compounds (VOCs): controlling them to manage tropospheric ozone pollution
  • Hazardous air pollutants: using science to base standards on rigorously studied risks
  • Air quality and climate: how climate influences air quality at a regional or local level

ETA researchers model ozone, particulate matter and air toxics at the urban and regional scales using state-of-the-art meteorology and chemical transport models at high resolution. They devise modeling diagnostic tools to analyze model performance and the relationship among emissions, meteorology and air quality that are particularly useful in determining how pollutant loading may be reduced to better protect human and environmental health. Researchers also perform modeling to achieve top-down emission inventories of greenhouse gases and to explore the impacts of new energy technologies that have reduced carbon footprints.
