COVID-19 and Air Quality

Regional Air Quality and Other Information Resources During the COVID-19 Pandemic

With the significant change in air pollutant emissions during the COVID-19 pandemic, there are opportunities to investigate how these changes affect air quality throughout the Ozone Transport Region. To promote collaborative opportunities among the research community and air quality agencies, this webpage provides a listing of on-going and past air quality data measurements and air quality researchers collecting potentially relevant data sets. The focus is on the Ozone Transport Region, but some of the listed resources include national (U.S.) and global data sets. In addition, several links are also included for state-level projections of COVID-19 health metrics and trends in activity levels.
