A silver lining of social distancing and quarantine? Better air quality. As more and more cities across the U.S. clamp down on travel, there have been fewer cars on the road and early reports of improved air quality. 

Johns Hopkins University's environmental health and engineerin expert Pete DeCarlo, can discuss how and to what extent social distancing and quarantine measures affect air pollution.

DeCarlo's research focuses on atmospheric air pollution with applications to ambient air quality, including atmospheric aerosols and emissions from anthropogenic activities including natural gas development. He has published extensively in the areas of atmospheric aerosols (particulate matter), air quality, and climate and performed air quality measurements all over the world, and visited with many Congressional offices to discuss climate change and air quality issues.
