Here’s What You Really Need to Know About That Viral Mask Study "...If you can see through it, air is moving through’s probably time to stop using it as a mask." -Peter DeCarlo

masksMounting evidence suggests coronavirus is airborne. Peter DeCarlo discusses evidence of airborne transmission, particle behavior, risks, and why he added his name to an open letter urging WHO to revise their guidance.

Peter DeCarlo's Research

Human activity and natural processes can have measurable impacts on atmospheric composition and indoor air quality. These emissions can have impacts on the earth’s climate system, outdoor and indoor air quality, and other negative outcomes. An important focus of my research involves the characterization of aerosol particles (also called particulate matter or PM). These particles, 100x smaller than the width of human hair, are damaging to health, have a major impact on the climate, affect visibility, and can damage fragile ecosystems. These detrimental effects are controlled but the concentration, composition, size, and shape of these particles. 

Research Interests

Peter 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.

DeCarlo received his PhD in Atmospheric Science from the University of Colorado and earned a postdoctoral fellowship at the Paul Scherrer Institute in Switzerland and an AAAS Science Policy Fellowship in Washington D.C.
