Title: New Sensors for large-scale air quality monitoring

Speaker: Suresh Dhaniyala, Bayard D. Clarkson Distinguished Professor of Mechanical and Aeronautical Engineering, Clarkson University

Abstract: An important air quality parameter, from a human health perspective, is the mass concentration of particles smaller than 2.5μm, i.e. PM2.5.  The importance of this air quality parameter for human health was first established from a series of epidemiological studies in the US and Europe in 1990s and subsequently ,PM2.5 has become globally accepted as one of the critical measures of air pollution. Conventional PM2.5 monitoring by national agencies has been based on techniques focused on accuracy of mass measurements rather than convenience of deployment. With the need for high temporal- and spatial-resolution of air quality data for health effect studies, newer measurement technologies are increasingly being explored and deployed.

In this talk, I will provide an overview of the currently available low-cost monitoring technologies and their advantages and limitations. I will then introduce our efforts to develop a new low-cost aerosol monitoring instrument based on electrical-mobility technique for real-time monitoring of particle size, number ,and mass concentrations over abroad diameter range of 10 nm to 2.5 μm. The combination of existing and emerging low-cost monitoring sensors will help improve our understanding of health effects of aerosol particles and result in the evolution of more locally-appropriate air quality parameters.
