Dr. John G. Watson is a Research Professor in DRI's Division of Atmospheric Sciences where he has been employed for 40 years. His research includes: 1) evaluating, characterizing, and advancing methods to measure carbonaceous material in suspended particles; 2) developing and applying real-world, multipollutant emission measurement technologies; 3) designing and conducting aerosol characterization and source apportionment studies; and 4) evaluating effects of air contaminants on human exposure, visibility impairment, and material/cultural artifact degradation. Source characterization has emphasized diffuse emitters, such as dust suspended by mechanical and windblown mechanisms, engine exhaust from high emitters, and biomass burning in domestic and wildland settings. His recent projects involved real-world emissions testing in the oil sands region of northern Canada, engine exhaust characterization in Hong Kong, designing air quality measurement networks in developing countries, and commercialization of a multi-wavelength thermal/optical aerosol carbon analyzer. His current efforts are directed at evaluation of microsensor/smartphone interfaces for detecting and remediating fugitive dust emissions and estimating excessive human exposures, determining causes of elements in stormwater runoff, and increasing the efficiency and cost-effectiveness of particulate matter and visibility measurement systems. Dr. Watson has published critical reviews on measurement methods, visibility impairment, and fugitive dust emissions and control.
