Dr. Gordon’s research interests are the emission, deposition, and transport of chemicals, pollutants, aerosols, and particles to and from various sources, including petroleum production facilities, road traffic, forests, and arctic environments. Specific current topics include analysis of airborne measurements over the Alberta Oil Sands, the study of aerosol and VOC emissions in a mixed forest at the Borden Forest Research Station, and the mixing and transport of traffic-pollutants on and near highways in the Toronto area. These projects combine field measurements with microscale transport modelling and analysis.
