Faculty : Prof. Mark Gordon

The Air Pollution Lab at PSE 433 researches new techniques to measure and quantify emissions of pollutants and greenhouse gases.  Current areas of investigation include: emissions and mixing of pollutants from highway traffic; emissions from oil sands production facilities; and the interaction of pollutants with forest environments and mixing within the forest canopy.  The lab works in close collaboration with the Air Quality Research Division (AQRD) of Environment and Climate Change Canada (ECCC) as well as the Centre for Atmospheric Chemistry (CAC) here at York.

We study micro-meteorology, atmospheric turbulence, mixing and dispersion, emissions and deposition.  Measurements are made with sonic anemometers, open and closed path gas analyzers, aerosol spectrometers, and optical methods.  Our instrumentation is used to measure meteorology (winds, temperature, pressure, and humidity), turbulence and fluxes, sub-micron aerosols, particulate matter, CO2, ozone, and solar radiation. Modeling work includes various plume simulations, diffusion models, and a 1-dimensional canopy mixing and chemistry model.  We also do work to further develop the top-down emission rate retrieval algorithm (TERRA), which is used to accurately determine area emission rates based on aircraft, UAV, or on-road vehicle measurements.
