Physical Scientist - Study Leader - Aerosol chemical and optical properties specialist including black carbon.
CURRENT S&T / RESEARCH - Coordinating and Managing Canadian Aerosol Baseline Measurement program and related research activities
- Changes in physical and chemical properties of aerosols at five Canadian sites to examine the impact of changes in emissions and climate in the Northern Hemisphere
- Changes in atmospheric aerosol composition in the Arctic, and related ice-core snow pack studies in conjunction to the atmospheric concentrations of sulphate, nitrate, black carbon and methane sulphonate
- Changes in aerosols properties due to change in fire activities in the Canadian Boreal region
- Biogenic sulphur emissions in the Arctic
- Changes in aerosol properties due to increase in ship's emissions in the Arctic in near future.
