The Southern Ontario Centre for Atmospheric Aerosol Research (SOCAAR) at the University of Toronto is an interdisciplinary centre for the study of air quality, with a focus on how aerosols impact human health and the environment. SOCAAR brings together medical personnel, atmospheric chemists and environmental engineers, and promotes collaborative research through access to state-of-the-art facilities and partnerships with government and industry.
