I specialize in remote sensing of the physical parameters of the atmosphere. My main focus is to characterize atmospheric aerosols (smoke, dust, organic and marine particles) using ground, airborne or satellite sensors. The information I obtain from it is used to validate air quality models and to correct satellite images for atmospheric effects. My most recent research focuses on remote sensing of aerosols in the Arctic (PEARL Observatory in Eureka, Nunavut), on the analysis of pan-Canadian aerosols from the AEROCAN network, jointly managed by Environment Canada and my research team, and finally, on the analysis of Lidar data (Pulse Laser) from the CORAL-Net pan-Canadian network (a CORAL-Net Lidar is part of the equipment that I use).
