Polar Environment Atmospheric Research Laboratory (PEARL)

The Polar Environment Atmospheric Research Laboratory (PEARL) is a world-class High Arctic research facility providing U of T-led ground-based observation of the atmosphere from the surface to the lower thermosphere. Established in 2005 and operated by the Canadian Network for the Detection of Atmospheric Change (CANDAC), PEARL serves as an international flagship observatory supporting long-term atmospheric and climate research. Its sustained measurement programs generate high-quality datasets used by university and government researchers to advance climate modeling, ozone chemistry research and Arctic environmental monitoring.
