The Government of Canada has contributed over $200M into the High-altitude Aerosols, Water vapour and Clouds (HAWC) satellite system, which is a part of NASA’s Atmosphere Observing System (AOS) mission. HAWC will focus on the prediction and mitigation of extreme weather events, and will provide data that will help scientists and policymakers make decisions to prepare Canada for extreme events caused by climate change. Four institutions are co-leading HAWC: the University of Toronto, University of Saskatchewan, Université du Québec à Montréal, and McGill University. Other contributors include the University of New Brunswick, Université de Sherbrooke, University of Waterloo, Wilfrid Laurier University, St Francis Xavier University, Saint Mary’s University, University of Victoria, Western University, and Dalhousie University.
