Addressing climate change with satellites: Canada will contribute to NASA's international Atmosphere Observing System; StFX researcher part of project

The Honourable François-Philippe Champagne, Minister of Innovation, Science and Industry, announced today, Oct. 18th, that Canada will contribute to the Atmosphere Observing System (AOS) mission led by NASA. Canada's contribution is estimated at more than $200 million. Currently slated to launch in 2028 and 2031, this major multi-satellite mission will improve extreme weather prediction, climate modelling, and monitoring of disasters.

A StFX researcher, Dr. Hugo Beltrami, Canada Research Chair in Climate Dynamics and a professor in the StFX Department of Earth Sciences, is part of this project which includes a Canadian university consortium of 13 universities across the country.  

Extreme weather events are increasing in frequency and intensity. The dynamics of our planet's atmosphere are changing. We need better environmental prediction to support adaptation and climate resilience. The AOS, including its Canadian contribution, will measure aerosols and clouds, and how they interact to impact Earth's weather and climate.

Canada's contribution to the AOS is the High-altitude Aerosols, Water vapour and Clouds (HAWC) mission. It consists of two Canadian instruments on a Canadian satellite and a third instrument on a NASA satellite, all planned for launch in 2031. These innovative instruments will provide critical data, enabling Canadian climate scientists and weather forecasters to better understand and predict extreme events, like severe storms, floods, droughts and poor air quality conditions. HAWC and AOS data will be fully accessible.

Thanks to early investments from the Canadian Space Agency in concept studies and technology development for these instruments, Canada was well positioned to take part in this important climate science mission. Canadian collaborators in the HAWC mission include a coast-to-coast consortium of universities, Environment and Climate Change Canada, Natural Resources Canada and the National Research Council of Canada.

Canada's contribution to the AOS mission supports the implementation of Resourceful, Resilient, Ready: Canada's Strategy for Satellite Earth Observation, which describes how Canada will take full advantage of the unique vantage point of space to address climate change and other key challenges of our time.

"Canada has always played a key role in international space programs, helping to find solutions to global challenges. Today's more than $200 million announcement builds on those successes with our participation in NASA's AOS program. It also speaks to our commitment to harnessing science and research to address climate change, natural disasters, and other issues that are important to Canadians," says Minister Champagne.  

"Satellites give us a valuable view of earth; from space we can observe and monitor the weather and our changing climate. The instruments Canada are providing toward this mission will take measurements that are important to understanding weather and climate change, while providing data that will be used by our meteorologists and scientists to enhance predictions and improve our weather, air quality, and climate models,” says the Honourable Steven Guilbeault, Minister of Environment and Climate Change.
Led by NASA, the AOS team includes the Canadian Space Agency, JAXA (Japan), CNES (France) and DLR (Germany).

The Canadian university consortium includes 13 universities across the country: University of Saskatchewan, University of Toronto, Université du Québec à Montréal, McGill University, 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.
