A major funding announcement by the Government of Canada recently set in motion a new era of climate science, and a researcher at the University of Waterloo is a member of the group of scientists at the heart of the initiative.
The High-altitude Aerosols, Water Vapour and Clouds (HAWC) mission received $200 million of funding to create transformative new satellite instruments for measuring changes in the atmosphere.
HAWC is directly supported through the Canadian Space Agency (CSA) and will undertake a mission expected to last some 12 to 15 years.
The CSA mission contributes three instruments and a satellite as part of the international NASA-led Atmosphere Observing System (AOS).
The University of Waterloo is among the top institutions in the country that will participate and produce cutting-edge research to improve our understanding of global climate change.
“This is generation defining for Canadian climate and atmospheric science,” says Dr. Chris Fletcher, professor of geography and environmental management. “The last time a fully Canadian-designed and made instrument launched was in 2003, with the SCISAT mission.”
Fletcher specializes in earth system modelling. His research incorporates insights from computer science to create climate models. Along with his involvement through HAWC, he is a member of the modelling working group for the AOS science team.
“The scale of the project is huge, and it’s likely not to launch until 2030. Once it’s up there, it can be expected to give us data for at least five years and hopefully much longer,” he says. “The way these missions go, you don’t wait until 2030 to say, ‘okay, this is what data we need.’ You use this time to figure out all those details so when the mission launches you are ready to make the most of the time you have.”
Fletcher says that HAWC is going to give scientists a whole new set of tools to better understand what is happening in the atmosphere and the climate system. Its primary function, according to Fletcher, is consistent monitoring and measurements, and especially of places that pose difficulties for gathering accurate data.
“HAWC is going to allow us to monitor areas in Canada’s far north, and also up in the high atmosphere,” Fletcher continues. “This country is so vast that it’s a real challenge to be able to get precise data from remote regions. That’s what this mission is going to do.”
Through HAWC’s enhanced monitoring capabilities, Fletcher says that another major benefit of the project is that it will be possible to better understand atmospheric processes and build better capacity for predictions of climate impacts 50 or even 100 years in the future.
“It’s a whole new generation of scientists that are going to be involved in the development of the mission and in the analysis of the data,” Fletcher says. “For a university like Waterloo and for a researcher like me, there’s a great opportunity to help shape that next generation and give them the tools to better deal with climate change.”

Clear warning signs of potential threats to our environment and wellbeing
Researchers are developing a deep learning algorithm that could act as an early warning system against runaway climate change.
The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Office of Indigenous Relations.
