The preparation of the TICFIRE instrument continues as it gears up for deployment in orbit on a satellite as part of the HAWC-Future project. The operation is scheduled to take place in 2032. “Before launching instruments in orbit, they must be tested on the ground and on planes in order to verify the functioning of all the components of the apparatus,” underlines the professor of the Department of Earth Sciences and the atmosphere Jean-Pierre Blanchet, who heads the ESCER center.

From January 7 to February 14, his team participated in the Whafffers Airborne Measures campaign, which took place at the National Research Council of Canada site in Ottawa, Ontario, and at the Gault nature reserve in Mont-Saint-Hilaire, Quebec. This campaign is the result of an international collaboration between UQAM and McGill University, Imperial College London (ICL), the National Research Council of Italy (CNR), the National Research Council of Canada (CNRC), the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), and Climate Change Canada (ECCC).

The postdoctoral trainee Raphaël Peroni participated in several of the flights from the Whafffers campaign with the Far Infrared Radiometer Model 2 instrument (Firr-2), which gives very similar measures to the TICFIRE which should be on the satellite in 2032. “All these measures are important before taking off the rocket that NASA will use to put this satellite in orbit,” specifies Jean-Pierre Blanchet.

The HAWC-Avenir system, made up of innovative sensors designed and largely developed at UQAM and the University of Saskatchewan, is the Canadian contribution proposed for the future AOS satellite mission-Atmosphere Observing System-NASA, specifies the researcher.

HAWC is the abbreviation of High-Altitude, Aerosol, Water Vapor and Clouds. In English, we are talking about the future system for aerosols, water vapor, clouds and their interactions with radiation. The TICFire instrument (Thin Ice Clouds and Far Infrared Emissions), on which Jean-Pierre Blanchet has worked since 2006, is used to measure the changes in the water vapor cycle, including the formation of precipitation, the composition of clouds and thermal radiation responsible for the greenhouse effect. “The HAWC-Avenir system includes several satellites on two orbits, largely covering Canada, Quebec and Arctic,” explains the professor. It will provide essential measures to improve our forecasting models and climate models to better manage weather and climatic hazards.

On January 31, Professor Blanchet’s team was able to visit the CNRC site in order to observe the research planes and the instruments on board the Convir-580, a device dedicated to environmental research. Then, on February 12, the research teams were able to visit the installations of the building system of earth observation (EOS) of the Gault nature reserve of McGill University.

Thanks to funding from the Canadian Space Agency for the HAWC project and other sums obtained last year from the Canadian Foundation for Innovation, UQAM prepares servers and codes to receive part of the data provided by TICFIRE in real time as well as that from other instruments, including Ali (Aerosol Limb Imager) and Show (Spatial Heterodyne Observations of Water), which will be installed aboard a satellite which will follow the same orbit. A project to follow!

Recent Developments and Practical Applications

The HAWC-Future project is a testament to the growing importance of international collaboration in space research. The TICFIRE instrument, with its focus on far-infrared emissions, is crucial for understanding the Earth’s energy balance and climate dynamics. This data will be invaluable for scientists and policymakers alike, providing insights into how changes in water vapor and cloud composition affect weather patterns and climate change.

The collaboration between NASA and Canadian institutions underscores the global effort to monitor and mitigate the impacts of climate change. The data collected by TICFIRE and other instruments will help refine climate models, leading to more accurate predictions and better preparedness for extreme weather events. For instance, improved understanding of cloud formation and precipitation patterns can aid in disaster management, such as predicting and mitigating the impacts of hurricanes and floods, which are increasingly common in the U.S.

Furthermore, the technology developed for the HAWC-Avenir system has practical applications beyond climate research. The sensors and instruments can be adapted for various environmental monitoring tasks, such as air quality assessment and pollution tracking. This cross-disciplinary approach not only advances scientific knowledge but also contributes to public health and environmental sustainability.

One of the key challenges in climate research is the integration of data from multiple sources. The HAWC-Avenir system aims to address this by providing a comprehensive dataset that covers a wide range of atmospheric parameters. This holistic approach will enable scientists to develop more accurate models and simulations, ultimately leading to better climate policies and strategies.

However, some critics argue that the high cost and complexity of space missions may not justify the benefits. While it’s true that these projects require significant investment, the long-term benefits in terms of scientific knowledge, technological advancements, and environmental monitoring are substantial. The data collected will inform policy decisions, enhance public safety, and contribute to a better understanding of our planet’s climate dynamics.

Future Prospects

The successful deployment of the TICFIRE instrument in 2032 will mark a significant milestone in climate research. The data collected will provide unprecedented insights into the Earth’s atmosphere, helping scientists to better understand and predict climate change. The collaboration between NASA, Canadian institutions, and other international partners ensures that this project will have a global impact, benefiting not only the scientific community but also the general public.

As we look to the future, the HAWC-Avenir system and similar projects will continue to play a crucial role in our understanding of the Earth’s climate. The data collected will inform policy decisions, enhance public safety, and contribute to a more sustainable future. The collaboration between NASA and Canadian institutions serves as a model for international cooperation in space research, highlighting the importance of working together to address global challenges.
