Director of the Center for the Study and Simulation of Climate at the Regional Scale (ESCER) and professor at UQAM, Jean-Pierre Blanchet is a scientific researcher in the field of physical climatology of high latitudes, particularly focusing on the interactions linking aerosols, clouds, radiation, and precipitation. His background in radiation and climate modeling now concentrates on measurements, data analysis, and the development of instruments using far-infrared radiometry based on new technologies developed by INO in Quebec. He contributes to several space missions targeting climate processes related to aerosols, clouds, and precipitation, including CloudSat/CALIPSO on NASA's A-Train, on the ESA's EarthCARE mission, and as the principal investigator of the NuagIR/TICFIRE instrument, developed at UQAM, for the upcoming major Atmosphere Observing System (AOS) mission in preparation at NASA and the AVENIR/HAWC mission at the ASC.

The physical processes and feedback mechanisms involving clouds and aerosols constitute one of the primary sources of uncertainty in our understanding of the climate system and atmospheric modeling. Clouds and precipitation, by modulating radiation, precipitation, and atmospheric composition, play a crucial role in maintaining the Earth's energy and water balance, as well as the climate. Their significant spatiotemporal variability makes it challenging to observe, predict, and characterize them at the kilometer scale. In collaboration with ASC and INO, UQAM's ESCER Center has developed NuagIR/TICFIRE, an innovative radiometer measuring the extended thermal spectrum in the far infrared, a region previously unobserved for terrestrial emissions from space. Integrated into NASA's Atmosphere Observing System mission and the Canadian AVENIR/HAWC mission, this observatory, consisting of 4 satellites on 2 orbits, aims to provide precise measurements of the atmospheric hydrological cycle and processes responsible for extreme weather events and climate change by the end of this decade.

The presentation will be in French
