Abstract

From the first photographs taken from V2 rockets in 1948 to recent observations by the EarthCare mission, satellite observation of clouds has undergone spectacular development in terms of spectral, spatial and temporal sampling. These observations enable us to delve deep into the physical processes that govern the life cycle of clouds, to better understand their impact on present and future climate. What are clouds, how do we characterize them, and what do they reveal about the atmosphere ? We'll see how satellites, by observing clouds on different time and space scales, help us to better understand them.

Jérôme Riedi is a professor at the University of Lille, where he conducts research at the Atmospheric Optics Laboratory. D. in Physics and Atmospheric Sciences in 2001, after working on multi-angular polarization measurements for the determination of cloud microphysical properties. In 2001, he joined NASA Goddard Space Flight Center, USA, as a Research Associate, where he contributed to the development of the cloud observation pipeline for the MODIS mission.
In 2003, he moved to the University of Lille as a lecturer, where he became a professor in 2011, and headed the AERIS/ICARE Data and Services Center from 2017 to 2023. His research focuses on atmospheric remote sensing, with a particular interest in the characterization of clouds, aerosols and water vapor, using multiangular and multispectral polarization measurements. Dr Riedi also develops simulation tools for the validation of space observation systems. He is actively involved in several space missions, notably as a member of the principal investigator group for JAXA's SGLI/GCOM-C mission and a member of the joint ESA/EUMETSAT mission group for the 3MI/METOP-SG mission.
