About
Gérard Dedieu is a leading figure in optical remote sensing, whose work has fundamentally advanced the quantitative use of satellite imagery. His primary research focuses on atmospheric correction and aerosol retrieval over land, critical for extracting accurate biophysical data from satellite observations. Dedieu’s most significant contribution is the development of a pioneering multi-temporal and multi-spectral method for estimating Aerosol Optical Thickness (AOT), a cornerstone for the atmospheric correction of high-resolution images from satellites like FormoSat-2, Landsat, VENµS, and Sentinel-2. This work, published in 2015 and cited over 286 times, solved a long-standing challenge by enabling precise correction without requiring dedicated aerosol sensors. By providing a robust, operational algorithm, Dedieu’s research has directly empowered a global community of scientists to conduct reliable time-series analyses of land surface dynamics, from vegetation health to urban change. His achievements have made atmospheric correction a more accessible and accurate step in the remote sensing workflow, solidifying his impact on the field.
