About
Olivier Hagolle is a leading figure in optical remote sensing, whose work has fundamentally advanced the way we observe Earth’s surface from space. His primary research focuses on atmospheric correction—the critical process of removing atmospheric interference from satellite images to reveal true surface properties. Hagolle’s most influential contribution is a multi-temporal, multi-spectral method for estimating aerosol optical thickness (AOT) over land, a technique essential for the accurate atmospheric correction of data from major satellite missions including Landsat, Sentinel-2, and FormoSat-2. This foundational work, cited over 286 times, has become a cornerstone for quantitative, multi-temporal remote sensing applications. He further demonstrated his leadership by co-organizing the ACIX-II Land benchmark, a comprehensive inter-comparison of atmospheric correction processors that provides the community with a rigorous assessment of state-of-the-art methods. Demonstrating remarkable innovation, Hagolle has also pioneered a novel approach to repurpose AERONET sun photometers, creating a low-cost, very-high-resolution network for monitoring vegetation health. Through these achievements, Hagolle has not only solved a core technical challenge but also provided the tools and standards that enable researchers worldwide to reliably track changes in our planet’s land surface.
