About
Olivier Geoffroy is a leading researcher in atmospheric physics, with a primary focus on aerosol–radiation interactions and their implications for Earth’s energy budget. His work centers on understanding how aerosol composition, particularly in data-sparse regions, affects the accuracy of satellite-derived estimates of downwelling surface shortwave flux (DSSF). In his highly cited 2015 study, Geoffroy demonstrated that neglecting aerosol composition—especially mineral dust and biomass burning particles—can introduce significant biases in solar radiation estimates over West Africa. Focusing on the Sahelian stations of Dakar and Niamey during the dry season, he showed that accounting for aerosol type improves DSSF retrievals by up to 30 W/m², a critical refinement for the operational products distributed by the Land Surface Analysis Satellite Application Facility (LSA-SAF). With over 24 citations, this work has become a key reference for improving satellite-based radiation products in aerosol-heavy environments. Geoffroy’s research directly supports climate monitoring, solar energy resource assessment, and agricultural planning in vulnerable regions. His contributions exemplify how detailed aerosol characterization can bridge the gap between satellite observations and ground-based reality, advancing both operational remote sensing and fundamental climate science.
