Xavier Ceamanos

About

Xavier Ceamanos is a leading researcher in satellite remote sensing of aerosols and their impact on the Earth's radiative budget. His work centers on improving the accuracy of aerosol property retrievals and solar radiation estimates, particularly over challenging land surfaces like North Africa. A key contribution is his investigation into how the diurnal variation and chemical composition of aerosols influence direct radiative forcing. In his highly cited 2016 study (45 citations), he demonstrated the critical role of daily aerosol cycles when using MODIS data. His 2015 work (24 citations) advanced the operational Downwelling Surface Shortwave Flux (DSSF) product from LSA-SAF, showing that accounting for aerosol composition—specifically dust and biomass burning particles—is essential for accurate solar radiation estimates over West Africa. Ceamanos also contributed to algorithm development, comparing methods like LABITS and AERUS-GEO for retrieving aerosol optical depth from MSG/SEVIRI data. Through these efforts, he has provided vital insights for climate modeling and solar energy applications, helping to bridge the gap between satellite observations and the complex, variable nature of atmospheric aerosols.
