About
Jean-Claude Roger is a leading figure in satellite remote sensing, whose career has been defined by making Earth observation data usable for science. His primary research focuses on atmospheric correction—the critical process of removing the distorting effects of the atmosphere from satellite images to reveal true surface properties. Roger’s foundational 1997 paper on the atmospheric correction algorithm for NASA’s MODIS instrument, cited over 579 times, provided the operational backbone for global land surface studies, enabling the derivation of biophysical parameters from space. He has also made significant contributions to aerosol science, notably co-authoring a 2008 validation study of AERONET’s solar flux estimates, which has garnered 152 citations and strengthened confidence in aerosol radiative forcing measurements. More recently, Roger led the ACIX-II Land initiative, a major international benchmark exercise that rigorously assessed atmospheric correction processors for Landsat 8 and Sentinel-2, setting a new standard for accuracy in the field. His work on developing aerosol models from the AERONET database further supports surface reflectance validation. Through these efforts, Jean-Claude Roger has provided the global remote sensing community with the tools and confidence needed to monitor our changing planet.
