Dr. Jacques Descloitres is a senior research engineer at the AERIS/ICARE Data and Services Center at University of Lille, France. He has over 25 years of experience in satellite data processing and development of data services. He holds an engineer degree from Ecole Centrale de Lille (1990) and a Ph.D. in Physics for Remote Sensing from the University of Paris 7 (1996). His field of expertise is remote sensing and radiative transfer in the atmosphere. In 1997, he joined University of Maryland and the MODIS Science Team at NASA's Goddard Space Flight Center to work on the quality assurance of the MODIS land products. After joining Sciences Systems and Applications, Inc. (SSAI) in 2000, he co-founded and led NASA's MODIS Rapid Response System, which produced near real-time MODIS fire products and imagery for operational application users and outreach. Dr. Descloitres received several NASA awards for contributions to environmental science and outreach. In 2004, he joined the Centre National de la Recherche Scientifique (CNRS) and was the Director of ICARE Data and Services Center, from its early origins to 2017, leading a team of a dozen engineers to develop a wide suite of data services for the atmosphere. He has been involved in many French and European collaborative projects and major satellite missions. Since 2019, he is involved in algorithm development to detect Sargassum using satellite observations.
