Julien Chimot (1985) is a remote sensing scientist with specific interest in atmospheric composition (trace gas, aerosol, cloud) and surface satellite observations for air quality and climate purposes. His scientific skills cover big data processing, advanced knowledge of multi and hyper-spectral measurements from passive remote sensors, use of radiative transfer modelling from the visible to the thermal infrared, broad range of atmospheric retrieval techniques, (Optimal Estimation Methodology, Differential Optical Absorption Spectroscopy and machine learning), and error estimation.
He received his Master specialized in Atmosphere, Ocean, and Environment monitoring in 2008 from the Paul Sabatier University in Toulouse, France. From 2008 to 2013, as R&D engineer and project manager for the French NOVELTIS company, he was involved in projects fund by space agencies (e.g. CNES, ESA, EUMETSAT) related to atmospheric infrared satellite missions (IASI, MTG-IRS, GOSAT, Sentinel-5-UVNS, MicroCarb and CarbonSat), with a focus on greenhouse gas (e.g. CO2, CH4) and temperature retrievals. He also covered altimeter, and ocean colour topics.
From 2013 to 2018, he collaborated with the Delft University of Technology, and the Royal Netherlands Meteorological Institute (KNMI). As research fellow PhD, he developed a novel machine learning algorithm for determining the height of atmospheric aerosol from the Dutch-Finnish OMI satellite measurement, in the visible spectral wavelength. He also contributed to improve the aerosol correction in the operational OMI tropospheric NO2 (a key gas in air quality) retrieval chain. Since 2018, he works with the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), based in Germany, and leads the scientific developments of atmospheric composition products from the Copernicus Sentinel-3 mission.
Julien Chimot has (co-)authored 8 publications in international and peer-reviewed scientific journals, 3 European final project reports, and 1 PhD book. He has given 13 oral and poster presentations at international conferences and final European project meetings. Through his multiple responsibilities in the context of Small and Medium Enterprise, academy / research institute and international space agency, he acquired a wide range of competences between Earth Observation research achievement, project management, oral communication, writing, collaboration with scientific partners, student teaching and supervision, autonomy and successful team work as well.
