Who am I?

My name is Julien Chimot (1985). I am a PhD remote sensing scientist with special interest and 10 years of experiences in atmospheric composition (trace gas, aerosol, cloud) and surface satellite observations for air quality and climate purposes. My 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.

I received my Master degree 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, I 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. I also covered altimeter, and ocean colour topics.

From 2013 to 2018, I collaborated with the Delft University of Technology, and the Royal Netherlands Meteorological Institute (KNMI). As research fellow PhD, I 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. I also contributed to improve the aerosol correction in the operational OMI tropospheric NO2 (a key gas in air quality) retrieval chain. Since 2018, I work at the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), based in Germany, and lead the scientific developments of Near-Real Time (NRT) retrieval of atmospheric composition products from the Copernicus Sentinel-3 mission.

In my career, I have (co-)authored 8 publications in international and peer-reviewed scientific journals, 3 European final project reports, 1 PhD research book, and several technical reports. I have given 16 oral and poster presentations at international conferences and final European project meetings. I also submitted project proposals to French & European space agencies, and the Dutch research funding agency. Through my multiple responsibilities in the context of Small and Medium Enterprise, academy / research institute and international space agency, I 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.
