Julien Chimot (1985) is a remote sensing scientist with specific interest in atmospheric trace gas, aerosol, cloud and surface observations from satellites 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, spectral signature analysis, use of radiative transfer modelling from the visible to the thermal infrared, broad range of atmospheric retrieval techniques (e.g. Optimal Estimation Methodology – OEM, Differential Optical Absorption Spectroscopy – DOAS and machine learning), and error estimation.
He received his Master specialized in Atmosphere, Ocean, and Environment monitoring in 2008 at the University Paul Sabatier in Toulouse, France. From 2008 to 2013, as R&D engineer, project manager & group coordinator for NOVELTIS (scientific R&D engineering company, Earth space-borne observations, ~50 employees, Labege Innopole, France), he was involved in a variety of 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 trace gas (e.g. CO2, CH4, & H2O) and temperature retrievals. He also contributed to some activities covering altimeter, and ocean colour topics.
Since 2013, he is based at the Geoscience and Remote Sensing department of Delft University of Technology (TU Delft), in the Netherlands. In close collaboration with the Royal Netherlands Meteorological Institute (KNMI), he works on tropospheric NO2, cloud and aerosol retrieval from OMI, in combination with MODIS and CALIOP instruments (doctoral degree to be awarded in 2018). His innovative research has led to a machine learning algorithm for aerosol layer height determination, from the OMI O2-O2 Visible absorption band and an improved correction of aerosol radiation effects in the OMI tropospheric NO2 product.
Julien Chimot (co-)authored 6 publications in international and peer-reviewed scientific journals, 3 European final project reports, and about 12 oral presentations at international conferences and final European project meetings.
Through his multi-experienced profile combining Small and Medium Enterprise and academy / research institutes and his multiple responsibilities, 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.
