Senior scientist
Back to all chairs and co-chairs

Dr. Léonard Rivier is a senior scientist at LSCE: Laboratoire des Sciences du Climat et de l’Environnement in France. After a PhD in 2001 at Columbia University, New York, USA, he started is scientific career in atmospheric transport modelling and greenhouse gases surface flux inversion. Over time, his work moved towards atmospheric GHG observation (metrology, data processing). He is been involved in the construction of the European research infrastructure ICOS, now an ESFRI landmark, since the beginning of its preparatory phase in 2008. ICOS, short for the Integrated Carbon Observation System, is operating an in-situ distributed network of measuring stations producing high-precision data on greenhouse gases. He is now the ICOS Atmospheric Thematic Center Director in charge of the ICOS atmosphere data processing and the metrology of the measurements. He is also member of the ICOS Research Infrastructure Committee, the executive board of ICOS and the ICOS French focal point. He has been involved in many EU projects, some directly in link with COPERNICUS.
