Dr Florence Rabier has been the Director-General of ECMWF since January 2016, after two years leading the Centre’s Forecast Department. Her career so far has taken her back and forth between Météo-France and ECMWF. Dr Rabier is an internationally recognised expert in numerical weather prediction, whose leadership has greatly contributed to delivering major operational changes at both ECMWF and Météo-France. She is especially well known within the meteorological community for her key role in implementing an innovative data assimilation method (4D-Var) in 1997, which was a first worldwide and contributed to an optimal use of satellite observations in weather forecasting. She also led an international experiment involving a major field campaign over Antarctica, in the context of the International Polar Year and the WMO THORPEX programme. She has been awarded the title of “Chevalier de la Légion d’Honneur”, one of the highest decorations awarded by the French honours system, and the Great Prize of the Air and Space Academy for the IASI project (Infrared Atmospheric Sounding Interferometer) and its atmospheric and weather applications.
