On 14 December 2017, a Symposium on 'Climate System Reanalyses for Society' was organized at the University of Bern, as part of the EU-FP7 project ERA-CLIM2 outreach activities. Symposium speakers included representatives from the European Union, the ERA-CLIM2 project and the wider scientific community. A first group of talks focused on the role of reanalyses to monitor and understand the time evolution of the Earth-system climate, and the ongoing work done, e.g., by projects such as ERA-CLIM2, to improve the quality of reanalyses. A second group of talks discussed global activities designed to improve climate services, led by the World Meteorological Organization and European Institutions.
