The combination of long observation-based data like the “Twentieth Century Reanalysis” (20CR, Compo et al. 2011) with a 30 member ensemble of simulations with a state-of-the-art climate climate using historical instrumental observations and climate proxies spanning the last 400 years. The focus lies in the analysis of extreme events (such as storms, heat waves, droughts), associated atmospheric flow features (e.g. blockings, cyclone tracks) and their forcings (e.g. volcanoes, sea surface temperatures, solar activity) with a special focus on inter-decadal variability.
