Please insert here your affiliation logo First author’s name Design Guideline - principles STS 4910TRA2014 Paris 14‒17 avril 2014 Matulla et al.  Internal climate variability: Averaging of climate projection data (periods of 30 y, at least 10 y)  Ensemble building: consider model diversity, many members (enable 15 th /85 th Percentiles)  Downscaling (proposal) = = statistical regionalization + bias correction  Ensemble Approach (make ensemble statistics)  Use preferably simple impact models (otherwise: only a case study may be possible) ……

Please insert here your affiliation logo First author’s name Outlook  Enlarge the region stepwise by consistently including further European countries  Use new scenarios (RCPs of EURO-CORDEX)  Avoid the mixing of datasets  Ensure highest quality of data – no breaks along borders  Include air traffic and railway transport  Expand the analysis to further CIs (e.g. damage of bridges, water to street level) STS 4911TRA2014 Paris 14‒17 avril 2014 Matulla et al.
