This data set contains an event set of over 790,000 high impact European windstorms from six seasonal hindcast ensemble suites, representative of about 19,500 model years. These tracks are produced based on the objective tracking as created by Leckebusch et al. (2008) under the approach pioneered by Osinski et al. (2016) for pure ensemble system or UNSEEN events (Thompson et al., 2017). Details on the event-based tracking and the respectively introduced objective storm severity index (SSI) can be found in Leckebusch et al. (2008). Details on the pure ensembles or UNSEEN approach can be found in Osinski et al. (2016) and Thompson et al. (2017).
