| Abstract | An appropriate planning of coastal and offshore applications needs the knowledge of various aspects of the wave climate. Statistics of past, present and future wave climate are essential to support the design process of several marine tasks. To ensure a good skill of this wave information long and homogeneous data sets are needed for past conditions and a large ensemble of future wave realizations is necessary to assess the range and uncertainty of possible future wave climate. To fulfill the issues of long consistent time series either observations or model simulations based on reanalyses can be used. Observations which are scare in time often cover only short periods or are not always homogeneous. Simulations have the advantage of being highly resolved in time and space but are limited to the availability of global reanalysis data and the reliability of the used models. The investigation of future wave climate conditions is limited to model simulations and has to rely on the quality of the involved models. A large ensemble including various models (global and regional atmosphere and wave models) and their combinations is needed to account for possible model uncertainties. Further, several emission scenarios accounting for possible future global economy and realizations with different initial conditions or perturbations of the model physics are important to take into account the internal climate variability. Here, a hindcast simulation based on a global reanalysis and a set of climate change scenarios for future wave conditions are presented for the North Sea and the Baltic Sea. Beside these wave datasets, similar model data from regional atmosphere, ocean and water level simulations are stored in a database referred to as coastDat and are available online (more information at http://www.coastdat.de). In the following a brief description of the principal model and experimental setup is given and a few results for past and possible future wave conditions are shown. Finally, some applications of the wave data concerning coastal and offshore issues are shortly metioned. A more detailed description of meteo-marine simulations and their applicaFig. 1.
