This is a wave hindcast for the period 1995 - 2018 covering the North and Baltic Sea. The simulation has been performed with the spectral wave model WAM Version 4.6.2. The model domain covers the area from approx 49.2° N to 66.6° N and 9.8° W to 31.6° E, with a spatial resolution of 0.044 degree latitude x 0.044 degree longitude (approx. 5 by 5 km) on a rotated grid with the coordinates of the rotated north pole 140°W E and 32° N. Integrated parameter derived from 2D spectra are available every hour. Atmospheric forcing was obtained from the COSMO-REA6 regional atmospheric reanalysis (https://rmets.onlinelibrary.wiley.com/doi/abs/10.1002/qj.2486) provided by the German Weather Service (DWD) . Lateral boundary conditions were obtained from corresponding coarse grid hindcast covering most of the Northeast Atlantic driven by the same atmospheric forcing.
