An open European offshore wind turbine database for mesoscale modelling of European offshore wind farms is presented, containing all operating wind farms as of commissioning date before August 2025. The approach integrates turbine locations from the OpenStreetMap [1] and EMODnet [2] with metadata on turbine and wind farm properties from additional public sources. The turbine information is augmented with generic thrust and power curves calculated via the pyWake [3] turbine generator [4]. References[1] OpenStreetMap contributors (2025).
