The data are from a multi-decadal tide-surge hindcast 1958-2004 for the North Sea using the TELEMAC2D model. Data (sea surface elevation, depth averaged currents) are available every hour on an unstructured grid with about 27,000 nodes and varying resolution ranging from about 5 km in the open North Sea to about 75m near the coast and within estuarys. The model was driven by hourly atmospheric data from a multi-decadal atmospheric hindcast

and, at the open boundries, by the most relevant tidal constituents. In addition, hourly sea level data from Aberdeen were assimilated at the Northern boundary to account for external surges.
