Tidal Stream Atlas in netcdf format - Seine Bay

The Tidal stream atlas netcdf product – Seine Bay provides tidal current data for an area stretching from Fecamp at the east of the area to Cherbourg at the west. The product consists of two gridded files with different spatial resolutions covering the Seine Bay area (overall view at 500 m) and the geographical area of Le Havre harbour (250 m). The U and V velocities of the tidal currents depend on the tidal conditions considered at mean neap and spring tidal rates. The data are provided in m/s for the surface layer. The times are given in relation to high tide or low tide at the reference port chosen in the area and are provided from 6 hours before to 6 hours after that reference.

Statement

The Tidal stream atlas netcdf product – Seine Bay is the result of using a high-resolution hydrodynamic model implemented by Shom in the Seine Bay.

For an average neap tide and spring tide with tidal coefficients of 45 and 95 respectively, it contains numerical data of surface tidal currents over a tidal cycle sampled every 5 minutes. The product, provided on a regular grid, is available in netcdf-CF format at different resolutions (500 m and 250 m) and on different areas (Seine Bay, zoom on Le Havre harbour).
