Tidal Stream Atlas in netcdf format - Western Brittany

The Tidal stream atlas netcdf product – Western Brittany provides tidal current data for an area stretching from the northern coast of Brittany (Porsguen) to the south of Penmarc'h. The product consists of four gridded files with different spatial resolutions covering the Finistère area (overall view at 500 m) and the geographical areas of the Iroise Sea (250 m), Brest bay (100 m) and Brest harbour (30 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 at the reference port chosen in the area and are provided from 6 hours before to 6 hours after that reference.
