Marine Scotland is the custodian of a hydrodynamic model of Scottish continental shelf waters, the Scottish Shelf Model (SSM). The wider Scottish Shelf model (SSM) domain covers the Scottish continental shelf at relatively high resolution (up to 1 km node spacing at the coastline) but also covers most of UK waters, the North Sea and the English Channel. The domain extends in longitude from approximately 13° W to 13° E, including the Baltic Sea. The Wider SSM version 2.01 is a full year climatological run, which represents average conditions for 1990-2014 with a 1993 tidal component.

These data are a reduced precision dataset containing only water elevations and depth average horizontal water velocities on the unstructured grid at hourly temporal resolution.
