Marine Scotland Data Portal

The Scottish Shelf Model (SSM) 3.01 26 Year Reanalysis, otherwise referred to as the Scottish Shelf Waters Reanalysis Service (SSW-RS), is a hindcast model, run from 1993 to 2018, covering the Scottish continental shelf waters as well as most of UK waters, the North Sea and the English Channel. The domain extends from approximately 48° - 62° N and 13° W - 13° E. The SSM 3.01 26 Year Reanalysis was developed and run by the National Oceanography Centre. The model output, which includes hourly horizontal currents and water elevation fields, daily mean fields of three-dimensional currents, temperature and salinity, on the unstructured model mesh, is available for download from Registration is required to access this data via the SSW-RS website:

The SSM implements the Finite Volume Community Ocean Model which utilises an unstructured computational grid enabling the model to resolve many small scale coastal features. The horizontal resolution ranges from 1 km at the coast to 20 km at the outer boundary. The vertical water column is resolved using 20 terrain following sigma layers, each representing 5% of the water column. Products provided by Copernicus Marine Service were used to force the model at open boundaries, to provide sea surface temperature data assimilation and to calibrate/validate the model.
