Description of the service

The Scottish Shelf Waters Reanalysis Service (SSW-RS) provides a 26-year physical reanalysis of the Scottish Shelf Model. This is a downstream service of the Copernicus Marine Environment Monitoring Service, also called the Copernicus Marine Service. The Scottish Shelf Waters Reanalysis Service provides hindcast model runs from 1993 to 2018 including hourly horizontal currents and water elevation fields and daily mean fields of three-dimensional currents, temperature and salinity on the unstructured model mesh. Current users of the service include Scottish public bodies responsible for marine environmental regulation, industry and academia.

The Scottish Shelf Model

The Scottish Shelf Model is a hydrodynamic model covering the Scottish continental shelf waters. The Scottish Shelf Model 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. To find out more about the Scottish Shelf Model please visit the Scottish Shelf Model website.

Copernicus Marine Environment Monitoring Service Products

The Scottish Shelf Waters Reanalysis Service is forced, at the open boundary, with products from the Copernicus Marine Service:

The service uses data assimilation also provided by the Copernicus Marine Service products:

Copernicus Marine Service data are used in addition to open boundary forcing and sea surface temperature data assimilation, for calibration and validation of this service:
