he St. Magnus Bay (SMB) model is an implementation of the Finite Volume Community Ocean Model (FVCOM) and has a domain focused on St. Magnus Bay on the west coast of Shetland. The model grid is unstructured with the highest horizontal resolution as small as 15 – 20 m between nodes in Row Sound between the Shetland mainland and the island of Muckle Roe. More typically the node spacing is 50 – 100 m in the Sounds and Voes of this region. The outer open boundary has a node spacing of around 1.2 km. The water column is resolved by 10 terrain following sigma layers, each representing 10% of the water column.

Variables include current velocities, water elevations, temperature and salinity, bed stress magnitude and various turbulence parameters (stored in netCDF format).

The data are from a single climatological year representing an average of the years 1990-2014.
