St. Magnus Bay, Shetland, Climatology 1.02

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.

The SSM is an implementation of the Finite Volume Community Ocean Model (FVCOM). FVCOM was developed by the University of Massachusetts-Dartmouth, USA, by Chen et al. (2003) and is still actively being developed.

The SMB 1.02 is a full year climatological run, which represents average conditions with a 1993 tidal component. The model is nested within the wider SSM and forced by the wider SSM.

The model forcing is made up of the following:

Boundary conditions: Wider SSM climatology version 2.01 (De Dominicis et al. 2017, De Dominicis et al. 2018)
Atmospheric: ERA-interim (1990-2014) (Dee et al. 2011)
Freshwater input: Grid 2 Grid (1962-2011) climatology obtained from the Centre of Ecology (CEH) (Bell et al. 2007, Cole and Moore 2009)

For a full description of the original development of the ECLH model see Price et al (2016). Although note that the model climatological model forcing is as described above.
