The East Coast of Lewis and Harris (ECLH) model is an implementation of the Finite Volume Community Ocean Model (FVCOM) and has a domain covering the whole of the Outer Hebrides, Skye and the Small Isles, and the north-west coast of Scotland. The model grid is unstructured with the highest horizontal resolution along most of the east coast of Lewis, where the node spacing is as small as 40 m but more typically 100 – 200 m. In the east of the domain, the north-west coast of Scotland, the node spacing is typically around 500 m. At the open boundary, the node spacing is approximately 3 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 ECLH 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)
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.
