The Pentland Firth and Orkney Waters (PFOW) model is an implementation of the Finite Volume Community Ocean Model (FVCOM) and has a domain covering the northern Isles of Orkney and Shetland and Moray Firth, extending from approximately 0° - 5° W and 57° - 61° N. The model is part of the Scottish Shelf Model (SSM) suite of hydrodynamic models and is a downscaling of the wider Scottish Shelf Model. The model grid is unstructured with the highest horizontal resolution in the Pentland Firth where the typical node spacing is 100 – 150 m. Away from Orkney the model has a comparably low horizontal resolution. The vertical water column is resolved using 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.
