SHYFEM model velocity fields for the Venice Lagoon, link to NetCDF files

The database include the ebb, flood and residual velocity fields obtained by the application of the SHYFEM model to the Venice Lagoon. The water circulation in the Venice Lagoon, induced by tide, wind, and water, heat and salt fluxes, was simulated by the unstructured model SHYFEM applied over a spatial domain that represents the entire Lagoon and its adjacent shore with 144361 triangular elements of variable form and size . The water column is discretized into 22 vertical levels with progressively increasing thickness varying from 1 m for the topmost 16 m to 7 m for the deepest layer of the outer shelf. The model was applied for the year 2014 in a 3-D baroclinic mode using observed forcing and boundary conditions (i.e. wind stress, heat and salt fluxes, precipitation, sea level and freshwater discharge). The residual currents are obtained averaging the modelled currents over the one-year simulation.
By comparing model results with sea level data recorders at 26 gauge stations distributed in the lagoon, we estimated an overall root mean square error of 2.1 cm for the simulated water level.
The components of the 3D velocities are provided for each node of the numerical domain.
