These simulations are made for the location of station 271** Central Eastern Gotland Sea of the Baltic Sea** at 20 deg E and 57.3 deg N with a water depth of 250 m. Initial conditions for temperature and salinity are derived from measurements. Meteorological forcing was available from the ERA15 reanalysis data set. For the penetration of solar radiation into the water column, fairly turbid water (Jerlov type IB) is assumed. Salinity concentrations are nudged to observations with a time scale of 50 days.

This plot was created with gotland.py. [/caption] The simulation is carried out for the years 1980-1990. For the discretisation, the water column has been divided into 100 vertical layers, with a strong zooming towards the surface, resulting in a mean near-surface resolution of less than 0.5 m. The time step for these simulations is set to 10 minutes. For details of the gotland scenario see Burchard et al. (2006).
