Short summary
Sea salt emissions were updated to be dependent on salinity which improved sodium predictions in the Baltic Sea region. The impact of sea salt on atmospheric nitrate and ammonium concentrations and on nitrogen deposition in the North and Baltic Sea region is assessed. Sea salt has a low effect on nitrate concentrations but does not improve them. 3 to 7 % of the nitrogen deposition into the North Sea is accounted to the presence of sea salt. In the Baltic Sea, the contribution is negligible.
