The impact of ship traffic emissions in the Baltic Sea on deposition and airborne concentrations of nitrogen and sulphur compounds in the period 2008--2011 was studied using the Hilatar chemistry transport model with a 0.068° latitude-longitude resolution. An accurate ship emission inventory based on AIS (automatic identification system) security signals was used. The uncertainty of the European emission inventories are discussed, as is an inter-comparison of the Baltic Sea airborne load and concentrations with other model-based estimates and with air quality measurements and the effect of the EU sulphur directive for ship emissions on sulphate concentrations.
