Chosen methods

The project builds its information flow on ship traffic data from the HELCOM AIS, emission measurements and air quality monitoring. Using supercomputers, the AIS tera-size dataset is calculated into emissions for each ship, gridded into a regular grid in space and time, and fed to an air quality model. The air quality model estimates the spreading and deposition for the whole Baltic, or even for individual harbours. The modelled air quality is validated with concentration and deposition measurements on both stationary platforms (typical municipal air quality monitoring stations) and on moving platforms (sniffer car and ships). Quality assurance is applied throughout the chain, starting from the emissions.

The solubility and ecological usability of nitrogen is analysed in a laboratory in experiment chambers by introducing exhaust-like gas containing nitrogen in to the water. Computer models are built to recognise ship exhaust emissions’ impact on the marine environment.

The population exposure is modelled in a way that combines air pollution concentrations and the location of the population. The model allows for the exposure e.g. in residences and workplaces. It is possible to evaluate the exposure in different population age groups also (e.g. elderly or children). The computed results are processed and visualised using the GIS system. Exposure data is used to evaluate health effects according to the method used in the EU CAFE (Clean Air For Europe) program.
