Air quality and deposition – Norwegian Meteorological Institute
The ’Air quality and deposition’ work package focuses on assessing the effect of ship exhaust gas emissions on air quality and depositions before and after the introduction of SECA regulations in the Baltic Sea in the beginning of 2015. The emission measurements conducted in WP2 as well as modelling will be used to estimate air quality at regional scale in Europe (with focus on the Baltic Sea region) and at urban scale in three port cities: Gothenburg in Sweden, the Tri-City region of Gdansk, Sopot and Gdynia in Poland, and Saint Petersburg in Russia. The model calculations of air pollution from ships at different geographical scales combined with measurements provide gridded results for concentrations and depositions. These results in turn will form the basis for calculations based on future emission scenarios (for the years 2020 and 2030), and for the assessment of health and environmental impacts carried out in WP4.
