Source attribution of PM for Berlin using Lotos-Euros
conference paper
Air Quality in Berlin is a problem especially during winter episodes. During such episodes the build-up of pollutants released within the city is just one factor contributing to the high concentrations. During conditions with easterly winds and inversion situations with low planetary boundary layer heights pollutants produced in Eastern Europe are adverted to Berlin. To support the development of the air quality plan for Berlin the origin of the pollution for the annual mean and during episodes is required. To be able to attribute the share of the overall pollution in Berlin for 2014-2017 to its origins the labelling approach incorporated in the Chemistry Transport Model (CTM) LOTOS-EUROS v2.1 is used. During winter episodes agriculture and residential combustion are the most important sectors, each contributing about 30% to PM2.5 mass. Secondary contributions come from industry, energy production and traffic. The latter is the most important local source. Only during the highest episodes the Polish contribution to PM2.5 exceeds that of Germany, whereas the Polish contributions are generally as high as the combined contribution of other eastern European countries. During summer 2018 the model system underestimates the PM10 concentrations due to the large fraction of coarse mode material related to the drought conditions. © 2019 Harmonisation within Atmospheric Dispersion Modelling for Regulatory Purposes, HARMO.
