The project MeSMarT (Measurements of shipping emissions in the marine troposphere, www.mesmart.de) has been established as a cooperation between the University of Bremen and the German Bundesamt für Seeschifffahrt und Hydrographie (Federal Maritime and Hydrographic Agency) with support of the Helmholtz Research Centre Geesthacht to estimate the influence of ship emissions on the atmospheric boundary layer and to establish a monitoring system for main shipping routes.
On the 1st of January 2015, the allowed sulfur content of marine fuels inside Sulfur Emission Control Areas (SECA) established by the International Maritime Organisation (IMO) has been significantly decreased from 1.0% to 0.1%.
Here we present MAX-DOAS observations of NO2 and SO2 carried out from two permanent sites close to the Elbe river (Wedel, Germany) and on the island Neuwerk close to the mouths of Elbe and Weser since the year 2013. Mixing ratios of both trace gases have been retrieved using different approaches (pure geometric and taking into account the radiative transfer) and compared to in situ observations. Furthermore, emission factors of NOx and SO2 have been calculated for single ships.
