Measurements of shipping emissions and trends in air quality with different methods — •Barbara Mathieu-Üffing1,2, Lisa Kattner1,2, André Seyler1, Folkard Wittrock1, Andreas Weigelt2, Stefan Schmolke2, and John Burrows1 — 1University of Bremen, Institute of Environmental Physics (IUP), Bremen, Germany — 2Federal Maritime and Hydrographic Agency (BSH), Hamburg, Germany
During the project MeSmarT (Measurement of Shipping Emissions in the Marine Troposphere) the short and long term impact by emissions of nearby passing individual ships on air quality is monitored by in-situ measurements of NO, NO2, O3, SO2 and CO2, by DOAS (Differential Optical Absorption Spectroscopy) measurements and diffusive sampling of NO2 and SO2 at two stations, at river Elbe and at Neuwerk island. At times in parallel AQMesh® sensors were tested for suitability for measuring individual ship’s emissions and air quality trends.
Variations and trends in background concentrations and pollution rate of some trace gases and differences between the two stations can be seen. The comparison of results shows chances and limitations of these methods with aspect to its application in environmental monitoring in atmospheric science and control of regulatory limits, i.e. to the MARPOL regulation of marine fuel sulphur content and its effect on air quality.
