| Zusammenfassung |
| Air pollution from ships contributes to overall air quality problems and it has direct health
effects on the population in particular in coastal regions, and in harbor cities. In order to
reduce the emissions the International Maritime Organisation (IMO) have tightened the
regulations for air pollution. E.g. Sulfur Emission Control Areas (SECA) have been
introduced where the sulfur content of marine fuel is limited. However, up to now there is no
regular monitoring system available to verify that ships are complying with the new
regulations. Furthermore measurements of reactive trace gases in marine environments are in
general sparse.
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 chemistry of the atmospheric boundary layer
and to establish a monitoring system for main shipping routes. Here we present
MAX-DOAS observations of NO2 and SO2 carried out during ship campaigns in the
North and Baltic Sea and from two permanent sites close to the Elbe river (Wedel,
Germany) and on the island Neuwerk close to the mouths of Elbe and Weser river.
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
and air borne observations (see Kattner et al., Monitoring shipping emissions with
in-situ measurements of trace gases, and Meier et al., Airborne measurements of
NO2 shipping emissions using imaging DOAS) observations. Furthermore simple
approaches have been used to calculate emission factors of NOx and SO2 for single
ships. |
