Item type:Publication, Investigating air quality in the marine environment of the North and Baltic Sea with MAX-DOAS measurements(2021-01-27); ; ; This thesis presents MAX-DOAS measurements of the air pollutants NO2 and SO2 in the marine environment of the North and Baltic Sea and the surrounding coastal areas. As the first part, the results from more than three years of MAX-DOAS measurements on the island Neuwerk in the German Bight are presented. As the second part, a novel application of an "onion peeling" like approach to MAX-DOAS measurements of shipping emissions on Neuwerk was developed, aiming at investigating the strong horizontal inhomogeneities in NO2 over a shipping lane. In the third part, expanding the research area from the German North Sea coast to the entire greater North Sea area and the German part of the Baltic Sea, shipborne MAX-DOAS measurements for air quality assessment have been performed for the first time on a regular basis in this area on routinely conducted survey cruises in cooperation with the German Federal Maritime and Hydrographic Agency (Bundesamt für Seeschifffahrt und Hydrographie, BSH).doctoral thesis602 380 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Measurements of shipping emissions with in-situ instruments(2019-12-16); ; ; Shipping is a major contributor to pollution in coastal areas and harbour towns. It is a growing industry and only few international regulations control its emissions. This thesis describes the set-up and analysis of in-situ measurements at different locations near the German coast, which are influenced by shipping emissions. It focusses on the analysis of a unique and extensive set of plumes measurements, which have been allocated with individual ships. A total of nearly 5 000 plumes could be analysed, especially with respect to their fuel sulphur content (FSC), based on SO2 measurements, and their NOx emission factors. The studies described in this thesis, which are the first of their kind in Germany in this extent, have laid the foundations for the future operational systems determining the pollution emissions from shipping and assessing their compliance with legislation.doctoral thesis811 472
