Mesmart
Mesmart (measurements of shipping emissions in the maritime troposphere) is a research project within the framework of a cooperation between the University of Bremen and the Federal Maritime and Hydrographic Agency .
Among other things, the project measures and monitors emissions from shipping using various methods in order to monitor compliance with exhaust gas regulations , but also to obtain information on the spatial and seasonal distribution of exhaust gas emissions. The results are compared with satellite measurements and passive sampling in order to obtain long-term data for monitoring the SECA zones (Sulfur Emission Control Area) in the North and Baltic Seas. Are recorded SO 2 , NO 2 , NO , CO 2 and O 3
The measurements are carried out "on site" with a trace gas monitor in sucked-in ambient air by deploying on board the research ship Celtic Explorer and at the coastal stations in Neuwerk and Wedel . SO 2 and NO 2 are also measured by optical remote sensing with differential optical absorption spectroscopy (DOAS).
The aims of the project are the analysis of the current pollution situation, the determination of the proportion from ship emissions and the comparison with model estimates. From this, the long-term effects can be estimated and how effective the current and future regulatory provisions are, how compliance with the regulations can be effectively monitored and which measurement methods can be used for this.
