What is mesmart?

The project mesmart (Measurements of shipping emissions in the marine troposphere) has been established as a cooperation between the University of Bremen and the German Bundesamt für Seeschifffahrt und Hydrographie (Federal Maritime and Hydrographic Agency) to estimate the influence of ship emissions on the chemistry of the atmospheric boundary layer. It aims to monitor background concentration as well as elevated signals of gases and particles related to ship emissions with various methods to cover a wide range of relevant pollutants and their spatial and seasonal distribution. SO2, NO2, NO, CO2, and O3 are measured with in-situ techniques, SO2 and NO2 as well by remote sensing applying the DOAS-technique from ground, ship and airplanes. The data will be compared with satellite measurements and passive sampling in order to find a method to observe the long-term effect of regulations like SECA. High volume filter samples are taken and analysed especially for sulphate, nitrate, organics and elemental composition to investigate possible sources, sinks, and conversion of ship emission derived compounds. Modeling of the chemical and physical processes on the basis of measured data is used to improve our understanding of the impact of ship emissions on the marine troposphere and coastal areas.
