Within a 6 week measurement campaign in July and August 2016, ship emissions were measured at the river Elbe in Hamburg, Germany using the Long Path(LP)-DOAS technique. The measurements were carried out within the framework of the project MESMART (Measurements of shipping emissions in the marine troposphere) which investigates the influence of ship emissions on chemical processes in the atmosphere and monitors the correct use of low sulphur ship fuel.

A LP-DOAS instrument was set up side by side to a MESMART in situ measurement station at the river Elbe at Wedel (15 km downriver of Hamburg harbour). Emission signatures of NO₂ and SO₂ of about 4000 passing ships were monitored and combined with AIS data. The study shows that the LP-DOAS measurements are well suited to monitor ship emissions and the correct use of low sulfur ship diesel. An overview of observed emission factors for different ship types will be presented.
