      abstract     = {The influence of shipping on air quality over the Southern
                      Baltic Sea was investigated by characterizing the horizontal
                      and vertical distribution of aerosols and trace gases using
                      airborne measurements in the summer of 2015. Generally,
                      continental and anthropogenic emissions affected the
                      vertical distribution of atmospheric pollutants, leading to
                      pronounced stratification in and above the marine boundary
                      layer and controlling the aerosol extinction. Marine traffic
                      along the shipping corridor “Kadet Fairway” in the
                      Arkona Basin is shown to influence the presence and
                      properties of both trace gases and aerosol particles in the
                      lowest atmospheric layer. Total particle number
                      concentration and NOy mixing ratio increased in the corridor
                      plumes, relative to background, by a factor 1.55 and 3.45,
                      respectively. Titration, triggered by the enhanced presence
                      of nitrogen compounds, led to a median ozone depletion of
                      $19\%$ in the corridor plumes. The enforcement of the
                      Sulphur Emission Control Area (SECA) might be responsible
                      for the minor sulphur dioxide increase $(20\%)$ in the
                      corridor plumes. Ship traffic caused a minor enhancement of
                      black carbon mass concentration, estimated to be around
                      $10\%.$ The study of individual ship plumes indicated that
                      ship emitted aerosol was substantially different from
                      background aerosol: fresh ship exhaust was preferentially
                      enriched in aerosol particles with diameters below 100 nm
                      and in black carbon particles with core diameters above
                      300-400 nm. With the present work the impact of marine
                      traffic on the concentration and properties of atmospheric
                      components within the marine boundary layer over the open
                      water of the Southern Baltic Sea is assessed with airborne
                      observations for the first time. Due to the high uncertainty
                      affecting the estimations of ship emissions, this dataset
                      represents a valuable reference for the assessment of ship
                      emission inventories and related environmental-climatic
                      impacts on the Southern Baltic Sea},
