| Zusammenfassung |
| NOx (NO and NO2) play a key role in tropospheric chemistry and affect human health and
the environment. Shipping emissions contribute substantially to the global emissions of
anthropogenic NOx. Due to globalization and increased trade volume, the relative importance
emissions from ships gain even more importance.
The Airborne imaging DOAS instrument for Measurements of Atmospheric Pollution
(AirMAP), developed at IUP Bremen, has been used to perform measurements
of NO2 in the visible spectral range. The observations allow the determination
of spatial distributions of column densities of NO2 below the aircraft. Airborne
measurements were performed over Northern Germany and adjacent coastal waters
during the NOSE (NO2 from Shipping Emissions) campaign in August 2013. The
focus of the campaign activities was on shipping emissions, but NO2 over cities and
power plants has been measured as well. The measurements have a spatial resolution
below the order of 100 x 30 m2, and they reveal the large spatial variability of NO2
and the evolution of NO2 plumes behind point sources. Shipping lanes as well as
plumes of individual ships are detected by the AirMAP instrument. In this study, first
results from the NOSE campaign are presented for selected measurement areas. |
