dc.description.abstract | Svalbard is a remote and scarcely populated Arctic archipelago and is considered to be mostly influenced by long-range-transported air pollution. However, there are also local emission sources such as coal
and diesel power plants, snowmobiles and ships, but their influence on the background concentrations of trace
gases has not been thoroughly assessed. This study is based on data of tropospheric ozone (O<sub>3</sub>) and nitrogen
oxides (NO<sub>x</sub> ) collected in three main Svalbard settlements in spring 2017. In addition to these ground-based
observations and radiosonde and O<sub>3</sub> sonde soundings, ERA5 reanalysis and BrO satellite data have been applied
in order to distinguish the impact of local and synoptic-scale conditions on the NO<sub>x</sub> and O<sub>3</sub> chemistry. The measurement campaign was divided into several sub-periods based on the prevailing large-scale weather regimes.
The local wind direction at the stations depended on the large-scale conditions but was modified due to complex
topography. The NO<sub>x</sub> concentration showed weak correlation for the different stations and depended strongly on
the wind direction and atmospheric stability. Conversely, the O<sub>3</sub> concentration was highly correlated among the
different measurement sites and was controlled by the long-range atmospheric transport to Svalbard. Lagrangian
backward trajectories have been used to examine the origin and path of the air masses during the campaign. | en_US |
