Air Quality in Ny-Ålesund. Monitoring of Local Air Quality 2019 and 2020.

The concentrations of the measured components are generally low and below national limit values for the protection of
human health and critical levels for the protection of vegetation. Wind from northern sectors gave the highest average concentrations of nitrogen oxides and sulfur dioxide, which indicates the power station and the harbour as possible sources. We also see single episodes of long-range transport of sulfur dioxide.
