12 November 2020Seasonal and interannual variations of aerosol and black carbon concentrations in near-surface atmospheric layer over Barentsburg (Spitsbergen, 2011-2019)
We discuss the specific features of seasonal and interannual variations of aerosol and black carbon concentrations in the near-surface atmospheric layer at polar station Barentsburg (Spitsbergen) during 2011-2019. Over the observation period, the diurnally average values had been 7.1 ± 6.65 cm–3 for aerosol concentration and 120 ± 131 ng/m3 for black carbon concentration. In the seasonal behavior of aerosol concentration there are a maximum in March-April and a low level of values from June to November; the black carbon concentration shows maxima in August and April. The increased black carbon concentrations (in July-October), as compared to other polar stations, are caused by the effect of local anthropogenic sources.
