Fig. 1 The sampling area location on Spitsbergen, Svalbard. Collection sites for lake water (1), stream water (2) and atmospheric precipitation (3) are marked.
Fig. 2 Wind rose for the days with precipitation events in Hornsund.
Fig. 3 An output of HYSPLIT analysis of air mass back-trajectories (seven-day), expressed as frequencies of air trajectory crossing a given area and arriving to Hornsund on any of the precipitation sampling days, showing the predominance of the south-western quadrant of air mass sources.
Fig. 4 Air mass backward trajectory clusters (computed with HySPLIT) and their frequencies in the data set.
