From: Oceanic evasion fuels Arctic summertime rebound of atmospheric mercury and drives transport to Arctic terrestrial ecosystems

Fig. 5

a–c Spatial distribution of the average atmospheric dry deposition flux of Hg0 (µg/m2/month) across Arctic coastal continents in June, July, and August, respectively. d–f Backward air mass trajectories arriving at the Toolik Field Station (68.6° N, 149.6° W) for the corresponding months, calculated using 6-hourly Global Data Assimilation System (GDAS) meteorological data from 2015 to 2016. Trajectory clusters are identified using cluster analysis, with the percentages shown representing the relative contribution of each air mass cluster to the total number of trajectories. Panel d, e were generated using Meteoinfo software (http://www.meteothink.org/)69.
