“…Consistent with this seasonal difference in particle number concentrations, most summertime non-sea salt sulfate mass concentrations were at least 5 times higher than winter concentrations (Jourdain and Legrand, 2002;Weller and Wagenbach, 2007;Udisti et al, 2012;Legrand et al, 2017a;Asmi et al, 2018), likely because of the contributions from biogenic DMS emissions from the surrounding Southern Ocean. However, most sea salt aerosols had wintertime maximum concentrations with more than 2 times more Na + mass concentrations in winter than summer (Parungo et al, 1981;Wagenbach et al, 1998;Jourdain and Legrand, 2002;Weller and Wagenbach, 2007;Jourdain et al, 2008;Udisti et al, 2012;Legrand et al, 2017a, b;Asmi et al, 2018).…”
