“…Sulfuric acid (H 2 SO 4 ) is typically understood to be the most prevalent nucleation-inducing agent in NPF events, together with other airborne chemical species, including nitric acid (HNO 3 ), bases (e.g., amines), and organic acids (Zhang et al, 2012(Zhang et al, , 2015Kulmala et al, 2013;Wagner et al, 2017;Lehtipalo et al, 2018;Kürten, 2019;Lee et al, 2019;Brean et al, 2021;Olin et al, 2022). Numerous studies have also reported low-volatility organic species, such as terpene oxidation products and organic nitrates, participating in the formation of new particles (Berkemeier et al, 2016;Tröstl et al, 2016;Barsanti et al, 2017;Dall'Osto et al, 2018;Kerminen et al, 2018;Lee et al, 2019;Heinritzi et al, 2020).…”
