SOA compositions and size distributions for the experiment MT-18012013 measured with an HR-TOF-AMS instrument at high RH before any cloud event (a), during the first cloud event (b), and after the first cloud event (c). (left) Normalized mass spectra of the organic components of dried aerosol. (right) Dried aerosol size distributions. Cx stands for C-containing fragments, CH stands for CH fragments, CHO1 stands for CHO fragments with only one oxygen atom, CHOgt1 stands for CHO fragments with more than one oxygen atom, CHN stands for CHN fragments, CHO1N stands for CHON fragments with only one oxygen atom, CHOgt1N stands for CHON fragments with more than one oxygen atom, HO stands for OH⁺, H₂O⁺, H₃O⁺ fragments and their isotopes.
