Model analysis. We have changed the modeling analysis at the suggestion of the referees. The model study was performed to determine to what degree calculated CCN concentrations would be underor overestimated if the variability in the HOA mass fraction observed during GoMACCS was neglected. Modeled size distributions were constructed using a geometric mean diameter varying between 20 and 140 nm (the entire range of values observed during the experiment). For each size distribution, regardless of Dgn, the total number concentration was set to 3000 cm-3 as a normalizing factor and the geometric standard deviation was set to 1.5 representative of observed number-size distributions. Using critical diameters calculated from Köhler theory, CCN concentrations were determined for a matrix of insoluble mass fractions ranging from
