(2013a) introduced the method of the bead-mobility technique to determine viscosity of aerosol particles. In this study, bead speeds were measured at different relative humidity (RH) and then the bead speeds were converted to viscosities using a calibration line (Fig. S1). The calibration line was produced by

The values were fit to a power function, bead speeds (μm/ms) = ɑ × (viscosity (Pa s), η) b . 15 a, b are the best-fit parameters, and used ɑ = 1.84×10 -4 and b = -1.08 in this study. The values agree well with the previous study of Renbaum-Wolff et al. (2013a).
