Extended Data Fig. 2: GR4.5-10 by different methods.

Bars corresponding to ‘Calc H2SO4 + MSA + HIO3’ and ‘Calc H2SO4’ represent the theoretical growth rate as calculated by ref. 46 due to several vapours, and H2SO4 respectively, the rightmost bars show growth rates calculated by the lognormal fitting method applied to NanoSMPS data. Errors on growth rates fitted to SMPS data are ±50%, errors on calculated growth rates are +100%/-50%.
