The numerical results of the retrieved radius in the lower panel of Fig. 6 in [1] were incorrect because of an error in the retrieval algorithm which calculated the radius by automatic tracking the resonances using the cross correlation technique (see [1] for details). The error affects the numerical value given in the figure caption for the evaporation rate in the solid state, and the vapor pressure value of solid succinic acid in the text.

The corrected lower panel of Fig. 6 is displayed below. The corrected value of the vapor pressure of solid succinic acid at 298.5 K is now p = (6.4 ± 2.2) × 10⁻⁶ Pa.

This does not change the interpretation of the results nor any of the conclusions drawn in [1].

 

Fig. 1. Evaporation behavior of a SA particle at T=298.5 K, RH slightly decreasing at RH ≈ 50%, efflorescing at t = 20,197 s (the phase transition is determined from 2-dimensional angular scattering data, not shown here). Upper panel: temporal evolution of resonance spectra (color coded intensity). The deduced radius squared is plotted in the lower panel (black curve). Linear fits to datapoints for liquid and solid states yield dr ²/dt = 2.99 × 10⁻⁴ μm ²/s and dr ²/dt = 3.16 × 10⁻⁶ μm ²/s (dashed blue and orange lines, respectively).
