    • note
    • The nucleation rate is more precisely defined as the rate at which particles of critical size are produced. In this study, we detect only particles larger than 3 nm, and hence the value estimated from the rate of observed particle formation may be smaller than that of cluster formation.

    • For benzoic and p-toluic acids and the experimental conditions similar to those in Fig. 2, the measured particle concentrations were slightly higher (by about 10 to 20%) when the water flow in the aerosol chamber was turned off.
