Waterfalls as sources of small charged aerosol particles

[摘要] In this study, we measured the mobility distributions of clusterand intermediate ions with an ion spectrometer near a waterfall.We observed that the concentration of negative 1.5–10 nm ions wasone-hundred fold higher than a reference point 100 m away from thewaterfall. Also, the concentration of positive intermediate ionswas found to be higher than that at the reference point by afactor of ten. This difference was observed only at the smallestsizes; above 10 nm the difference was insignificant.
