Abstract:

A sensitive large-ion counter was developed for determination of mobility distributions in natural aerosols at low particle concentrations in clean atmospheres. Results obtained at mountain stations and on sea are shown. A gravimetric method is described for determination of the growth of aerosol samples in vapors of water and of organic solvents. Experiments with natural and artificial aerosols have been performed to study the form and the hysteresis effect of the growth curve of natural continental aerosols. A solution method was developed for determination of the organic components in natural aerosols.
