In order to study the characteristics of cloud, a real-scale experiment for cloud generation was carried out using an extinct vertical mine (430 m height) located in the northeastern Honshu, Japan. The dry particles generated from the three-step concentrations of NaCl solutions were used for cloud generation. The number size distributions of initial dry particles and cloud droplets were monitored by Scanning Mobility Particle Sizer (SMPS) and Forward Scattering Spectrometer Probe (FSSP) at bottom and upper sites of pit, respectively. The polymeric water absorbent film (PWAF) method was employed to measure liquid water content (W<SUB>L</SUB>) as a function of droplet size. Moreover the chemical properties of individual droplet replicas were determined by micro-PIXE. The CCN number concentration shows the lognormal form in dependence of the particle size, while the number size distributions of droplets are bimodal showing the peaks around 9 ㎛ and 20 ㎛ for every case. In comparison to background mineral particles, right shifting of size distribution line for NaCl particles was occurred. When NaCl solutions with three-step different concentrations were nebulized, W<SUB>L</SUB> shows the strong droplet size dependence. It varied from 10.0 ㎎ m?³ up to 13.6 ㎎ m?³ with average 11.6 ㎎ m?³. A good relationship between WL and cloud droplet number concentration was obtained. Both chemical inhomogeneities (mixed components with mineral and Cl) and homogeneities (only mineral components or Cl) in individual droplet replicas were obviously observed from micro-PIXE elemental images.
