| Research Abstract |
Volume fraction(ε) of water soluble material in atmospheric aerosol particles is an important parameter relating to activation processes to cloud droplets and ice particles. In order to estimateεof individual coarse dust particle, a confocal scanning laser microscope was applied to direct measurement of volume difference of individual particles before and after water-dialysis. Individual particles of reference test dust samples and coarse particles during Asian dust events were analyzed forε. To measure ice forming capability using a Continuous-Flow Diffusion Chamber, assessment of the performance based on a computational fluid dynamics analysis, modification of the instrument, and a test experiment for atmospheric aerosol were performed.
