Outline of Final Research Achievements

Polarization optical particle counter (POPC) measurement and a filter sampling of atmospheric aerosol particles was conducted in Kofu to develop an method distinguishing aerosol type, which are mineral dust and air pollution particles. Comparison between chemical composition of an aerosol particle and the POPC measurement determines the method using the particle diameter and the depolarization ratio of the scattering light. The POPC measured free-tropospheric aerosol particle at the top of Mt Fuji on July-August 2013, and Senjojiki, Kisokomagatake, where the altitude is 2640m, since December, 2013. The results sometimes show air pollution aerosol particle concentration higher than that in Japanese city areas and Asian dust. It indicates that the aerosol particles were come from the continent with back-trajectory analysis.
