内容 研究概要:Atmospheric fine particles, aerosols less than 2μm in diameter, were collected on filters and chemically analyzed in Sapporo, Okinawa island in Japan and Ester-Dome, Alaska in U. S. A. They were made up of nine components such as elemental carbon, organics, sulfate, nitrate, ammonium, sea-salt cations, soil and water. Based on the chemical characterization, it was assumed that atmospheric aerosols comprise seven species of particles such as elemental carbon, organics, ammonium sulfate, ammonium nitrate, sea-salt, soil particles and mixed nuclei which have inner core of elemental carbon and outer shell of sulfate. Using log-normal size distribution, complex index of refraction and atmospheric concentrations of each chemical species particles, single scattering albedo and volume extinction coefficient of aerosols were evaluated by calculation with Mie scattering theory.
