    Assessment of the Sphericity of Submicrometer Particles Using a Single-particle Polar Nephelometer at an Urban Site in Japan by Maho Nakagawa, Tomoki Nakayama, Hiroshi Sasago, Yuki Kuruma, Hikari Yai, Shuhei Ogawa, Yange Deng, Michihiro Mochida, Yutaka Matsumi

    Published 2020-07-01
    “…Thus, to examine this property and its controlling factors, this study measured the scattering angular distributions of both thermodenuded and non-thermodenuded individual particles with a diameter of 500 nm in real time using a home-made polar nephelometer in Nagoya, Japan. Estimating the sphericities based on the depths of the local minima in the scattering angular distributions, we found the ambient aerosols to be external mixtures of at least two types of particles, one with relatively high and the other with relatively low sphericity. …”
