Polar nephelometers for light scattering by ice crystals and aerosols: design and measurements

摘要: The angular distribution of light scattered from a particle is dependent on its size, shape, composition and the wavelength polarization state incident light. This information tremendous interest to many researchers due implications in fields remote sensing, climatic effects radiative transfer, industrial scientific laboratories applications such as aerosol monitoring (Hansen Lacis 1990; Liou et al. 1999; Mishchenko 1995). measured scattering patterns can lend insights into chemical physical properties particles (i.e., Pluchino 1987; Swanson Shaw 1979). these data shown by over 25 polar nephelometers (PN) described this chapter, that have been built since 1960s experimentally examine various small particles. goals measurements are either verify increasingly complex theoretical methods calculating non-spherical particles, or use intensities infer optical,
