摘要
利用中国气象局寿县国家气候观象台的太阳光度计、浊度仪和颗粒物监测仪,观测并分析了寿县冬季大气光学特性,得到了气溶胶光学厚度、散射系数、吸收系数和单次散射反照率的日变化规律。结果表明,随着气溶胶含量的增加,颗粒物含量增加,气溶胶光学厚度、散射系数和单次散射反照率增大,气溶胶波长指数和大气浑浊度系数也增大。不对称因子、后向散射比、散射系数、单次散射反照率和波长指数表征了气溶胶粒子大小变化规律。
Abstract
By using the sun photometer, nephelometer and particle matter monitor of national climatology observatory in Shouxian, the atmospheric optical characteristics in Shouxian are observed and analyzed in winter. The daily variation rules of optical depth of aerosol, scattering and absorption coefficient, and single scattering albedo are obtained. Results show that, with the increasing of aerosol content, particle matter content also increases, the optical depth of aerosol, scattering coefficient and single scattering albedo increase, and the aerosol's wavelength index and atmospheric turbidity coefficient also increase. The size changing of aerosol particles can be characterized by asymmetric factors, backscattering ratio, scattering coefficient, single scattering albedo and wavelength index together.
