Abstract: According to the technical solution of the present invention, a vertical mass concentration curve of fine aerosol component distribution can be obtained based on remote sensing test cooperation of a ground Lidar and a solar photometer, specifically, an internal mixing model and a normalized volume distribution model are constructed according to the light absorptivity and the water solubility of aerosol components, and separates out profiles of inorganic salt components, black carbon components, water-soluble organic matter, water-insoluble organic matter, fine aerosol water content components and the like to obtain corresponding vertical distribution. A new thought and development direction can be provided for remote sensing inversion of Lidar and the like, and meanwhile, development of aerosol component spectrums is promoted.

Abstract: A method for inverting aerosol components using a LiDAR ratio and a depolarization ratio, includes: S1. identifying sand dust, a spherical aerosol and a mixture of the sand dust and the spherical aerosol based on a depolarization ratio; S2. calculating a proportion of the sand dust in the mixture of the sand dust and the spherical aerosol; and S3. identifying soot and a water-soluble aerosol in the spherical aerosol based on a LiDAR ratio. In the present disclosure, only a wavelength with a polarization channel is needed, to identify the aerosol components, achieving high accuracy with low detection costs.
