Description

technical field [0001] The invention belongs to the field of atmospheric measurement, in particular to the field of optical characteristic measurement of atmospheric aerosol, and in particular relates to a single-scattering albedo profile measurement system of an unmanned aerial aerosol. Background technique [0002] Atmospheric aerosols refer to liquid or solid particles suspended in the atmosphere, which are variable in time and space and complex in chemical composition. Atmospheric aerosol single-scattering albedo (ω) refers to the ratio of the aerosol scattering coefficient to the extinction coefficient (the extinction coefficient is the sum of the absorption coefficient and the scattering coefficient). Quantities used to calculate direct radiative forcing by aerosols. The vertical profile of atmospheric aerosol single scattering albedo refers to the profile curve of aerosol single scattering albedo with height, which is of great significance for aerosol-climate researc...
