Abstract

In order to study the optical properties of marine aerosols, the optical thickness, wavelength index, spectral distribution, refractive index, single scattering albedo and elevation of aerosol particles were measured by means of solar radiometer, micro pulse lidar and automatic weather station in Qingdao, South China Sea, East China Sea and South China Sea from July to November 2019. The results show that the aerosol optical thickness measured by the shipborne data is smaller than that measured by Qingdao and islands, and the aerosol elevation range is about 0.4-0.7, The diurnal variation is relatively stable, and the distribution of aerosol colloidal product spectrum in the offshore and the open sea has the same change trend. The radius of the coarse mode is about 2.4 μm-3.6 μ M. compared with other data, the real part of the refractive index is larger, the imaginary part is smaller, and the difference in the long wave band is more obvious. The single scattering albedo basically does not change with the wavelength.
