The results demonstrate that the shape distribution indeed exerts a significant influence on the skylight degree of linear polarization. The skylight polarization calculated assuming the microscope-measured shape distributions is distinct from that using the inversion-based shape distributions. The significant effects will influence the retrieval of the sphericity of aerosols based on the sun-sky radiometer measurements. Our results suggest that using representative shape distributions obtained by direct microscopic observations of aerosol samples captured in the natural atmosphere has a high potential to improve the retrieval of the aerosol shape parameter.Lire moins >
