Short summary
This paper first presents an estimate of the real part of the refractive indices and effective densities of chemically segregated aerosols in China. The results indicate the presence of spherical or nearly spherical shape for the majority of particle types. While sharing refractive index in a narrow range (1.47–1.53), they exhibited a wide range of effective density (0.87–1.51). Detailed relationship between physical and chemical properties benefits future research on visibility and climate.
