Effects of aerosol vertical distribution on the intensity and polarization properties of twilight

being only 14.64%, suggesting the potential utility of twilight polarization measurements in retrieving aerosol vertical distribution information. The simulated results generally show good consistency with the measurements taken by CE318-TP at Lingshan, Beijing. The results provide a theoretical basis for retrieving atmospheric aerosol properties at different altitudes based on twilight and also offer insights for the further improvement of twilight intensity and polarization simulations.
