In this letter we simulated the top of atmosphere (TOA) polarization patterns with scattering and absorbing aerosol situations through a successive orders of scattering (SOS) radiative transfer model. In the analysis of single scattering properties of aerosol particles, absorbing aerosol has an obvious different pattern from those non-absorbing aerosols. The TOA Degree of Linear Polarization (DoLP) decreases significantly when scattering aerosol optic depth (AOD) increases. While for absorbing aerosol case, the TOA DoLP keep stable or even increases when aerosol absorbing AOD increases, which suggest a way to retrieve absorbing property of aerosol.
