By solving the vector radiation transmission equation with the successive order of scattering method, the polarization characteristics of the light scattered by the atmosphere aerosols under different earth surface reflection models are studied. Two surface reflection models, single surface reflection and coupled surface reflection, are used in the numerical simulations. The reflectivity of earth surface is obtained according the corresponding model. The Stokes vector of the scattered light is derived by solving the vector radiation transmission equation with successive order of scattering method. Furthermore, the polarization degree of the scattered light is calculated. The simulation results show that the scattering radiation intensities of the first scattering order are equal for the two earth surface models. It is the same case for polarization degree of the first scattering order light. On the other hand, the total scattering radiation intensity of the coupled surface reflection model is larger than that of the single surface reflection model; The contribution of the first scattering light of the coupled model is smaller than that of the single reflection model. The results are of significance to the inversion of aerosol optical properties.
