AB: A successive order of scattering vector radiative transfer code was used to simulate the high-resolution polarization spectra in the oxygen A-band. The effects of aerosol size distribution and vertical profile on the radiance and polarization at the top and bottom of the atmosphere were analyzed. Polarized radiances are dominated (>95%) by the first and second orders of scattering. The polarization due to higher orders of scattering can be simply parameterized. These insights provide a methodology for developing a fast forward model of vector radiative transfer and for retrieval algorithms to derive information of aerosol size distribution and vertical profile from high-resolution oxygen A-band measurements
