    "abstract": "Polarimetric observations of the twilight sky are effective for the\ninvestigations of scattering properties of the atmosphere at different\naltitudes. Modern computer technique allows to reduce the influence of multiple\nscattering on the twilight sky background which is necessary for the aerosol\ninvestigations. In this paper the results of polarimetric observations of the\ntwilight sky are discussed and compared with the numerical analysis by MCC++\nmodel for different models of atmospheric aerosol. As it was found, the model\nof urban troposheric and background stratospheric aerosol shows the best\nagreement with observed polarimetric properties of the twilight sky.",
