We present a method to model the polarized Galactic synchrotron emission in the microwave range (20-90 GHz), where this radiation is expected to play the leading role in contaminating the cosmic microwave background (CMB) data. Our method is based on real surveys and aims at providing the real spatial distributions of both polarized intensity and polarization angles. Its main features are the modelling of a polarization horizon to determine the polarized intensity and the use of stalight optical data to model the polarization angle pattern. Our template is virtually free from Faraday roation effects as required at frequencies in the cosmological window.

Abstract
We present a method to model the polarized Galactic synchrotron emission in the microwave range (20-90 GHz), where this radiation is expected to play the leading role in contaminating the cosmic microwave background (CMB) data. Our method is based on real surveys and aims at providing the real spatial distributions of both polarized intensity and polarization angles. Its main features are the modelling of a polarization horizon to determine the polarized intensity and the use of stalight optical data to model the polarization angle pattern. Our template is virtually free from Faraday roation effects as required at frequencies in the cosmological window.
