When the Sun is located near one of the horizons, its light passes through a larger amount of atmosphere before reaching the observer. This causes the scattered light to be preferentially polarized in a plane that is perpendicular to the direction of the Sun. As a result, an observer looking at the sky directly overhead will view partially polarized light, which is due to scattering of sunlight by the atmosphere, and not due to reflection, double refraction, or selective absorption.
