As one approaches the poles, the angle of incidence decreases because the Sun's rays have to pass through a larger portion of the atmosphere at a more oblique angle. This causes the atmosphere attenuation to increase, as more of the Sun's energy is absorbed or scattered by the atmosphere before it reaches the ground.
