Sources of Light Waste & Pollution - 5/6

Natural Weather-Related Causes of Light Pollution

  Fog

  Snow

  Rain

  Clouds

  Smog

  Dust

Light from exterior fixtures is sent outward and upward into the surrounding area and the night sky by particles in the air. Refraction and reflection from the above conditions then cause light pollution and sky glow. Snow and ice is extremely reflective. Controlling waste light is thus highly recommended in order to reduce light pollution caused through natural, weather-related factors.

  Smoke

Falling and settled snow are highly reflective of any light and add greatly to the light pollution problem in urban communities. The reflected light will occur from any type of light, even high-efficiency lights. Effective light control with computer/sensor-controlled lights will greatly reduce waste light and light pollution not to mention energy and related costs.
