Polarization Patterns of Cloudy Skies and Animal Orientation
Chapter
Abstract
The polarization of light originating from an area of the sky covered by clouds (termed “cloudlight”) consists of two components:
- 1.
The first originates from the cloud itself. White light illuminating the cloud remains white, but becomes partially linearly polarized after scattering on the cloud particles (ice crystals or water droplets).
- 2.
The second component is caused by the scattering of light within the air column between the cloud and the observer. This column scatters bluish and partially linearly polarized light.
