AçıklamaEffect of light pollution on sky polarization.jpg
English: These false color images compare the degree of linear polarization of the moonlit sky under different light pollution conditions. In the image at left the characteristic bands of polarization of Rayleigh scattered moonlight are clearly visible, while in the image at right light pollution from the city of Berlin washes out the signal.
The photos are centered on the North Star. The technique used to determine the polarization requires multiple photographs, leading to false polarization signals from the the movement of bright stars. For this reason, the brightest star trails were removed.
These images are based on data published in the Journal of Geophysical Research[1].
The sets of polarized photographs used to generate the images were taken about 90 minutes apart, on the night of February 21-22. The urban location is in Dahlem, Berlin (52.4577°N, 13.3107°E), and the rural location is an unlit parking lot adjacent to a wildlife sanctuary (52.5296°N, 12.9978°E), approximately 28 km East of Berlin's center.
