It was first published in a 2001 Sky & Telescope article. The reality behind the use of the scale is the enormous amount of artificial light pushed into the sky by human …Within the yellow areas, there are various pockets of light pink, which are the most light-polluted areas. Most of these light pink pockets in the U.S. are cities, which are typically more population-dense (and building-dense than surrounding areas). These include: New York City, Philadelphia, Boston, Rochester, Pittsburgh, Chicago, Atlanta ...The light pollution map has two base layers (road and hybrid Bing maps), VIIRS/World Atlas/Clouds/Aurora overlays and a point feature overlay (SQM, SQC and Observatories). If you want detailed analysis of radiance (VIIRS/DMSP) changes over a period of time, then please use the Lighttrends web application (not mobile optimised).
A map showing the domain of the 6 continent-scale maps is below. There are two versions of each map: one with borders and coastlines and the other with nothing except light pollution. The resolution of most maps is 1/120 degrees. The medium resolution world maps are 1/40 degrees. I've used an "expanded color scale" for all maps.
Low light pollution conditions, or dark skies, is one of the most important properties of a good astronmical observing site. This map is a small exerpt (381mi east-to-west, by 346mi north-to-south) from the by David Lorenz. David recalculated the with newer data. The central cross marks the location of the Big Bear City clear sky chart.
