Light Pollution Atlas 2022
Welcome to the latest version of the World Atlas of the Artificial Night Sky Brightness! I've re-calculated Pierantonio Cinzano's original atlas using more recent satellite data from 2022. There are also earlier versions from 2006, 2016 and 2020.

The maps have a new expanded color scale.
The Maps:
The full resolution world map is very hard to view due to its size. Therefore I also have a medium resolution world map and full resolution continent-scale maps that may be easier to use. 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.
