This image shows human-generated nighttime lights in Europe for the calendar year 2003, based on observations by the Defense Meteorological Satellite Program Operational Line Scanner. In this image, oceans appear black, landmasses appear in varying shades of blue, and lights appear yellow-white. Because these images focus on human impact, they do not include other (natural) light sources. Besides assembling cloud-free images, data visualizers carefully excluded sunlight, moonlight, and light from the Northern Hemisphere aurora.
