DMSP Global Composites

National Geophysical Data Center

Using overlays from the Defense Meteorological Satellite Program, researchers at the National Geophysical Data Center in the United States have created a Google Earth file showing how the planet looks at night. From 1992 to 2003, these overlays allow you to see the increase in light pollution as population expands and the accessibility to electricity increases. For example, zoom into Dubai and check out the differences between 1992 and 2003.
