This image may not be used to state or imply NOAA endorsement of any company or product World at night, showing the change in illumination from 1993-2003. This data is based on satellite observations. Lights are colour-coded. Red lights appeared during that period. Orange and yellow areas are regions of high and low intensity lighting respectively that increased in brightness over the ten years. Grey areas are unchanged. Pale blue and dark blue areas are of low and high intensity lighting that decreased in brightness. Very dark blue areas were present in 1993 and had disappeared by 2003. The abundance of red and yellow on the map shows that nights are getting brighter in many areas, especially in the developing world.
