Data from DMSP’s Operational Linescan System can be used to see city lights. The DMSP satellites are run by the National Oceanic and Atmospheric Administration, monitoring the meteorological, oceanographic and solar–terrestrial physics environments for the US Department of Defense. This year, ESA astronaut and WWF ambassador André Kuipers will photograph Earth from the International Space Station as people pull the plug on all non-essential lights from 20:30 to 21:30 local time.įor more information, visit the Earth Hour website. This sixth annual 'Earth Hour' is organised by the World Wildlife Fund and supported by ESA. On 31 March, millions of people around the world will switch off their lights for 60 minutes in a demonstration against climate change and to promote a more sustainable lifestyle. This is evident in all areas pictured in the animation.īut by indicating population and economic growth, bright spots on these images also represent areas of high energy consumption, emissions and pollution – factors that greatly contribute to climate change. The images paint an expansive and revealing picture, showing how humans have illuminated and shaped the planet in profound ways since the invention of the light bulb 140 years ago. you can generate fully rendered, rotatable, zoomable views of earth as seen from space. For nearly 25 years, satellite images of Earth at night have served as a fundamental research tool, while also stoking public curiosity. Over that 18-year period, the country’s gross domestic product jumped some $377 billion. Idealized satellite view of earth with day / night bouandary. For example, lights in Poland in 1992 appear dim, but are multiplied in the 2010 image. Increased illumination in the second image is also an indicator of economic growth. The images show night illumination for 19.īright areas highly correlate with high population density – such as the densely populated cities like London, Paris and Rome.Ĭoastal areas are also more populated than inland regions, making the outline of Europe clearly visible in these night images.
