![]() Using technology provided by Google, Proville and his co-authors were able to go deeper - crunching the numbers on 21 years of data at a granular level and examining the correlations between light and eight major variables, including population, emissions and poverty. See in the Turn Off the Lights Options page -> Night Mode tab -> and here you. Based on this trove of satellite data, Proville and fellow researchers were able to demonstrate that a nation’s nocturnal glow is a powerful predictor of a wide variety of demographic, economic and industrial indicators.ĭue to the staggering gigabytes of data that are publicly available from government satellites, most previous efforts to correlate nighttime lights with variables like a region’s economy have been limited to a few years of data or a handful of countries. So you can activate it with a long press on the current web page. Trying to add further realism to the conditions of the Earth, I like to see where the night and day side of the Earth is at the moment. Countries might report economic or industrial progress in different ways, using different methods of measurement or even cooking the books for better headlines, but the amount of light they emit is gauged the same way from every spot on Earth. The Night Earth map shows the lights that are visible at night on the Earths surface. It produces colorful, high quality, high resolution. The high-speed economic development inevitably led to rapid changes in land cover types, e.g., an increment in artificial features (built-up) and decrement in natural features (vegetation). EarthView is a dynamic desktop wallpaper and screen saver, which displays beautiful views of the earth with daylight and night shadows. While it makes for a pretty picture, data on how much light a place emits at night is also valuable when it comes to geopolitics, thanks to the unadulterated democracy of studying light from space. Monthly average radiance composite images using nighttime data from the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB). Hefei’s gross domestic product (GDP) growth rate ranks first among all cities in China, and it was the fastest-growing city in China from 2000 to 2020.
