![]() This practice produces a large flare of burning gas that illuminates the surrounding area and vents heat and pollution into the atmosphere. The flared natural gas was originally dissolved in the crude oil and came out of solution at the time of production.ĭrilling companies burn it by flaring because the gas is inconvenient or unprofitable to use on the drilling site, or, because it is too costly to transport to market. The map also shows the geographic extent of active oil fields revealed by their electric lights, and, the light and heat produced by natural gas flaring. The most obvious pattern on the map is the geographic distribution of cities revealed by their electric lights. NASA used this data to produce a map that displays night-time electric illumination and heat sources across the planet. ![]() ![]() In April 2012 and October 2012 the satellite collected cloud-free night observations of visible and infrared light. This data allows NASA to map the glow of natural events and human activity across the planet. The VIIRS observes visible and infrared wavelengths of light emanating from Earth. These instruments include the VIIRS (visible infrared imaging radiometer suite). It orbits the Earth about 14 times each day, observing the surface and collecting data using a variety of instruments. NASA launched the Suomi NPP spacecraft in October 2011.
