Earth at night _NASA 🌏

This nighttime view of Earth is a cloud-free view from space as captured by the Suomi National Polar Orbiting Partnership Satellite (Suomi NPP). Suomi NPP, a joint program of NASA and NOAA, obtained this nighttime image using the satellite's Visible Infrared Imaging Radiometer Suite (VIIRS). The day-night band on VIIRS detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to look for signals such as city lights, gas flares and forest fires. The new image is a combination of data acquired over nine days in April and thirteen days in October 2012. It took 312 satellite orbits and 2.5 terabytes of data to get a clear shot of every parcel of Earth's surface.

This video uses night vision produced by NASA's Earth Observatory, processed by NOAA's National Geophysical Data Center and combined with Earth Observatory's version of Blue Marble: Next Generation.
