NASA Earth at Night

In daylight our big blue marble is all land, oceans and clouds. But the night - is electric. • This view of Earth at night is a cloud-free view from space as acquired by the Suomi National Polar-orbiting Partnership Satellite (Suomi NPP). A joint program by NASA and NOAA, Suomi NPP captured this nighttime image by 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 observe signals such as city lights, gas flares, and wildfires. This new image is a composite 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 land surface. • This video uses the Earth at night view created by NASA's Earth Observatory with data processed by NOAA's National Geophysical Data Center and combined with a version of the Earth Observatory's Blue Marble: Next Generation. • http://earthobservatory.nasa.gov/Nigh... • This video is public domain and can be downloaded at: http://svs.gsfc.nasa.gov/goto?11157 • Like our videos?
