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 #39;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 #39;s Earth Observatory with data processed by NOAA #39;s National Geophysical Data Center and combined with a version of the Earth Observatory #39;s Blue Marble: Next Generation. earthobservatory.nasa.gov This video is public domain and can be downloaded at: svs.gsfc.nasa.gov Like our videos?
