Earth at Night
This
new global view of Earth's city lights is a composite assembled from
data acquired by the Suomi National Polar-orbiting Partnership (NPP)
satellite. The data was acquired over nine days in April 2012 and 13
days in October 2012. It took 312 orbits to get a clear shot of every
parcel of Earth's land surface and islands. This new data was then
mapped over existing Blue Marble imagery of Earth to provide a realistic
view of the planet.

The image was made possible by the
satellite's "day-night band" of the Visible Infrared Imaging Radiometer
Suite, which detects light in a range of wavelengths from green to
near-infrared and uses filtering techniques to observe dim signals such
as city lights, gas flares, auroras, wildfires and reflected moonlight.


The day-night band observed Hurricane Sandy, illuminated by moonlight,
making landfall over New Jersey on the evening of Oct. 29. Night images
showed the widespread power outages that left millions in darkness in
the wake of the storm.
