Summary
[edit]DescriptionCity Lights of South America’s Atlantic Coast (8250445190).jpg |
This image of part of the Atlantic coast of South America was acquired by the Suomi NPP satellite on the night of July 20, 2012. The image was made possible by the “day-night band” of the Visible Infrared Imaging Radiometer Suite (VIIRS), 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. “Nothing tells us more about the spread of humans across the Earth than city lights,” says Chris Elvidge, who leads the Earth Observation Group at NOAA’s National Geophysical Data Center. Named for satellite meteorology pioneer Verner Suomi, NPP flies over any given point on Earth's surface twice each day at roughly 1:30 a.m. and p.m. The polar-orbiting satellite flies 824 kilometers (512 miles) above the surface, sending its data once per orbit to a ground station in Svalbard, Norway, and continuously to local direct broadcast users distributed around the world. Suomi NPP is managed by NASA with operational support from NOAA and its Joint Polar Satellite System, which manages the satellite's ground system.

Suomi NPP is the result of a partnership between NASA, the National Oceanic and Atmospheric Administration, and the Department of Defense. Caption by Mike Carlowicz.
