Summary[edit]

Description
English: NASA image acquired April 18 - October 23, 2012

This image of the United States of America at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012. The image was made possible by the new satellite’s “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.

Instrument: Suomi NPP - VIIRS

Projection: Albers equal-area conic, WGS84 datum, standard parallels 29.5°N and 44.5°N, central meridian 96°W, origin latitude 23°N

On this image one pixel is (737.19 × 737.19)m²
