The images above were acquired on July 25, 2013, and December 26, 2013, by the Visible Infrared Imaging Radiometer Suite on the Suomi NPP satellite. The images show subtle differences in the amount of nighttime light around urban areas in California, Nevada, Arizona, and northwest Mexico between mid-summer and the December holidays. Turn on the image comparison tool to spot the differences.

Examining daily data from Suomi NPP, scientists have identified how patterns in nighttime light intensity change during major holiday seasons. According to the data, nighttime lights around many U.S. cities shine 20 to 50 percent brighter during Christmas and New Year’s when compared to light output during the rest of the year.
