A Changing Earth at Night
Satellite images of Earth at night—often referred to as “night lights”—have been a gee-whiz curiosity for the public and a tool for fundamental research for nearly 25 years. The map on the front of this poster shows the change in lighting intensity from 2012 to 2016. The map was created using two separate night lights datasets (from 2012 and 2016) derived using data from the Visible Infrared Imaging Radiometer Suite (VIIRS) on the National Oceanic and Atmospheric Administration (NOAA)-NASA Suomi National Polar-orbiting Partnership (NPP) satellite. The back of the poster explains how scientists use night lights data from VIIRS to study our planet at night.
