![]() By late 2017, Román and colleagues hope to provide daily high-definition views of Earth at night. (Note that clouds and sunlight are added to some images on this page for aesthetic effect those data are drawn from our Blue Marble products.) The team has also reprocessed 2012 data with the new techniques so that researchers can compare and contrast light sources over the years. The compositing technique selected the best cloud-free nights in each month over each land mass. ![]() The images on this page show Earth’s night lights as observed in 2016 they are drawn from a new global composite map (below) that was just added to Worldview and GIBS. Freely available to the science community and public via the Web, GIBS and Worldview allow users to see natural- and false-color images of Earth within hours of satellite acquisition. A research team in the Earth Observing Satellite Data and Information System (EOSDIS) also has been working to integrate nighttime data into NASA’s Global Imagery Browse Services (GIBS) and Worldview mapping tools. ![]() Since the 2011 launch of the NASA-NOAA Suomi National Polar-orbiting Partnership (Suomi-NPP) satellite and the 2012 release of Earth at night maps, Román and colleagues at NASA’s Goddard Space Flight Center have been analyzing night lights data and developing new software and algorithms to make those data clearer, more accurate, and more readily available.
