NASA has released a new composite map of nighttime satellite images of the Earth. The map is made up of the best cloud-free satellite images of each land mass captured during 2016. You can view the new 2016 Black Marble map on NASA's Worldview interactive map.
A number of factors can affect how light appears in nighttime satellite imagery. The phases of the moon, atmospheric conditions and clouds can all change the way that light on the Earth appears when viewed from space. To create the Black Marble map NASA filters out these factors to provide a more consistent global map of the world at night.
As well as exploring the new 2016 Night Light map on Worldview you can also view and download 2016 night light images and learn more about night light science on NASA's Earth at Night page.
