Nighttime image of Europe, Africa, and Asia using the Day/Night Band (Enhanced Near Constant Contrast) acquired on 29 December 2019 by the Visible Infrared Imaging Radiometer Suite (VIIRS) Instrument, aboard the joint NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) satellite.
The VIIRS Nighttime Imagery (Day/Night Band, Enhanced Near Constant Contrast) layer shows the Earth’s surface and atmosphere using a sensor designed to capture low-light emission sources, under varying illumination conditions. It is displayed as a grey-scale image. The layer is useful for showing patterns of human activity and energy behaviors such as cities and highways, the tracking of shipping and fishing fleets at night and the burning of waste natural gas (gas flares) from on and off shore oil/gas production sites.
