City lights shine brighter during the holidays when compared with the rest of the year, as shown using a new analysis of daily data from the NASA-NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) satellite. Dark green pixels are areas where lights are 50 percent brighter, or more, during December.
This new analysis of holiday lights uses an advanced algorithm, developed at NASA's Goddard Space Flight Center in Greenbelt, Maryland, that filters out moonlight, clouds and airborne particles in order to isolate city lights on a daily basis. The data from this algorithm provide high-quality satellite information on light output across the globe, allowing scientists to track when – and how brightly – people illuminate the night. A daily global dynamic dataset of nighttime lights is a new way for researchers to understand the broad societal forces impacting energy decisions and to look at how people use cities, from an energy perspective.
