        <gco:CharacterString xmlns:gco="http://www.isotc211.org/2005/gco">Die Datengrundlage für die satellitenbasierten nächtlichen Lichtemissionen bieten Satellitenbildaufnahmen der VIIRS-Sensoren. Verwendet wurde das wolkenfreie monatliche Komposit aus dem VIIRS Day-Night-Band mit 500 m räumlicher Auflösung am Equator. Die Daten wurden zero-point-korrigiert und liegen in der Einheit nW/cm²/sr vor.
