Enhancing nighttime light remote Sensing: Introducing the nighttime light background value (NLBV) for urban applications

open access: yesInternational Journal of Applied Earth Observation and Geoinformation
Artificial light at night, as captured by nighttime light (NTL) remote sensing, typically consists of two components: static urban lighting facilities and dynamic outdoor human activities. Separating these components can improve our understanding of the mechanism underlying NTL remote sensing and broaden its applications.
