Downscaling NPP–VIIRS Nighttime Light Data Using Vegetation Nighttime Condition Index

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Nighttime light (NTL) data, a cornerstone in the scientific community, are widely used across various disciplines. However, the spatial resolution of the commonly used NTL datasets often falls coarse for detailed urban-scale analyses. Current downscaling

Light Pollution Reduction in Nighttime Photography

open access: yesCoRR, 2021
Nighttime photographers are often troubled by light pollution of unwanted artificial lights. Artificial lights, after scattered by aerosols in the atmosphere, can inundate the starlight and degrade the quality of nighttime images, by reducing contrast and dynamic range and causing hazes.

Evaluation of Light Pollution in Global Protected Areas from 1992 to 2018

open access: yesRemote Sensing, 2021
Light pollution, a phenomenon in which artificial nighttime light (NTL) changes the form of brightness and darkness in natural areas such as protected areas (PAs), has become a global concern due to its threat to global biodiversity.

Dynamic threats of nighttime light-represented human activities to giant pandas and their habitat

open access: yesFrontiers in Environmental Science, 2022
Human activities are one of the main factors threatening the long-term survival of wild giant pandas. Long-term and large-scale human activities can be quickly assessed by night light remote sensing data, which has been more and more widely used. In this

Urban Nighttime Leisure Space Mapping with Nighttime Light Images and POI Data [PDF]

open access: yesRemote Sensing, 2020
Urban nighttime leisure spaces (UNLSs), important urban sites of nighttime economic activity, have created enormous economic and social benefits. Both the physical features (e.g., location, shape, and area) and the social functions (e.g., commercial streets, office buildings, and entertainment venues) of UNLSs are important in UNLS mapping.

Estimating Local Inequality from Nighttime Lights [PDF]

open access: yesRemote Sensing, 2021
Economic inequality at the local level has been shown to be an important predictor of people’s political perceptions and preferences. However, research on these questions is hampered by the fact that local inequality is difficult to measure and systematic data collections are rare, in particular in countries of the Global South.

New Composite Nighttime Light Index (NCNTL): A New Index for Urbanization Evaluation Research

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
This article employs the 2018 National Polar-Orbiting Partnership/Visible Infrared Imaging Radiometer Suite (NPP/VIIRS) and Luojia_01 nighttime light imagery to construct a New Composite Nighttime Light Index, which is NCNTL.

Dynamics and spatial distribution of global nighttime lights [PDF]

open access: yesEPJ Data Science, 2013
Using open source data, we observe the fascinating dynamics of nighttime light. Following a global economic regime shift, the planetary center of light can be seen moving eastwards at a pace of about 60 km per year. Introducing spatial light Gini coefficients, we find a universal pattern of human settlements across different countries and see a global ...

Nighttime luminosity transitions are tightly spatiotemporally correlated with land use changes: A pixelwise case study in Beijing, China

open access: yesEcological Indicators, 2022
Nighttime light data and land use data derived from remote sensing satellites are commonly used to monitor human activities on the Earth. A thorough understanding of the spatiotemporal interactions between these data enables better characterization and ...
