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

open access: yesInternational Journal of Applied Earth Observations 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.

Indian economy and Nighttime Lights [PDF]

open access: yes2021 International Conference on Computational Intelligence and Knowledge Economy (ICCIKE), 2021
Forecasting economic growth of India has been traditionally an uncertain exercise. The indicators and factors affecting economic structures and the variables required to model that captures the situation correctly is point of concern. Although the forecast should be specific to the country we are looking at however countries do have interlinkages among

The Annual Cycling of Nighttime Lights in India [PDF]

open access: yesRemote Sensing, 2021
India is known to have unstable power supply, and many locations show an annual cycle in VIIRS Nighttime Light (VNL). In this study, autocorrelation function (ACF) analysis is used to identify the annual cycling in VNL. Two fundamentally different classification techniques are proposed to classify the ACF profile into one of the three arch types, i.e.,

First Nighttime Light Spectra by Satellite—by EnMAP [PDF]

open access: yesRemote Sensing, 2023
For the first time VIS/NIR-SWIR (visible and near infrared – shortwave infrared) nighttime spectra of a satellite mission are analyzed, using the EnMAP (Environmental Mapping and Analysis Program) high-resolution imaging spectrometer. The focus of this article is set on the spectral characteristics.

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

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.

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.
