Grid-Scale Poverty Assessment by Integrating High-Resolution Nighttime Light and Spatial Big Data—A Case Study in the Pearl River Delta

open access: yesRemote Sensing, 2023
Poverty is a social issue of global concern. Although socioeconomic indicators can easily reflect poverty status, the coarse statistical scales and poor timeliness have limited their applications.

Downscaling satellite night-time lights imagery to support within-city applications using a spatially non-stationary model

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2023
For mapping and monitoring socioeconomic activities in cities, night-time lights (NTL) satellite sensor images are used widely, measuring the light intensity during the night.

Luojia-1 Nightlight Image Registration Based on Sparse Lights

open access: yes, 2022
When mosaicking adjacent nightlight images of a large area that lacks human activities, traditional registration methods have difficulty realizing the tie point registrations due to the lack of structural information. In order to address this issue, this

Monte Carlo Simulation of 3D Cloud Radiance Distributions Affected by Ground‐Based Lighting

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Satellite observations of artificial light sources at night are increasing. Clouds, as the most important radiative modulators in the Earth‐atmosphere system, significantly influence the observed values and spatial distribution of the artificial light coming from the ground.

ED‐Autoformer: A New Model for Precise Global TEC Forecast

open access: yesSpace Weather, Volume 23, Issue 6, June 2025.
Abstract Total electron content (TEC) is a key parameter for characterizing ionospheric morphology and significantly impacts the Global Navigation Satellite System. The ionosphere responds dramatically to solar and geomagnetic activity, leading to substantial TEC fluctuations and disturbances.

How dark is a river? Artificial light at night in aquatic systems and the need for comprehensive night‐time light measurements

open access: yesWIREs Water, Volume 6, Issue 6, November/December 2019., 2019
Artificial light at night can occur as a form of environmental pollution, light pollution, which also affects aquatic systems. We identify a knowledge gap of insufficient data regarding the status quo of aquatic light pollution and provide a route to fill this gap with in‐situ measurements.
