Machine-Learning-Based Monitoring of Night Sky Brightness Using Sky Quality Meters and Multi-Source Remote Sensing

Remote Sensing, Journal Year: 2025, Volume and Issue: 17(8), P. 1332 - 1332

Published: April 8, 2025

With the rapid pace of urbanization, light pollution has emerged as a critical environmental issue. Evaluating and managing effectively is challenging, traditional monitoring methods often fail to capture its spatial distribution driving factors comprehensively. To address this limitation, study integrates Sky Quality Meter (SQM) observational data from three diverse locations—Chaozhou (China), Urumqi Ghent (Belgium)—with multi-source remote sensing construct predictive models night sky brightness (NSB) using machine learning approaches. Among tested models, voting ensemble model demonstrated superior performance, achieving high accuracy robust generalization across regional datasets. The generated local-scale NSB maps reveal substantial variations in pollution, highlighting influence local anthropogenic factors. By combining learning, offers scalable efficient method for evaluating levels at scales. findings underscore value these providing actionable insights mitigation management strategies, supporting efforts reduce adverse impacts on environment society.

Toward a Spectrophotometric Characterization of the Chilean Night Sky. A First Quantitative Assessment of ALAN across the Coquimbo Region

The Astronomical Journal, Journal Year: 2024, Volume and Issue: 167(2), P. 67 - 67

Published: Jan. 19, 2024

Abstract Light pollution is recognized as a global issue that, like other forms of anthropogenic pollution, has significant impact on ecosystems and adverse effects living organisms. Plentiful evidence suggests that it been increasing at an unprecedented rate all spatial scales. Chile—which, thanks to its unique environmental conditions, become one the most prominent astronomical hubs world—seems be no exception. In this paper we present results first observing campaign aimed quantifying artificial lights night brightness colors Chilean sky. Through analysis photometrically calibrated all-sky images captured four representative sites with degree anthropization, comparison state-of-the-art numerical models, show levels light have already altered appearance natural sky even in remote areas. Our observations reveal level recorded small town Coquimbo Region comparable Flagstaff, Arizona, ten times larger Dark Sky city, mid-size urban area gateway Atacama Desert displays photometric indicators quality are typical densely populated regions Europe. suggest there still much done Chile keep under control thus preserve darkness sky—a cultural heritage our responsibility protect.

The effects of acoustic-light-thermal environment quality parameters on pedestrians’ overall comforts in residential districts

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Aug. 23, 2024

This study explored subjective responses towards various environmental quality parameters. It would be helpful to approach an overall comfort improvement relating physics. In order investigate the combined effects of sound, light and heat on pedestrians, which could evaluated by vote, two residential areas in Yubei District, Chongqing (a Cfa city China) were selected for field measurements questionnaires. Three three key findings concluded based parameters via multiple linear regression. First, average outdoor neutral temperature, mean sound level illumination intensity determined 26.6 °C (determined physiologically equivalent temperature), 56.5 dBA A-weighted continuous level) 21.4 klx LUX), respectively. Second, considering both physiology psychology, thermal perceptions varied acoustic environments. Residents partially had lower temperatures at noisy condition. Third, factors a significant effect comfort. Positive correlation between temperature vote was found (sig < 0.000); while pressure not always significant. Hence, stress played role people's has environment human perceptions. provided better understanding against dwellers' feelings under complex circumstances.

Artificial Light at Night and Type 2 Diabetes Mellitus

Diabetes & Metabolism Journal, Journal Year: 2024, Volume and Issue: 48(5), P. 847 - 863

Published: Sept. 13, 2024

The widespread and pervasive use of artificial light at night (ALAN) in our modern 24-hour society has emerged as a substantial disruptor natural circadian rhythms, potentially leading to rise unhealthy lifestyle-related behaviors (e.g., poor sleep; shift work). This phenomenon been associated with an increased risk type 2 diabetes mellitus (T2DM), which is pressing global public health concern. However, date, reviews summarizing associations between ALAN T2DM have primarily focused on the limited characteristics exposure intensity) ALAN. literature review extends beyond prior by consolidating recent studies from 2000 2024 regarding both indoor outdoor incidence or prevalence T2DM. We also described potential biological mechanisms through modulates glucose metabolism. Furthermore, we outlined knowledge gaps investigated how various only intensity (including type, timing, duration, wavelength, individual sensitivity) influence risk. Recognizing detrimental impact sleep behavioral correlates physical activity dietary patterns, additionally summarized investigating mediating role each component relationship Lastly, proposed implications chronotherapies chrononutrition for management context exposure.

Exploring Community Self-efficacy to Light Pollution Mitigation in A Tourism Destination

Tourism Planning & Development, Journal Year: 2024, Volume and Issue: 21(6), P. 818 - 840

Published: March 19, 2024

Light pollution is an emergent environmental concern, it disrupts the natural patterns of wildlife, contributes to increase in carbon dioxide atmosphere, human sleep, and obscures stars night sky. However, rural urban communities often overlook this factor, since not seen as a problem, even if destination has taken measures mitigate light pollution, still challenging maintain optimal levels. This study applied questionnaire (N = 366) examine community involvement mitigation Portuguese tourism 2023. Results demonstrated that sufficient incentive for participants take individual (β 0.075, p 0.243). they consider integrating with at local level could enhance tourist experience 0.427, 0.000). Tourism destinations should promote education about effects pollution.
