Title Association between outdoor light-at-night exposure and colorectal cancer in Spain (MCC-Spain study) Type Journal Article
Year (down) 2020 Publication Epidemiology (Cambridge, Mass.) Abbreviated Journal Epidemiology
Volume in press Issue Pages
Keywords Human Health; Remote Sensing
Abstract BACKGROUND: Night shift work, exposure to artificial light-at-night and particularly blue light spectrum, and the consequent circadian disruption may increase the risk of breast and prostate cancer. Colorectal cancer risk may also be increased among night-shift workers. We investigated the association between exposure to artificial light at night according to light spectrum and colorectal cancer among subjects who had never worked at night in a general population case-control study in Spain. METHODS: We examined information on 661 incident histologically verified colorectal cancer cases and 1322 controls from Barcelona and Madrid, 2007-2013. Outdoor artificial light at night exposure was based on images from the International Space Station (ISS) including data on remotely sensed upward light intensity. We derived adjusted odds ratio (OR) estimates and confidence intervals (CI) for visual light, blue light, and spectral sensitivities of the five human photopigments assigned to participant's geocoded longest residence. RESULTS: : Exposure to blue light spectrum was positively associated with colorectal cancer (OR=1.6; 95%CI: 1.2-2.2; highest vs. lowest tertile). ORs were similar (OR=1.7; 95%CI: 1.3-2.3) when further adjusting for area socioeconomic status, diet patterns, smoking, sleep and family history. We observed no association for outdoor visual light (full spectrum) (OR = 1.0, 95%CI 0.7-1.2; highest vs. lowest tertile). Analysis of the five photopigments gave similar results with increased risks for shorter wavelengths overlapping with the blue spectrum and no association for longer wavelengths. CONCLUSIONS: Outdoor blue light spectrum exposure that is increasingly prevalent in recent years may be associated with colorectal cancer risk.

Title Outdoor light at night, air pollution and depressive symptoms: A cross-sectional study in the Netherlands Type Journal Article
Year (down) 2020 Publication Science of The Total Environment Abbreviated Journal Science of The Total Environment
Volume in press Issue Pages 140914
Keywords Remote Sensing; Human Health
Abstract Background

Artificial light at night (ALAN) may be an anthropogenic stressor for mental health disturbing humans' natural day–night cycle. However, the few existing studies used satellite-based measures of radiances for outdoor ALAN exposure assessments, which were possibly confounded by traffic-related air pollutants.

Objective

To assess 1) whether living in areas with increased exposure to outdoor ALAN is associated with depressive symptoms; and 2) to assess the potential confounding effects of air pollution.

Methods

We used cross-sectional data from people (N = 10,482) aged 18–65 years in the Netherlands. Depressive symptoms were assessed with the Patient Health Questionnaire (PHQ–9). Satellite-measured annual ALAN were taken from the Visible Infrared Imaging Radiometer Suite. ALAN exposures were assessed at people's home address within 100 and 600 m buffers. We used generalized (geo)additive models to quantify associations between PHQ–9 scores and quintiles of ALAN adjusting for several potential confounders including PM2.5 and NO2.

Findings

Unadjusted estimates for the 100 m buffers showed that people in the 2nd to 5th ALAN quintile showed significantly higher PHQ–9 scores than those in the lowest ALAN quintile (βQ2 = 0.503 [95% confidence interval, 0.207–0.798], βQ3 = 0.587 [0.291–0.884], βQ4 = 0.921 [0.623–1.218], βQ5 = 1.322 [1.023–1.620]). ALAN risk estimates adjusted for individual and area-level confounders (i.e., PM2.5, urbanicity, noise, land-use diversity, greenness, deprivation, and social fragmentation) were attenuated but remained significant for the 100 m buffer (βQ2 = 0.420 [0.125–0.715], βQ3 = 0.383 [0.071–0.696], βQ4 = 0.513 [0.177–0.850], βQ5 = 0.541 [0.141–0.941]). When adjusting for NO2 per 100 m buffers, the air pollutant was associated with PHQ–9 scores, but ALAN did not display an exposure-response relationship. ALAN associations were insignificance for 600 m buffers.

Interpretation

Accounting for NO2 exposure suggested that air pollution rather than outdoor ALAN correlated with depressive symptoms. Future evaluations of health effects from ALAN should consider potential confounding by traffic-related exposures (i.e., NO2).

Title Lichtverschmutzung – Ausmaß, gesellschaftliche und ökologische Auswirkungen sowie Handlungsansätze Type Report
Year (down) 2020 Publication Abbreviated Journal
Volume 186 Issue Pages 1-200
Keywords Review; Skyglow; Ecology; Human Health; Lighting; Public Safety; Remote Sensing
Abstract Künstliches Licht kann als eine der größten technischen Errungenschaften der Menschheit angesehen werden, die erhebliche Veränderungen bzw. Fortschritte der Arbeits- und Lebensweisen ermöglichen. Mit künstlicher Beleuchtung wird aber auch der natürliche Rhythmus von Tag und Nacht verändert und damit das Gesamtgefüge des Naturhaushaltes und der Nachtlandschaft transformiert. Ein natürlich dunkler Nachthimmel ist in Deutschland selten geworden. Licht-glocken über urbanen Gebieten sind weit weg von ihrem Entstehungsort in unbeleuchteten Gebieten noch sichtbar und lassen Sterne und die Milchstraße unkenntlich werden. Nicht nur das direkte elektrische Licht erleuchtet unsere Umwelt, sondern auch der nach oben abgestrahlte und reflektierte Teil des Lichts. Schichten der Atmosphäre, Staub oder Wassertropfen reflektieren und streuen das Licht. Dieser auch als Skyglow bezeichnete Effekt bewirkt eine zusätzliche Erhellung. Neben dieser künstlich erhöhten Himmelshelligkeit kann Licht auch die direkte Umgebung ungewollt aufhellen oder durch Blendung das Sehen einschränken. Licht ist ein wichtiger externer Zeitgeber für die innere Uhr der Lebewesen, an dessen natürlichen Rhythmus sich Menschen, Tiere und Pflanzen über Jahrhunderte angepasst haben. So wird vermutet, dass die permanent und periodisch veränderten Lichtverhältnisse durch zunehmende künstliche Beleuchtung negative Auswirkungen auf die menschliche Gesundheit haben und ebenso zu ökologischen Beeinträchtigungen führen.All diese nichtintendierten Wirkungen der künstlichen Beleuchtung werden unter dem Sammelbegriff Lichtverschmutzung verstanden. Lichtverschmutzung ist hier definiert als unerwünschte Wirkung künstlicher Beleuchtung im Außenbereich, also das Licht, das räumlich (Richtung und Fläche), zeitlich (Tages- und Jahreszeit, Dauer, Periodizität) oder in der Intensität oder spektralen Zusammensetzung (z.B. Ultraviolett- oder Blauanteil) über den reinen Beleuchtungszweck hinaus nicht beabsichtigte Auswirkungen hat (Kuechly et al. 2018). Mit dem vorliegenden Bericht werden der wissenschaftliche Erkenntnis-stand im Hinblick auf Umfang und Trends der Lichtverschmutzung sowie ihre wirtschaftlichen und soziokulturellen, humanmedizinischen und ökologischen Wirkungen zusammengefasst. Auf Basis dieser Erkenntnisse und aktueller beleuchtungstechnologischer und lichtplanerischer Möglichkeiten werden Handlungsoptionen abgeleitet, die eine Verringerung der Lichtverschmutzung bei gleichzeitiger Berücksichtigung der nutzbringenden Ziele der Beleuchtung unterstützen können.

Title Estimating spatiotemporal dynamics of county-level fossil fuel consumption based on integrated nighttime light data Type Journal Article
Year (down) 2020 Publication Journal of Cleaner Production Abbreviated Journal Journal of Cleaner Production
Volume in press Issue Pages 123427
Keywords Remote Sensing
Abstract Rapid urbanization has resulted in increased fossil fuel consumption in China, which is closely related to regional sustainable development and CO2 emissions. This study proposed an improved model to estimate fossil fuel consumption on the county scale in Shandong to understand the dynamics of fossil fuel consumption. This improved model is beneficial for establishing energy-saving and CO2 emission reduction policies for both Shandong and other regions in China. Because of the lack of data on a county scale, this study applied panel data analysis from 1992 to 2017 by integrating the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) and NPP-VIIRS (Suomi National Polar-Orbiting Partnership satellite with the Visible Infrared Imaging Radiometer Suit) nighttime light data. Results showed that (1) The new method performed better than previous methods on estimating fossil fuel consumption; (2) Fossil fuel consumption has been rapidly growing in all cities and most districts and counties, mainly concentrated in west and east central Shandong; (3) Regions with high fossil fuel consumption shifted from west central Shandong to east central on the city level, and expanded from the east central to the entire central region on the county level; (4) In regions with a lower level of development, fossil fuel consumption tended to grow faster. These results will improve the understanding of fossil fuel consumption over the long term on county scales, and are beneficial for creating policies on regional energy savings and CO2 emission reduction.

Title Cloud Detection For Night-Time Panchromatic Visible And Near-Infrared Satellite Imagery Type Journal Article
Year (down) 2020 Publication ISPRS Annals of Photogrammetry, Remote Sensing and Spatial Information Sciences Abbreviated Journal ISPRS Ann. Photogramm. Remote Sens. Spatial Inf. Sci.

Abstract Cloud detection for night-time panchromatic visible and near-infrared (VNIR) satellite imagery is typically performed based on synchronized observations in the thermal infrared (TIR). To be independent of TIR and to improve existing algorithms, we realize and analyze cloud detection based on VNIR only, here NPP/VIIRS/DNB observations. Using Random Forest for classifying cloud vs. clear and focusing on urban areas, we illustrate the importance of features describing a) the scattering by clouds especially over urban areas with their inhomogeneous light emissions and b) the normalized differences between Earth’s surface and cloud albedo especially in presence of Moon illumination. The analyses substantiate the influences of a) the training site and scene selections and b) the consideration of single scene or multi-temporal scene features on the results for the test sites. As test sites, diverse urban areas and the challenging land covers ocean, desert, and snow are considered. Accuracies of up to 85% are achieved for urban test sites.
