Title Potentiality of Using Luojia 1-01 Nighttime Light Imagery to Investigate Artificial Light Pollution Type Journal Article
Year 2018 Publication Sensors Abbreviated Journal Sensors
Volume 18 Issue 9 Pages 2900
Keywords Remote Sensing; Instrumentation
Abstract The successful launch of Luojia 1-01 complements the existing nighttime light data with a high spatial resolution of 130 m. This paper is the first study to assess the potential of using Luojia 1-01 nighttime light imagery for investigating artificial light pollution. Eight Luojia 1-01 images were selected to conduct geometric correction. Then, the ability of Luojia 1-01 to detect artificial light pollution was assessed from three aspects, including the comparison between Luojia 1-01 and the Suomi National Polar-Orbiting Partnership Visible Infrared Imaging Radiometer Suite (NPP-VIIRS), the source of artificial light pollution and the patterns of urban light pollution. Moreover, the advantages and limitations of Luojia 1-01 were discussed. The results showed the following: (1) Luojia 1-01 can detect a higher dynamic range and capture the finer spatial details of artificial nighttime light. (2) The averages of the artificial light brightness were different between various land use types. The brightness of the artificial light pollution of airports, streets, and commercial services is high, while dark areas include farmland and rivers. (3) The light pollution patterns of four cities decreased away from the urban core and the total light pollution is highly related to the economic development. Our findings confirm that Luojia 1-01 can be effectively used to investigate artificial light pollution. Some limitations of Luojia 1-01, including its spectral range, radiometric calibration and the effects of clouds and moonlight, should be researched in future studies.

Title Mapping ambient light at night using field observations and high-resolution remote sensing imagery for studies of urban environments Type Journal Article
Year 2018 Publication Building and Environment Abbreviated Journal Building and Environment
Volume 145 Issue Pages 104-114
Keywords Remote Sensing
Abstract Artificial lighting allows for a variety of activities to take place in the absence of sunlight, but also has an increasingly recognized range of negative social and health-related effects. For studies of urban ambient light at night (ALN), objective and standardized data on the amount of ALN experienced by people is often unavailable at the necessary intra-urban spatial scale. In this paper, we outline options for producing such data through (1) field observations acquired with a luminance meter mounted on a vehicle, (2) a 1-m resolution image mosaic produced from a dedicated aerial survey, and (3) a 50-m resolution image taken from the International Space Station. We produce two remote sensing-derived maps of ALN for a large urban area in Canada, and compare their spatial detail to the World Atlas of Artificial Night Sky Brightness, a publicly available alternative data source. Convergent validity with field observations suggests that both mapping approaches can be used to quantify the amount of light humans are exposed to at night, at different locations across a large urban area, and may thus aid in further studying the varied effects of artificial nighttime lighting.

Title Impact of a shift work-like lighting schedule on the functioning of the circadian system in the short-lived fish Nothobranchius furzeri Type Journal Article
Year 2018 Publication Experimental Gerontology Abbreviated Journal Exp Gerontol
Volume in press Issue Pages in press
Keywords Animals
Abstract Adult Nothobranchius furzeri of the MZM-04/10 strain were individually kept and subjected to a “5+2” shifting lighting schedule (SHIFT) for 8weeks in order to evaluate the desynchronizing effects of a simulated human-like shift-work schedule on the functioning of the circadian system (CS). With this aim, sixteen 21-week-old N. furzeri were placed into a Morning, Night and Evening schedule (lights on from 08:00 to 16:00, 00:00 to 08:00 and 16:00 to 00:00h, respectively) and fed once a day in the middle of the corresponding photophase (12:00, 04:00 and 20:00h, respectively). Then, in the weekends (2days), fish were always returned to the Morning shift. As controls, 16 fish were maintained under a non-shifting LD cycle condition (CONTROL) throughout the whole experiment, with lights on from 08:00 to 16:00h. Rest-activity rhythm (RAR) of fish subjected to SHIFT showed several symptoms of chronodisruption, such as a decrease in the percentage of diurnal activity and a reduction of the relative amplitude and the circadian function index with time. When a periodogram analysis was performed, RAR of N. furzeri under SHIFT conditions showed up to three separate circadian components: one longer than 24h (26.5h) that followed the weekly 8h delays; a short-period component (~23h) that was related to the weekend's phase advances, and finally, a 24h component. The shifting LD schedule also affected fish CS at a molecular level, with several significant differences in the expression of core genes of the molecular clock (bmal1, clock, roralpha, rev-erbalpha) between SHIFT and CONTROL animals. RAR impairment along with changes in clock gene expression could be associated with high stress and accelerated aging in these fish.

Title Illuminance Reconstruction of Road Lighting in Urban Areas for Efficient and Healthy Lighting Performance Evaluation Type Journal Article
Year 2018 Publication Applied Sciences Abbreviated Journal Applied Sciences
Volume 8 Issue 9 Pages 1646
Keywords Instrumentation; Lighting; Planning
Abstract Big lighting data are required for evaluation of lighting performance and impacts on human beings, environment, and ecology for smart urban lighting. However, traditional approaches of measuring road lighting cannot achieve this aim. We propose a rule-of-thumb model approach based on some feature points to reconstruct road lighting in urban areas. We validated the reconstructed illuminance with both software simulated and real road lighting scenes, and the average error is between 6 and 19%. This precision is acceptable in practical applications. Using this approach, we reconstructed the illuminance of three real road lighting environments in a block and further estimated the mesopic luminance and melanopic illuminance performance. In the future, by virtue of Geographic Information System technology, the approach may provide big lighting data for evaluation and analysis, and help build smarter urban lighting.

Title Conservation du ciel nocturne : surveillance de l’éclairage extérieur et de la pollution lumineuse au parc national et à la Réserve internationale de ciel étoilé du Mont-Mégantic Type Journal Article
Year 2018 Publication Le Naturaliste canadien Abbreviated Journal Le Naturaliste canadien
Volume 142 Issue 3 Pages 88
Keywords Skyglow
Abstract English:

Although seemingly unchanging, today, our ability to see stars on a dark night is in danger of disappearing. The reason for this is the widespread growth of light pollution from inadequate lighting systems. This study, which used a range of methods, presents the results of light pollution measurements taken within the Mont-Mégantic International Dark Sky Reserve (MMIDSR), which was created in 2007 to protect the quality of astronomical observations and research at the Mont-Mégantic Observatory, and to preserve the exceptional starry nightscape visible from the site. Two essential elements of artificial night lighting were considered: its source and its diffusion in the atmosphere. Analyses showed that despite a global trend towards an increase in light levels, population growth on the outskirts of the Parc national du Mont-Mégantic, and the arrival of problematic types of lighting fixtures on the market, the level of light pollution in the MMIDSR has remained stable over the last 10 years, not only at the zenith but across the entire sky.

French:

Pourtant d’apparence immuable, le ciel étoilé est aujourd’hui menacé de disparition. La cause est la croissance généralisée de la pollution lumineuse, résultat de l’utilisation de dispositifs d’éclairage inadéquats. Nous présentons ici les résultats de la mesure de cette pollution obtenue par différentes approches méthodologiques sur le territoire de la Réserve internationale de ciel étoilé du Mont-Mégantic (RICEMM). La RICEMM a été créée en 2007 afin de protéger la qualité des observations astronomiques et de recherche de l’observatoire du mont Mégantic, ainsi que pour conserver les paysages étoilés exceptionnels du site. Deux aspects incontournables de la lumière artificielle nocturne ont été pris en compte : ses sources, ainsi que sa diffusion dans l’atmosphère. Les analyses démontrent que le niveau de pollution lumineuse est resté stable depuis 10 ans dans la RICEMM, tant au zénith que pour l’ensemble du ciel, et ce, malgré une tendance mondiale à la hausse des niveaux d’éclairement, l’augmentation de la population dans la périphérie du parc national du Mont-Mégantic et l’arrivée sur le marché de types de luminaires problématiques.
