  Title Research on the Influence of Weather Conditions on Urban Night Light Environment Type Journal Article
  Year 2019 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society  
  Volume 54 Issue Pages 101980  
  Keywords Skyglow; Weather; sky brightness; Urban  
  Abstract The increasingly serious urban light pollution has deepened the relevant research, and weather conditions indeed have great impact on the urban night light environment. Based on the SQM instrument, fish-eye camera and weather-related systems, this paper analyzes the changing law of night sky with time and weather. The brightness of the typical clear night sky changes regularly with time, and mainly includes five phases: rapid decline phase, slow decline phase, unstable decline phase, smooth phase, and rapid increase phase of sky brightness. In two phases of the smooth sky brightness, the average sky brightness in the high and low brightness phase respectively is 18.123 mag/arcsecond2 and 18.82 mag/arcsecond2, and about 15 times and 8 times higher than those of the natural night sky. This paper establishes the regression model of typical clear night sky brightness in rapid decline phase and rapid increase phase of sky brightness. The sky magnitude brightness in rainy weather is much lower than that in clear weather, the difference is about 3 mag/arcsecond2, the brightness can be reach 15.63 mag / arcsecond2; the average magnitude brightness in snowy days is about 0.17 mag/arcsecond2 higher than that in cloudy weather. There is a significant correlation among the air quality index, the ground illumination ratio of moon, the atmospheric visibility and the sky brightness. The deepened air pollution can also intensify light pollution, which can increase to 3 and 10 times higher than the night sky brightness under the moderate and severe air pollution. The lunar cycle has the least impact on light pollution in clear days, the sky brightness with the full moon is about 2 and 3 times higher than that without the moon.

  Title Observing Community Resilience from Space: Using Nighttime Lights to Model Economic Disturbance and Recovery Pattern in Natural Disaster Type Journal Article
  Year 2020 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society  
  Volume in press Issue Pages  
  Keywords Remote Sensing  
  Abstract A major challenge for measuring community resilience is the lack of empirical observation in disasters. As an effective tool for observing human activities on the earth surface, night-time light (NTL) remote sensing images can fill the gap of empirical data for measuring community resilience in natural disasters. This study introduces a quantitative framework to model the recovery pattern of economic activity in a natural disaster using the Defense Meteorological Satellite Program-Operational Linescan System (DMSP-OLS) images. The utility of the framework is demonstrated in a case study of Hurricane Katrina, which uncovered the great economic impact of Katrina and spatial variation of the disturbance and recovery pattern of economic activity. Environmental and socio-economic factors that potentially influence the economic recovery were explored in statistical analyses. Instead of a static and holistic index, the framework measures resilience as a dynamic process. The analysis results provide actionable information for prompting resilience in diverse communities and in different phases of a disaster. In addition to Hurricane Katrina, the resilience modeling framework is applicable for other disaster types. The introduced approaches and findings increase our understanding about the complexity of community resilience and provide support for developing resilient and sustainable communities.

  Title Estimating local-scale urban heat island intensity using nighttime light satellite imageries Type Journal Article
  Year 2020 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society  
  Volume 57 Issue Pages in press  
  Keywords Remote Sensing  
  Abstract Urban heat island (UHI) effect tends to harm health, increase anthropogenic energy consumption, and water consumption. Some policies targeting UHI mitigation have been implemented for a few years and thus needs to be evaluated for changes or modifications in the future. A low-cost approach to rapidly monitoring UHI intensity variations can assist in evaluating policy implementations. In this study, we proposed a new approach to local-scale UHI intensity estimates by using nighttime light satellite imageries. We explored to what extent UHI intensity could be estimated according to nighttime light intensity at two local scales. We attempted to estimate district-level and neighbourhood-level UHI intensity across London and Paris. As the geography level rises from district to neighbourhood, the capacity of the models explaining the variations of the UHI intensity decreases. Although the possible presence of residual spatial autocorrelation in the conventional regression models applied to geospatial data, most of the studies are likely to neglect this issue when fitting data to models. To remove negative effects of the residual spatial autocorrelation, this study used spatial regression models instead of non-spatial regression models (e.g., OLS models) to estimate UHI intensity. As a result, district-level UHI intensity was successfully estimated according to nighttime light intensity (approximately R2 = 0.7, MAE =1.16 °C, and RMSE =1.74 °C).

  Title Analysis of Light Pollution in Ticino region during the period 2011-2016 Type Journal Article
  Year 2020 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society  
  Volume 63 Issue Pages 102456  
  Keywords Skyglow  
  Abstract Since 2002, the Environmental Observatory of Southern Switzerland (OASI) has monitored a remarkable set of environmental parameters with the purpose of performing an enhanced observation of the regional environmental conditions. Since 2011, a campaign for the supervision of the artificial nighttime skyglow has been included in the OASI monitoring system exploiting the collaboration with DarkSky association. This network monitors the light pollution in several areas of Ticino, the southernmost Swiss Canton bordering Italy. It consists of multiple stations, which continuously measure the sky brightness. The University of Applied Sciences and Arts of Southern Switzerland, in collaboration with Politecnico di Milano, introduces the results of a study regarding the skyglow evolution during the period 2011-2016. The time-series of the OASI network were pre-processed to detect and discard data affected by natural perturbing events, such as moon and clouds presence and sun effect during twilights. In a second time, a distribution analysis of the data and an evaluation of the brightness trend during the considered period were performed. The results show that light pollution in Ticino is strictly influenced by the northern area of the nearby Italian Lombardy region and that during the surveyed years a decreasing of the pollution occurred.

  Title Circadian Rhythms in Environmental Health Sciences Type Journal Article
  Year 2020 Publication Current Environmental Health Reports Abbreviated Journal Curr Environ Health Rep  
  Volume in press Issue Pages  
  Keywords Review; Human Health; Asthma; Biomarkers; Breast cancer; Circadian rhythms; DNA methylation; Environmental health  
  Abstract PURPOSE OF REVIEW: This review aims to explore how circadian rhythms influence disease susceptibility and potentially modify the effect of environmental exposures. We aimed to identify biomarkers commonly used in environmental health research that have also been the subject of chronobiology studies, in order to review circadian rhythms of relevance to environmental health and determine if time-of-day is an important factor to consider in environmental health studies. Moreover, we discuss opportunities for studying how environmental exposures may interact with circadian rhythms to structure disease pathology and etiology. RECENT FINDINGS: In recent years, the study of circadian rhythms in mammals has flourished. Animal models revealed that all body tissues have circadian rhythms. In humans, circadian rhythms were also shown to exist at multiple levels of organization: molecular, cellular, and physiological processes, including responding to oxidative stress, cell trafficking, and sex hormone production, respectively. Together, these rhythms are an essential component of human physiology and can shape an individual's susceptibility and response to disease. Circadian rhythms are relatively unexplored in environmental health research. However, circadian clocks control many physiological and behavioral processes that impact exposure pathways and disease systems. We believe this review will motivate new studies of (i) the impact of exposures on circadian rhythms, (ii) how circadian rhythms modify the effect of environmental exposures, and (iii) how time-of-day impacts our ability to observe the body's response to exposure.
