Title Determinants of efficiency improvement in the Spanish public lighting sector Type Journal Article
Year 2020 Publication Utilities Policy Abbreviated Journal Utilities Policy
Volume 64 Issue Pages 101026
Keywords Lighting; Economics
Abstract This research analyzes the factors that can improve the efficiency of public lighting. First, the annual and inter-annual efficiency levels are calculated. Second, the effects of a set of environmental variables on these efficiency levels are checked with a truncated regression model. The results show that public management is more efficient than private or mixed management. Higher tourism, stronger local governments, and more hours of sunlight appear to improve efficiency. Local governments with the highest budgetary revenues and the most urbanized area experience the greatest improvement in efficiency year after year.

Title Spectral content of artificial lighting and effects on health. Type Journal Article
Year 2011 Publication Journal of the Australasian College of Nutritional and Environmental Medicine Abbreviated Journal
Volume 30 Issue 3 Pages 13-15
Keywords Human Health
Abstract There is an increasing body of evidence indicating possible health effects from prolonged exposure to artificial lighting after dark. Both compact fluorescent lights and light emitting diode lamps have a greater proportion of blue light in the emission spectrum than the older incandescent light sources. Exposure to the blue light component at night has been the subject of ongoing research, with a number of published studies linking blue light content to the disruption of the internal body clock, suppression of melatonin production and various ocular effects. Aside from short-term discomfort, possible health effects include long-term chronic illnesses, including cancer, cardiovascular disease and diabetes. A brief review of recent research is provided, salient health issues are noted and discussed, and some examples of exposure minimisation strategies are suggested.

Title La Palma night-sky brightness Type Report
Year 1998 Publication La Palma Technical Reports Abbreviated Journal
Volume Issue 115 Pages
Keywords Skyglow; solar cycle; airglow; zodiacal light; light pollution; observatories; *Light
Abstract The brightness of the moonless night sky above La Palma was measured on 427 CCD images taken with the Isaac Newton and Jacobus Kapteyn Telescopes on 63 nights during 1987 – 1996. The median sky brightness at high elevation, high galactic latitude and high ecliptic latitude, at sunspot minimum, is B = 22.7, V = 21.9, R = 21.0, similar to that at other dark sites. The main contributions to sky brightness are airglow and zodiacal light. The sky is brighter at low ecliptic latitude (by 0.4 mag); at solar maximum (by 0.4 mag); and at high airmass (0.25 mag brighter at airmass 1.5). Light pollution (line + continuum) contributes < 0.03 mag in U, approximately 0.02 mag in B, approximately 0.10 mag in V, approximately and 0.10 mag in R at the zenith.

Title Advances in using multitemporal night-time lights satellite imagery to detect, estimate, and monitor socioeconomic dynamics Type Journal Article
Year 2017 Publication Remote Sensing of Environment Abbreviated Journal Remote Sensing of Environment
Volume 192 Issue Pages 176-197
Keywords Remote Sensing
Abstract Since the late 1990s, remotely sensed night-time lights (NTL) satellite imagery has been shown to correlate with socioeconomic parameters including urbanization, economic activity, and population. More recent research demonstrates that multitemporal NTL data can serve as a reliable proxy for change over time in these variables whether they are increasing or decreasing. Time series analysis of NTL data is especially valuable for detecting, estimating, and monitoring socioeconomic dynamics in countries and subnational regions where reliable official statistics may be lacking. Until 2012, multitemporal NTL imagery came primarily from the Defense Meteorological Satellite Program – Operational Linescan System (DMSP-OLS), for which digital imagery is available from 1992 to 2013. In October 2011, the launch of NASA/NOAA's Suomi National Polar-orbiting Partnership satellite, whose Visible Infrared Imaging Radiometer Suite (VIIRS) sensor has a Day/Night Band (DNB) specifically designed for capturing radiance from the Earth at night, marked the start of a new era in NTL data collection and applications. In light of these advances, this paper reviews progress in using multitemporal DMSP-OLS and VIIRS imagery to analyze urbanization, economic, and population dynamics across a range of geographic scales. An overview of data corrections and processing for comparison of multitemporal NTL imagery is provided, followed by a meta-analysis and integrative synthesis of these studies. Figures are included that visualize the capabilities of DMSP-OLS and VIIRS to capture socioeconomic change in the post-Soviet Russian Far East and war-torn Syria, respectively. Finally, future directions for NTL research are suggested, particularly in the areas of determining the fundamental causes of observed light and in leveraging VIIRS' superior sensitivity and spatial and radiometric resolution.
