  Title Artificial lights and seabirds: is light pollution a threat for the threatened Balearic petrels? Type (down) Journal Article
  Year 2015 Publication The Wilson Journal of Ornithologynithology Abbreviated Journal J. of Ornith.  
  Volume 156 Issue 4 Pages 893-902  
  Keywords Animals; birds; shearwater; Balearic shearwater; Puffinus mauretanicus; Scopoli's shearwater; Calonectris diomedea; European storm-petrel; Hydrobates pelagicus; Balearic Islands; Mediterranean; light pollution; biology; ecology; conservation  
  Abstract Petrels are among the most threatened group of birds. On top of facing predation by introduced mammals and incidental bycatch, these seabirds have to deal with an emerging threat, light pollution, which is increasing globally. Fledglings are disoriented and attracted to artificial lights in their maiden night flights from their nests to the sea. Once grounded, they are exposed to multiple threats leading to high mortality. We report on numbers of three petrel species (Balearic shearwater Puffinus mauretanicus, Scopoli's shearwater Calonectris diomedea, and European storm-petrel Hydrobates pelagicus) rescued on the Balearic Islands, Mediterranean Sea, in the period 1999-2013. We assessed the proportion of grounded fledglings in the population and colonies impact based on radiance levels measured from a nocturnal satellite image. We also calculated the radius of light pollution impact. At least 304 fledgling birds were found stranded due to attraction to artificial lights, fatally affecting 8.5 % of them. The proportion of grounded fledglings ranged between 0.13 and 0.56 % of the fledglings produced annually. The body mass of Balearic and Scopoli's shearwater fledglings decreased with rescue date. Light-induced mortality increased during the fledging period for Scopoli's shearwaters. Birds were rescued at a mean distance of 4833 m from the nearest colony, and between 30 and 47 % of colonies were exposed to light-polluted areas. Although impact seems to be low for all species, urban development and, consequently, the increase in light pollution in the proximity of the colonies should be taken into account to reduce as much as possible this emerging source of mortality.

  Title Dark Sky Parks – new impulse for nature tourism development in protected areas (National Park Muranska Planina, Slovakia) Type (down) Journal Article
  Year 2016 Publication e-Review of Tourism Research Abbreviated Journal eRTR  
  Volume 13 Issue 5/6 Pages 536-549  
  Keywords Society; tourism; astrotourism; sustainable tourism; dark sky parks  
  Abstract Dark Sky Parks are one of important measures to support nature tourism in the protected

areas. In this paper, we introduce the concept of astro-tourism on the model area of National Park Muranska Planina (Slovakia), which should lead to the establishment of Dark Sky Park and the implementation of measures focused on dark sky protection, i.e. the elimination of light pollution over model area. The concept includes the measurement of night sky brightness, the selection of suitable observational sites and lighting plan. It is very important from the view of ecology, e.g. by the protection of night animal species. On the other hand, these characteristics can be fully used in new tourism concept in that protected area.

  Title “Astronomical Tourism”: The Astronomy and Dark Sky Program at Bryce Canyon National Park Type (down) Journal Article
  Year 2013 Publication Tourism Management Perspectives Abbreviated Journal Tourism Management Perspectives  
  Volume 7 Issue Pages 1-15  
  Keywords Astronomy-related tourism; National parks; Night sky darkness; astrotourism; dark skies  
  Abstract Astronomical tourism represents a less-studied segment of sustainable tourism, where a dark night sky is the underlying resource. This article evaluates an astronomical tourism program, in this case at a national park with dark skies for observing. Bryce Canyon National Park (BCNP) in the southwestern United States has a well-developed astronomy program to serve visitors. The program consists of solar viewing during the day, multimedia evening programs, and night-time star gazing with telescopes. Depending on the specific measure used, it appears that up to 10% of park visitors may be involved with the formal Astronomy and Dark Sky Program and/or more informal astronomy activities. BCNP appears well positioned to take advantage of the dark sky attributes of the park and to educate visitors about the importance of maintaining and/or increasing the darkness of night skies. Potential future developments in the program may serve to further increase the number of visitors to BCNP.

  Title Where Does Nighttime Light Come From? Insights from Source Detection and Error Attribution Type (down) Journal Article
  Year 2020 Publication Remote Sensing Abbreviated Journal Remote Sensing  
  Volume 12 Issue 12 Pages 1922  
  Keywords Remote Sensing  
  Abstract Nighttime light remote sensing has aroused great popularity because of its advantage in estimating socioeconomic indicators and quantifying human activities in response to the changing world. Despite many advances that have been made in method development and implementation of nighttime light remote sensing over the past decades, limited studies have dived into answering the question: Where does nighttime light come from? This hinders our capability of identifying specific sources of nighttime light in urbanized regions. Addressing this shortcoming, here we proposed a parcel-oriented temporal linear unmixing method (POTLUM) to identify specific nighttime light sources with the integration of land use data. Ratio of root mean square error was used as the measure to assess the unmixing accuracy, and parcel purity index and source sufficiency index were proposed to attribute unmixing errors. Using the Visible Infrared Imaging Radiometer Suite (VIIRS) nighttime light dataset from the Suomi National Polar-Orbiting Partnership (NPP) satellite and the newly released Essential Urban Land Use Categories in China (EULUC-China) product, we applied the proposed method and conducted experiments in two China cities with different sizes, Shanghai and Quzhou. Results of the POTLUM showed its relatively robust applicability of detecting specific nighttime light sources, achieving an rRMSE of 3.38% and 1.04% in Shanghai and Quzhou, respectively. The major unmixing errors resulted from using impure land parcels as endmembers (i.e., parcel purity index for Shanghai and Quzhou: 54.48%, 64.09%, respectively), but it also showed that predefined light sources are sufficient (i.e., source sufficiency index for Shanghai and Quzhou: 96.53%, 99.55%, respectively). The method presented in this study makes it possible to identify specific sources of nighttime light and is expected to enrich the estimation of structural socioeconomic indicators, as well as better support various applications in urban planning and management.

  Title Licht über Wien VII Type (down) Journal Article
  Year 2020 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords Skyglow; Energy  
  Abstract 231. Auf einen BlickDie Helligkeit des Wiener Nachthimmels hat sich stabilisiert. 2019 ist das zweite Jahr in Folge, in dem die Energie desLichts über Wien um weniger als 5 % zugenommen hat. Die Menge des künstlichen Lichts über Wien hat sich nach dem steilem Anstieg der Jahre 2009 bis 2014 auf hohem Niveau eingependelt..Es besteht ein enger Zusammenhang zwischen Licht- und Luftverschmutzung. Über 10 Jahre bestehende Korrelationen von Lichtimmissions- und Luftgüteindikatoren bestätigen dies. Auf dieser Erkenntnis beruht eine auf standardisierte Luft-güte-Bedingungen normierte Angabe der Globalstrahlung, mit der direkter auf die von der Stadt eingebrachten Lichtmenge geschlossen werden kann.Der Kunstlichthalo über Wien wurde mit einer neuen Methode vollständiger berechnet und enthält demnach deutlich mehr Energie als bisher angenommen. 500 Gigawattstunden und 100.000 Tonnen CO2-Äquivalent pro Jahr müssen als typischer Wert für eine Untergrenze angenommen werden.
