  Title The Sky and Sustainable Tourism Development: A Case Study of a Dark Sky Reserve Implementation in Alqueva: The Sky and Sustainable Tourism Development Type Journal Article
  Year 2015 Publication International Journal of Tourism Research Abbreviated Journal Int. J. Tourism Res.  
  Volume 17 Issue 3 Pages 292-302  
  Keywords Society; light pollution; sustainable tourism; rural tourism; Portugal; Alqueva; Dark Sky Reserve  
  Abstract This paper shows the development of a tourism product in a destination that uses the night sky as its main source of attraction. Using this innovative product has helped to create a distinctive image, which is likely to attract a more diverse range of visitors and has assisted in improving economic, social and environmental sustainability. First, we present an overview about sustainable tourism and the sky as a tourism resource followed by a case study, in Portugal, that illustrates the potential of Dark Sky activities for tourism development in rural regions.

  Title Measuring and modelling light pollution at the Zselic Starry Sky Park Type Journal Article
  Year 2010 Publication Journal of Physics: Conference Series Abbreviated Journal J. Phys.: Conf. Ser.  
  Volume 218 Issue Pages 012001  
  Keywords Skyglow; modeling; measurement; SQM; sky brightness; Zselic; International Dark Sky Park; Hungry; measurements; modeling; light pollution; skyglow; radiative transfer  
  Abstract One of the first 'International Dark-sky Parks' in Europe was established at the Zselic Landscape Protection Area in Hungary. A special monitoring program has been carrying on to survey the quality of the night sky using 'Sky Quality Meters' and DSLR cameras. The main conclusion of our measurements is that the local villages have only a minimal effect on the quality of the sky. There are light-domes due to the neighbouring cities only close to the horizon, the main source of obtrusive light is the city of Kaposvár. The anthropogenic component of zenith luminance of the night sky is obtained as the function of the distance from the city centre of Kaposvár. Our data were modelled by radiation transfer calculations. These results can help to draw attention to the energy emitted useless to the space and to protect our nocturnal landscape of nature parks for the next generations.

  Title Modal evaluation of the anthropogenic night sky brightness at arbitrary distances from a light source Type Journal Article
  Year 2015 Publication Journal of Optics Abbreviated Journal J. of Optics  
  Volume 17 Issue Pages 105607  
  Keywords Skyglow; light propagation, atmospheric optics, light pollution  
  Abstract The artificial emissions of light contribute to a high extent to the observed brightness of the night sky in many places of the world. Determining the all-sky radiance of anthropogenic origin requires solving the radiative transfer equation for ground-level light sources, generally resorting to a double-scattering approximation in order to account for the observed radiance patterns with a reasonable degree of accuracy. Since the all-sky radiance distribution produced by an elementary light source depends on the distance to the observer in a way that is not immediately obvious, the contributions of sources located at different distances have to be computed on an individual basis, solving for each one the corresponding scattering integrals. In this paper we show that these calculations may be significantly alleviated by using a modal approach, whereby the hemispheric night-sky radiance is expanded in terms of a convenient basis of two-dimensional (2D) orthogonal functions. Since the modal coefficients of this expansion do vary smoothly with the distance to the observer, the all-sky brightness distributions produced by light sources located at arbitrary intermediate distances can be efficiently estimated by interpolation, provided that the coefficients at a discrete set of distances are accurately determined beforehand.

  Title By the light of the silvery Moon: fact and fiction Type Journal Article
  Year 2013 Publication Physics Education Abbreviated Journal Phys. Educ.  
  Volume 48 Issue 3 Pages 360-367  
  Keywords Vision; moonlight; Purkinje effect; Purkinje shift; mesopic  
  Abstract Is moonlight 'silver' or 'cold'? In this paper we discuss the interesting combination of factors that contribute to the common descriptions of moonlight. Sunlight is reflected from the lunar surface and red-shifted. When traversing the atmosphere, moonlight is further depleted of short wavelength content by Rayleigh scattering. We measured the spectra of the moonlight to show these effects and compared them with sunlight. All measurements, including spectral reflectance, suggest that moonlight is redder than sunlight. The silvery Moon is just an illusion due to the properties and behaviour of our own eyes, including the responses of rods and cones and the physiological perceptive phenomenon called Purkinje shift.

  Title Evaluating nighttime lights and population distribution as proxies for mapping anthropogenic CO2 emission in Vietnam, Cambodia and Laos Type Journal Article
  Year 2019 Publication Environmental Research Communications Abbreviated Journal  
  Volume 1 Issue 9 Pages 091006  
  Keywords Remote Sensing; greenhouse gas emissions; GHG; Asia; Vietnam; Cambodia; Laos; nighttime light  
  Abstract Tracking spatiotemporal changes in GHG emissions is key to successful implementation of the United Nations Framework Convention on Climate Change (UNFCCC). And while emission inventories often provide a robust tool to track emission trends at the country level, subnational emission estimates are often not reported or reports vary in robustness as the estimates are often dependent on the spatial modeling approach and ancillary data used to disaggregate the emission inventories. Assessing the errors and uncertainties of the subnational emission estimates is fundamentally challenging due to the lack of physical measurements at the subnational level. To begin addressing the current performance of modeled gridded CO2 emissions, this study compares two common proxies used to disaggregate CO2 emission estimates. We use a known gridded CO2 model based on satellite-observed nighttime light (NTL) data (Open Source Data Inventory for Anthropogenic CO2, ODIAC) and a gridded population dataset driven by a set of ancillary geospatial data. We examine the association at multiple spatial scales of these two datasets for three countries in Southeast Asia: Vietnam, Cambodia and Laos and characterize the spatiotemporal similarities and differences for 2000, 2005, and 2010. We specifically highlight areas of potential uncertainty in the ODIAC model, which relies on the single use of NTL data for disaggregation of the non-point emissions estimates. Results show, over time, how a NTL-based emissions disaggregation tends to concentrate CO2 estimates in different ways than population-based estimates at the subnational level. We discuss important considerations in the disconnect between the two modeled datasets and argue that the spatial differences between data products can be useful to identify areas affected by the errors and uncertainties associated with the NTL-based downscaling in a region with uneven urbanization rates.
