Title Night-time lights are more strongly related to urban building volume than to urban area Type Journal Article
Year (down) 2020 Publication Remote Sensing Letters Abbreviated Journal Remote Sensing Letters
Volume 11 Issue 1 Pages 29-36
Keywords Remote Sensing; Urban; Night Lights
Abstract A strong relationship between night-time light (NTL) data and the areal extent of urbanized regions has been observed frequently. As urban regions have an important vertical dimension, it is hypothesized that the strength of the relationship with NTL can be increased by consideration of the volume rather than simply the area of urbanized land. Relationships between NTL and the area and volume of urbanized land were determined for a set of towns and cities in the UK, the conterminous states of the USA and countries of the European Union. Strong relationships between NTL and the area urbanized were observed, with correlation coefficients ranging from 0.9282 to 0.9446. Higher correlation coefficients were observed for the relationship between NTL and urban building volume, ranging from 0.9548 to 0.9604; The difference in the correlations obtained with volume and with area was statistically significant at the 95% level of confidence. Studies using NTL data may be strengthened by consideration of the volume rather than just area of urbanized land.

Title Multispectral analysis of the night sky brightness and its origin for the Asiago Observatory, Italy Type Journal Article
Year (down) 2020 Publication Monthly Notices of the Royal Astronomical Society Abbreviated Journal MNRAS
Volume 491 Issue 3 Pages 4398-4405
Keywords Skyglow; light pollution; numerical methods; Site testing; Italy; Observatories
Abstract Night protection has been a major concern for astronomers since the electrification of cities and is beginning to be recognized as a major environmental problem. In recent years, regulations have been put in place through the establishment of Dark Sky Reserves that impose stringent constraints on lighting practices for cities in protected areas. Astronomers from the Asiago Observatory, located in the Veneto region of Italy, would like to create an area of this nature around their facilities to improve and protect the quality of their astronomical observations. This study assesses the current state of the sky in the region through numerical modelling using the latest improvements to the ILLUMINA model and aims to identify the main contributing sources of artificial light. The explicit calculation of the contribution of private residential lighting helps to discern the origin of the light. We also present a new approach for extracting an estimate of the distribution of lamp technology in a region from images taken from the International Space Station.

Abstract Light pollution and exposure to artificial light at night (ALAN) have become almost universal in the modern world. Although there is an ongoing debate about how such environmental changes can affect human well-being and health, there is no doubt that ALAN perturbs the circadian clock – an ancestral system which synchronizes bodily physiology with the day-night cycle. The eye, especially the retina, has a dual role in this story – on the one hand, it is the unique source of light entry to the central clock in the brain, and on the other, eyes themselves are strongly regulated by endogenous circadian clocks. This editorial gives a very brief overview of the situation and poses certain unanswered questions.

Title Emission spectra of light-pollution sources determined from the light-scattering spectrometry of the night sky Type Journal Article
Year (down) 2020 Publication Monthly Notices of the Royal Astronomical Society Abbreviated Journal
Volume 491 Issue 4 Pages 5586-5594
Keywords Skyglow; Remote Sensing
Abstract The emission spectrum of a light-pollution source is a determining factor for modelling artificial light at night. The spectral composition of skyglow is normally derived from the initial spectra of all artificial light sources contributing to the diffuse illumination of an observation point. However, light scattering in the ambient atmosphere imposes a wavelength-specific distortion on the optical signals captured by the measuring device. The nature of the emission, the spectra and the light-scattering phenomena not only control the spectral properties of the ground-reaching radiation, but also provide a unique tool for remote diagnosis and even identification of the emission spectra of the light-polluting sources. This is because the information contained in the night-sky brightness is preferably measured in directions towards a glowing dome of light over the artificial source of light. We have developed a new method for obtaining the emission spectra using remote terrestrial sensing of the bright patches of sky associated with a source. Field experiments conducted in Vienna and Bratislava have been used to validate the theoretical model and the retrieval method. These experiments demonstrate that the numerical inversion is successful even if the signal-to-noise ratio is small. The method for decoding the emission spectra by the light-scattering spectrometry of a night sky is a unique approach that enables for (i) a systematic characterization of the light-pollution sources over a specific territory, and (ii) a significant improvement in the numerical prediction of skyglow changes that we can expect at observatories.
