Trust, but verify: Reducing artificial light emissions and monitoring compliance
Salvador Bará
In order to reduce light pollution we have to reduce the overall amount of artificial light emissions. This is a consequence of the basic rules governing the propagation of light i…
Diverging evolution of light pollution indicators: can the Globe at Night and VIIRS-DNB measurements be reconciled?
Salvador Bará, José J. Castro-Torres
The radiance of nighttime artificial lights measured by the VIIRS-DNB instrument on board the satellite Suomi-NPP increases at an average rate ~2.2 %/yr worldwide, whereas the arti…
Detecting changes in anthropogenic light emissions: limits due to atmospheric variability
Salvador Bará
Monitoring the evolution of the anthropogenic light emissions is a priority task in light pollution research. Among the complementary approaches that can be adopted to achieve this…
Quantifying the visual impact of wind farm lights on the nocturnal landscape
Salvador Bará, Raul C. Lima
Wind farm lights are a conspicuous feature in the nocturnal landscape. Their presence is a source of light pollution for residents and the environment, severely disrupting in some…
Aggregate Effects of Proliferating LEO Objects and Implications for Astronomical Data Lost in the Noise
John C. Barentine, Aparna Venkatesan, Jessica Heim +3
The rising population of artificial satellites and associated debris in low-altitude orbits is increasing the overall brightness of the night sky, threatening ground-based astronom…
Skyglow inside your eyes: intraocular scattering and artificial brightness of the night sky
Salvador Bará, Carmen Bao-Varela
The visual perception of the natural night sky in many places of the world is strongly disturbed by anthropogenic light. Part of this artificial light is scattered in the atmospher…
Quantitative evaluation of outdoor artificial light emissions using low Earth orbit radiometers
Salvador Bará, Carmen Bao-Varela, Raul C. Lima
Low Earth orbit radiometers allow monitoring nighttime anthropogenic light emissions in wide areas of the planet. In this work we describe a simple model for assessing significant…
Towards a global map of the artificial all-sky brightness
Miroslav Kocifaj, Salvador Bará, Fabio Falchi
Modeling the hemispherical night sky brightness of anthropogenic origin is a demanding computational challenge, due to the intensive calculations required to produce all-sky maps w…
Estimating linear radiance indicators from the zenith night sky brightness: on the Posch ratio for natural and light polluted skies
Salvador Bará, Xabier Pérez-Couto, Fabio Falchi +2
Estimating the horizontal irradiance from measurements of the zenith night sky radiance is a useful operation for basic and applied studies in observatory site assessment, atmosphe…
Can we illuminate our cities and (still) see the stars?
Salvador Bará, Fabio Falchi, Raul C. Lima +1
Could we enjoy starry skies in our cities again? Arguably yes. The actual number of visible stars will depend, among other factors, on the spatial density of the overall city light…
The proliferation of space objects is a rapidly increasing source of artificial night sky brightness
Miroslav Kocifaj, Frantisek Kundracik, John C. Barentine +1
The population of artificial satellites and space debris orbiting the Earth imposes non-negligible constraints on both space operations and ground-based optical and radio astronomy…
