RGB photometric calibration of 15 million Gaia stars
Nicolás Cardiel, Jaime Zamorano, Josep Manel Carrasco +6
Although a catalogue of synthetic RGB magnitudes, providing photometric data for a sample of 1346 bright stars, has been recently published, its usefulness is still limited due to…
Keeping light pollution at bay: a red-lines, target values, top-down approach
Salvador Bará, Fabio Falchi, Raul C. Lima +1
The prevailing regulatory framework for light pollution control is based on establishing conditions on individual light sources or single installations (regarding features like ULO…
Synthetic RGB photometry of bright stars: definition of the standard photometric system and UCM library of spectrophotometric spectra
Nicolás Cardiel, Jaime Zamorano, Salvador Bará +10
Although the use of RGB photometry has exploded in the last decades due to the advent of high-quality and inexpensive digital cameras equipped with Bayer-like color filter systems,…
A multi-band map of the natural night sky brightness including Gaia and Hipparcos integrated starlight
Eduard Masana, Josep Manel Carrasco, Salvador Bará +1
The natural night sky brightness is a relevant input for monitoring the light pollution evolution at observatory sites, by subtracting it from the overall sky brightness determined…
Nighttime monitoring of the aerosol content of the lower atmosphere by differential photometry of the anthropogenic skyglow
Miroslav Kocifaj, Salvador Bará
Nighttime monitoring of the aerosol content of the lower atmosphere is a challenging task, because appropriate reference natural light sources are lacking. Here we show that the an…
Direct assessment of the sensitivity drift of SQM sensors installed outdoors
Salvador Bará, Enric Marco, Salvador J. Ribas +3
Long-term monitoring of the evolution of the artificial night sky brightness is a key tool for developing science-informed public policies and assessing the efficacy of light pollu…
Protecting the night sky darkness in astronomical observatories: a linear systems approach
Fabio Falchi, Salvador Bará
The sustained increase of emissions of artificial light is causing a progressive brightening of the night sky in most of the world. This process represents a threat for the long-te…
Aerosol characterization using satellite remote sensing of light pollution sources at night
Miroslav Kocifaj, Salvador Bará
A demanding challenge in atmospheric research is the night-time characterization of aerosols using passive techniques, that is, by extracting information from scattered light that…
Magnitude to luminance conversions and visual brightness of the night sky
Salvador Bará, Martin Aubé, John Barentine +1
The visual brightness of the night sky is not a single-valued function of its brightness in other photometric bands, because the transformations between photometric systems depend…
Two-index model for characterizing site-specific night sky brightness patterns
Miroslav Kocifaj, Salvador Bará
Determining the all-sky radiance distribution produced by artificial light sources is a computationally demanding task that generally requires an intensive calculation load. We dev…
Monitoring transition: expected night sky brightness trends in different photometric bands
Salvador Bará, Iago Rigueiro, Raul C. Lima
Several light pollution indicators are commonly used to monitor the effects of the transition from outdoor lighting systems based on traditional gas-discharge lamps to solid-state…
Fast Fourier-transform calculation of artificial night sky brightness maps
Salvador Bará, Fabio Falchi, Riccardo Furgoni +1
Light pollution poses a growing threat to optical astronomy, in addition to its detrimental impacts on the natural environment, the intangible heritage of humankind related to the…
Photons without borders: quantifying light pollution transfer between territories
Salvador Bará, Raul C. Lima
The light pollution levels experienced at any given site generally depend on a wide number of artificial light sources distributed throughout the surrounding territory. Since photo…
Light pollution in shallow coastal waters: aquaculture farming in the Galician Atlantic shoreline
Salvador Bará, M. Luz Pérez-Parallé, José L. Sánchez +3
Artificial light at night is a relevant environmental stressor whose unwanted consequences have been documented by a growing body of research. In this work we analize the loss of t…
Variations on a classical theme: On the formal relationship between magnitudes per square arcsecond and luminance
Salvador Bará
The formal link between magnitudes per square arcsecond and luminance is discussed in this paper. Directly related to the human visual system, luminance is defined in terms of the…
Characterizing the zenithal night sky brightness in large territories: How many samples per square kilometer are needed?
Salvador Bará
A recurring question arises when trying to characterize, by means of measurements or theoretical calculations, the zenithal night sky brightness throughout a large territory: how m…
Light pollution offshore: zenithal sky glow measurements in the Mediterranean coastal waters
Xavier Ges, Salvador Bará, Manuel García-Gil +3
Light pollution is a worldwide phenomenon whose consequences for the natural environment and the human health are being intensively studied nowadays. Most published studies address…
On lamps, walls, and eyes: the spectral radiance field and the evaluation of light pollution indoors
Salvador Bará, Jaume Escofet
Light plays a key role in the regulation of different physiological processes, through several visual and non-visual retinal phototransduction channels whose basic features are bei…
