Atmospheric Light Pollution by Proposed Reflect Orbital Space Mirrors
Miroslav Kocifaj, Gáspár Bakos, František Kundracik
ReflectOrbital is planning to launch a \,m mirror in space at a 600\,km altitude to illuminate a \,km radius circular patch on Earth. The pilot satellite, ca…
Aerosol parameters for night sky brightness modelling estimated from daytime sky images
Miroslav Kocifaj, František Kundracik, John Barentine
Atmospheric turbidity is one of the key factors influencing the propagation of artificial light into the environment during cloudless nights. High aerosol loading can reduce the vi…
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…
Modelling the artificial night sky brightness at short distances from streetlights
Salvador Bará, Carmen Bao-Varela, Miroslav Kocifaj
Contrary to some widespread intuitive belief, the night sky brightness perceived by the human eye or any other physical detector does not come (exclusively) from high in the sky. T…
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…
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…
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…
Recovering the city street lighting fraction from skyglow measurements in a large-scale municipal dimming experiment
John C. Barentine, František Kundracik, Miroslav Kocifaj +7
Anthropogenic skyglow dominates views of the natural night sky in most urban settings, and the associated emission of artificial light at night (ALAN) into the environment of citie…
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…
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…
Formation of recurring slope lineae on Mars by rarefied gas-triggered granular flows
F. Schmidt, F. Andrieu, F. Costard +2
Active dark flows known as recurring slope lineae have been observed on the warmest slopes of equatorial Mars. The morphology, composition and seasonality of the lineae suggest a r…
Skyglow Changes Over Tucson, Arizona, Resulting From A Municipal LED Street Lighting Conversion
John C. Barentine, Constance E. Walker, Miroslav Kocifaj +4
The transition from earlier lighting technologies to white light-emitting diodes (LEDs) is a significant change in the use of artificial light at night. LEDs emit considerably more…
Sky Quality Meter measurements in a colour changing world
A. Sánchez de Miguel, M. Aubé J. Zamorano, M. Kocifaj +2
The Sky Quality Meter (SQM) has become the most common device to track the evolution of the brightness of the sky from polluted regions to first class astronomical observatories. A…
An Insolation Activated Dust Layer on Mars
Caroline de Beule, Gerhard Wurm, Thorben Kelling +2
The illuminated dusty surface of Mars acts like a gas pump. It is driven by thermal creep at low pressure within the soil. In the top soil layer this gas flow has to be sustained b…
Tables of phase functions, opacities, albedos, equilibrium temperatures, and radiative accelerations of dust grains in exoplanets
Jan Budaj, Miroslav Kocifaj, Raquel Salmeron +1
There has been growing observational evidence for the presence of condensates in the atmospheres and/or comet-like tails of extrasolar planets. As a result, systematic and homogene…
Dust Ejection from Planetary Bodies by Temperature Gradients: Laboratory Experiments
Thorben Kelling, Gerhard Wurm, Miroslav Kocifaj +2
Laboratory experiments show that dusty bodies in a gaseous environment eject dust particles if they are illuminated. We find that even more intense dust eruptions occur when the li…
Real Dust Particles and Unimportance of the Poynting-Robertson Effect
M. Kocifaj, J. Klacka
The importance of the Poynting-Robertson effect on the motion of interplanetary dust particles is discussed. Precise numerical calculations for real dust particle show that conditi…
