Using all-sky differential photometry to investigate how nocturnal clouds darken the night sky in rural areas. [PDF]

open access: yesSci Rep, 2019
Artificial light at night has affected most of the natural nocturnal landscapes worldwide and the subsequent light pollution has diverse effects on flora, fauna and human well-being. To evaluate the environmental impacts of light pollution, it is crucial

Skyglow facilitates prey detection in a crepuscular insectivore: distant light sources create bright skies.

open access: yesEnvironmental Pollution
Light profoundly shapes ecosystems, influencing the behaviour and niche specialisation of many species. This is especially true for visual predators, particularly crepuscular and nocturnal animals, whose foraging depends on adequate illumination. Despite

A community standard for recording skyglow data [PDF]

open access: yesAstronomy & Geophysics, 2012
Christopher Kyba and Dorien Lolkema describe a standard format for recording skyglow data developed by the light at night research community, with the goal of improving data exchange between researchers.

Mimicking skyglow at ecosystem level in a large-scale lake enclosure facility

open access: yes, 2021
Light pollution is an environmental stressor of global extent that is growing exponentially in area and intensity. Artificial skyglow, a form of light pollution with large range, is hypothesized to have environmental impact at ecosystem level. However,

Tracking the dynamics of skyglow with differential photometry using a digital camera with fisheye lens [PDF]

open access: yesJournal of Quantitative Spectroscopy and Radiative Transfer, 2018
Artificial skyglow is dynamic due to changing atmospheric conditions and the switching on and off of artificial lights throughout the night. Street lights as well as the ornamental illumination of historical sites and buildings are sometimes switched off

On the feasibility of using ceilometer backscatter profile as input data for skyglow simulation

open access: yesJournal of Quantitative Spectroscopy and Radiative Transfer, 2020
Atmospheric conditions can significantly affect the sky brightness originating from artificial lights. Previous works studied the cloudiness, cloud base height, optical depth of cloud, aerosol optical depth and aerosol scale height as atmospheric ...

Angular Emission Function of a City and Skyglow Modeling: A Critical Perspective

open access: yesPublications of the Astronomical Society of the Pacific, 2016
The radiative transfer equation (RTE) is a common approach to solving the transfer of electromagnetic energy in heterogeneous disperse media, such as atmospheric environment. One-dimensional RTE is a linear boundary value problem that is well suited to plane-parallel atmosphere with no diffuse intensity entering the top of the atmosphere.
