Imaging and mapping the impact of clouds on skyglow with all-sky photometry [PDF]

open access: yesScientific Reports, 2017
Artificial skyglow is constantly growing on a global scale, with potential ecological consequences ranging up to affecting biodiversity. To understand these consequences, worldwide mapping of skyglow for all weather conditions is urgently required.

Let there be Skyglow—light pollution from a large outdoor music festival (Lollapalooza Berlin 2016) [PDF]

open access: yesScientific Reports
Live music is often linked to elaborate light shows, particularly at large outdoor music festivals. However, artificial light at night is one form of environmental pollution, light pollution, and because outdoor festivals emit a substantial amount of ...

Design and implementation of an illumination system to mimic skyglow at ecosystem level in a large-scale lake enclosure facility [PDF]

open access: yesScientific Reports, 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.

Skyglow-Induced Luminance Gradients Influence Orientation in a Migratory Moth [PDF]

open access: yesInsects
Artificial light at night (ALAN) is altering nocturnal ecosystems. While the effects of direct light sources on insect behavior are well studied, the influence of large-scale skyglow on migratory orientation remains unclear.

Experimental study on the impact of continuous and dynamic artificial light at night on moths originating from different skyglow conditions [PDF]

open access: yesScientific Reports
Biodiversity is negatively affected by light pollution, caused by artificial light at night (ALAN). Light-emitting diodes facilitate new lighting technologies to mediate the negative effects of ALAN, such as dynamic ALAN where light intensity can be ...

Artificial light at night is a top predictor of bird migration stopover density [PDF]

open access: yesNature Communications, 2023
As billions of nocturnal avian migrants traverse North America, twice a year they must contend with landscape changes driven by natural and anthropogenic forces, including the rapid growth of the artificial glow of the night sky.

Verification of Angular Response of Sky Quality Meter with Quasi-Punctual Light Sources [PDF]

open access: yesSensors, 2021
Sky Quality Meter (SQM) is a commercial instrument based on photometers widely used by amateur astronomers for skyglow measurement from the ground. In the framework of the MINLU project, two SQM-LE units were integrated in an autonomous sensor suite ...

Air pollution mitigation can reduce the brightness of the night sky in and near cities [PDF]

open access: yesScientific Reports, 2021
Light pollution is a novel environmental problem whose extent and severity are rapidly increasing. Among other concerns, it threatens global biodiversity, nocturnal animal migration, and the integrity of the ground-based astronomy research enterprise ...

SG-WAS: A New Wireless Autonomous Night Sky Brightness Sensor [PDF]

open access: yesSensors, 2021
The main features of SG-WAS (SkyGlow Wireless Autonomous Sensor), a low-cost device for measuring Night Sky Brightness (NSB), are presented. SG-WAS is based on the TSL237 sensor –like the Unihedron Sky Quality Meter (SQM) or the STARS4ALL Telescope ...
