A community standard for recording skyglow data [PDF]
Astronomy & 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.

A linear systems approach to protect the night sky: implications for current and future regulations [PDF]
Royal Society Open Science, 2020 The persistent increase of artificial light emissions is causing a progressive brightening of the night sky in most regions of the world. This process is a threat for the long-term sustainability of the scientific and educational activity of ground-based

Casting a light on the shoreline: The influence of light pollution on intertidal settings
Frontiers in Ecology and Evolution, 2022 Light pollution is becoming prevalent among other coastal stressors, particularly along intertidal habitats, arguably the most exposed to anthropogenic light sources.

Real-World Urban Light Emission Functions and Quantitative Comparison with Spacecraft Measurements
Remote Sensing, 2023 We provide quantitative results from GIS-based modelling of urban emission functions for a range of representative low- and mid-rise locations, ranging from individual streets to residential communities within cities, as well as entire towns and city ...

Methods for Assessment and Monitoring of Light Pollution around Ecologically Sensitive Sites
Journal of Imaging, 2019 Since the introduction of electric lighting over a century ago, and particularly in the decades following the Second World War, indications of artificial light on the nighttime Earth as seen from Earth orbit have increased at a rate exceeding that of ...

Night-time monitoring of the aerosol content of the lower atmosphere by differential photometry of the anthropogenic skyglow [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2020 ABSTRACT Night-time 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 anthropogenic night-sky brightness due to city lights can be successfully used for estimating the aerosol optical depth of arbitrarily thick ...

Research on the Lighting Performance of LED Street Lights With Different Color Temperatures
IEEE Photonics Journal, 2015 While light-emitting diodes (LEDs) are a very efficient lighting option, whether phosphor-coated LEDs (PC-LEDs) are suitable for street lighting remains to be tested.

Skyglow extends into the world's Key Biodiversity Areas
Animal Conservation, 2019 AbstractThe proportion of the Earth's surface that experiences a naturally dark environment at night is rapidly declining with the introduction of artificial light. Biological impacts of this change have been documented from genes to ecosystems, and for a wide diversity of environments and organisms. The likely severity of these impacts depends heavily
