Light pollution is the consequence of elevated lighting emitted by human-made artefacts to
the lower atmosphere. Recently, there have been major advances in the assessment and …

The growing emissions of artificial light to the atmosphere are producing, among other
effects, a significant increase of the night sky brightness (NSB) above its expected natural …

In this paper, we present the implementation of a monitoring network for artificial light at
night (ALAN), based on Sky Quality Meter devices (SQM) installed in seven locations of the …

Under stable atmospheric conditions the brightness of the urban sky varies throughout the
night following the time course of the anthropogenic emissions of light. Different types of …

We develop a general optical model and describe the absolute radiometric calibration of the
readings provided by two widely-used night sky brightness sensors based on irradiance-to …

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 light …

Light pollution is a worldwide phenomenon whose consequences for the natural
environment and the human health are being intensively studied nowadays. Most published …

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 …

The COVID-19 epidemic lockdown has a direct influence on urban socioeconomic activity,
including night-time light (NTL) changes. Night-time skyglow, a form of light pollution caused …

To determine the level of light pollution due to human activities, we performed sky-
brightness measurements at Bosscha Observatory, Indonesia (107° 36′ E; 6° 49′ S, 1300 …
