Guide Optical remote measurement techniques are most typically designed and used to measure concentrations and, when paired with meteorological data, allow calculation of mass fluxes of
Guide Personal digital devices, emitting high-energy light, namely in the blue wavelength, have raised concerns about possible harmful effects on users'' eyes. Scientific research history has shown
Guide Recently, there have been major advances in the assessment and mitigation of light pollution impacts on humans and the natural ecosystems. Severe negative impacts of light pollution
Guide Understanding the causes and potential mitigations of light pollution requires measuring and monitoring artificial light at night (ALAN). We review how
Guide Artificial skyglow is the form of light pollution impacting ground-based observatories. Many of the professional observatories with 4-m class telescopes were built decades ago in proximity
Guide Artificial light at night (ALAN) is ever-present in modern society and has revolutionised our lives. Along with its many benefits, ALAN can have adverse effects that are studied across many
Guide Consequently, various forms of pollution, including air pollution, noise pollution, water pollution, and more recently, light pollution, have emerged as critical sources of concern, impacting climate
Guide Light pollution has increased globally, with 80% of the total population now living under light-polluted skies. In this Review, we elucidate the scope and importance of light pollution and...
Guide Light with a high energy density can cause irreversible damage to the light-sensitive photoreceptors. In this blog article, we take a look at the effects on
Guide Personal digital devices, emitting high-energy light, namely in the blue wavelength, have raised concerns about possible harmful effects on users'' eyes.
Guide Reports have also argued that certain types of air pollution such as smoke, can further exacerbate light pollution because it can cause light to scatter in different directions, brightening “night” skies further (3).
Guide In a descriptive sense, light pollution occurs when artificial light is used in a poor or excessive way, especially at night, causing negative effects in the environment and the view of the night sky.
Guide According to DarkSky International, an organisation that advocates for limits on light pollution, one-third of all light in developed countries is wasted by poorly directed or unshielded lamps.
Guide Understanding the causes and potential mitigations of light pollution requires measuring and monitoring artificial light at night (ALAN). We review how ALAN is measured, both from the
