Title Measuring the Night Sky Brightness with the Lightmeter. Type Journal Article
Year 2011 Publication ReVMexAA Abbreviated Journal
Volume 41 Issue Pages 46–49
Keywords Instrumentation; instrumentation: photometers; light pollution; methods: data analysis; methods: observational; site testing
Abstract We present a newly developed, low-cost photometer for long-term monitoring of the night sky brightness and

light pollution on Earth. The so-called Lightmeter is an as far as possible stand-alone operational, fully

weatherproof, and maintenance-free device. It provides a high data sampling rate of up to 1 Hz as well as a

superb sensitivity covering the whole brightness range down to the darkest night time conditions. The excellent

performance of the Lightmeter allows a continuously monitoring of the night sky brightness and opens a wide

range of applications at an observatory site like determining overall sky conditions in real time, cloud detection

and estimation of their velocity, measuring relative changes in extinction as well as the detection of long term

trends in brightness caused by an increase of artificial illumination. We will present first results of measurements

taken at Cerro Armazones, one of the best obser

Title Night Sky Photometry with Sky Quality Meter Type Journal Article
Year 2005 Publication Technical Report 9, ISTIL. V1.4. Abbreviated Journal
Volume Issue Pages
Keywords Instrumentation; light pollution; night sky brightness; photometry; instruments; calibration
Abstract Sky Quality Meter, a low cost and pocket size night sky brightness photometer, opens to the general public the possibility to quantify the quality of the night sky. Expecting a large diffusion of measurements taken with this instrument, I tested and characterized it. I analyzed with synthetic photometry and laboratory measurements the relationship between the SQM photometrical system and the main systems used in light pollution studies. I evaluated the conversion factors to Johnson’s B and V bands, CIE photopic and CIE scotopic responses for typical spectra and the spectral mismatch correction factors when specific filters are added.

Title Street lighting changes the composition of invertebrate communities Type Journal Article
Year 2012 Publication Biology Letters Abbreviated Journal
Volume 8 Issue 5 Pages 764-767
Keywords Ecology; artificial light pollution; community composition; ground-dwelling invertebrates; high pressure sodium; street lights
Abstract Artificial lighting has been used to illuminate the nocturnal environment for centuries and continues to expand with urbanization and economic development. Yet, the potential ecological impact of the resultant light pollution has only recently emerged as a major cause for concern. While investigations have demonstrated that artificial lighting can influence organism behaviour, reproductive success and survivorship, none have addressed whether it is altering the composition of communities. We show, for the first time, that invertebrate community composition is affected by proximity to street lighting independently of the time of day. Five major invertebrate groups contributed to compositional differences, resulting in an increase in the number of predatory and scavenging individuals in brightly lit communities. Our results indicate that street lighting changes the environment at higher levels of biological organization than previously recognized, raising the potential that it can alter the structure and function of ecosystems.

Title The Dark Side of Light: A Transdisciplinary Research Agenda for Light Pollution Policy Type Journal Article
Year 2010 Publication Ecol Soc Abbreviated Journal
Volume 15 Issue 4 Pages
Keywords Ecology; artificial light; energy efficiency; lighting concept; light pollution; nightscape; policy; sustainability; transdisciplinary
Abstract Although the invention and widespread use of artificial light is clearly one of the most important human technological advances, the transformation of nightscapes is increasingly recognized as having adverse effects. Night lighting may have serious physiological consequences for humans, ecological and evolutionary implications for animal and plant populations, and may reshape entire ecosystems. However, knowledge on the adverse effects of light pollution is vague. In response to climate change and energy shortages, many countries, regions, and communities are developing new lighting programs and concepts with a strong focus on energy efficiency and greenhouse gas emissions. Given the dramatic increase in artificial light at night (0 – 20% per year, depending on geographic region), we see an urgent need for light pollution policies that go beyond energy efficiency to include human well-being, the structure and functioning of ecosystems, and inter-related socioeconomic consequences. Such a policy shift will require a sound transdisciplinary understanding of the significance of the night, and its loss, for humans and the natural systems upon which we depend. Knowledge is also urgently needed on suitable lighting technologies and concepts which are ecologically, socially, and economically sustainable. Unless managing darkness becomes an integral part of future conservation and lighting policies, modern society may run into a global self-experiment with unpredictable outcomes.
