Title NixNox procedure to build Night Sky Brightness maps from SQM photometers observations Type Report
Year 2014 Publication E-prints Complutense Abbreviated Journal
Volume Issue 26982 Pages
Keywords Skyglow; measurement; SQM; SQM-L; mapping
Abstract The NixNox procedure to build all-sky maps of the nocturnal night sky brightness using SQM photometers is described. Astronomers belonging to amateur associations in Spain are using this observational method to obtain data of their preferred sites of observation to characterize the astronomical quality of the sky and the sources of light pollution.

Title Naked-eye star visibility and limiting magnitude mapped from DMSP-OLS satellite data Type Journal Article
Year 2001 Publication Monthly Notices of the Royal Astronomical Society Abbreviated Journal Monthly Notices of the Royal Astronomical Society
Volume 323 Issue 1 Pages 34-46
Keywords light at night; remote sensing; GTOPO30; DMSP; light pollution; modeling; mapping
Abstract We extend the method introduced by Cinzano et al. (2000a) to map the artificial sky brightness in large territories from DMSP satellite data, in order to map the naked eye star visibility and telescopic limiting magnitudes. For these purposes we take into account the altitude of each land area from GTOPO30 world elevation data, the natural sky brightness in the chosen sky direction, based on Garstang modelling, the eye capability with naked eye or a telescope, based on the Schaefer (1990) and Garstang (2000b) approach, and the stellar extinction in the visual photometric band. For near zenith sky directions we also take into account screening by terrain elevation. Maps of naked eye star visibility and telescopic limiting magnitudes are useful to quantify the capability of the population to perceive our Universe, to evaluate the future evolution, to make cross correlations with statistical parameters and to recognize areas where astronomical observations or popularisation can still acceptably be made. We present, as an application, maps of naked eye star visibility and total sky brightness in V band in Europe at the zenith with a resolution of approximately 1 km.

Title Mapping regional economic activity from night-time light satellite imagery Type Journal Article
Year 2006 Publication Ecological Economics Abbreviated Journal Ecological Economics
Volume 57 Issue 1 Pages 75-92
Keywords Night-time light satellite imagery; Economic activity; Geographic information; Mapping; Scale
Abstract The recognition that the elements of the ‘anthropocene’ play a critical role in global change processes means that datasets describing elements of the socio-economic environment are becoming increasingly more desirable. The ability to present these data in a gridded format as opposed to the traditionally reported administrative units is advantageous for incorporation with other environmental datasets. Night-time light remote sensing data has been shown to correlate with national-level figures of Gross Domestic Product (GDP). Night-time radiance data is analysed here along with regional economic productivity data for 11 European Union countries along with the United States at a number of sub-national levels. Night-time light imagery was found to correlate with Gross Regional Product (GRP) across a range of spatial scales. Maps of economic activity at 5 km resolution were produced based on the derived relationships. To produce these maps, certain areas had to be excluded due to their anomalously high levels of economic activity for the amount of total radiance present. These areas were treated separately from other areas in the map. These results provide the first detailed examination of night-time light characteristics with respect to local economic activity and highlight issues, which should be considered when undertaking such analysis.

Title Light as a modulator of cognitive brain function Type Journal Article
Year 2009 Publication Trends in Cognitive Sciences Abbreviated Journal Trends Cogn Sci
Volume 13 Issue 10 Pages 429-438
Keywords Human Health; Animals; Brain/anatomy & histology/*physiology; Brain Mapping; Circadian Rhythm/*physiology; Cognition/*physiology; Diagnostic Imaging/methods; Humans; *Light; Melatonin/metabolism; Retina/anatomy & histology/physiology; Visual Pathways/anatomy & histology/physiology
Abstract Humans are a diurnal species usually exposed to light while engaged in cognitive tasks. Light not only guides performance on these tasks through vision but also exerts non-visual effects that are mediated in part by recently discovered retinal ganglion cells maximally sensitive to blue light. We review recent neuroimaging studies which demonstrate that the wavelength, duration and intensity of light exposure modulate brain responses to (non-visual) cognitive tasks. These responses to light are initially observed in alertness-related subcortical structures (hypothalamus, brainstem, thalamus) and limbic areas (amygdala and hippocampus), followed by modulations of activity in cortical areas, which can ultimately affect behaviour. Light emerges as an important modulator of brain function and cognition.
