Title Detection of rural electrification in Africa using DMSP-OLS night lights imagery Type Journal Article
Year 2013 Publication International Journal of Remote Sensing Abbreviated Journal International Journal of Remote Sensing
Volume 34 Issue 22 Pages 8118-8141
Keywords Remote Sensing
Abstract We report on the first systematic ground-based validation of the US Air Force Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) night lights imagery to detect rural electrification in the developing world. Drawing upon a unique survey of villages in Senegal and Mali, this study compares night-time light output from the DMSP-OLS against ground-based survey data on electricity use in 232 electrified villages and additional administrative data on 899 unelectrified villages. The analysis reveals that electrified villages are consistently brighter than unelectrified villages across annual composites, monthly composites, and a time series of nightly imagery. Electrified villages appear brighter because of the presence of streetlights, and brighter villages tend to have more streetlights. By contrast, the correlation of light output with household electricity use and access is low. We further demonstrate that a detection algorithm using data on night-time light output and the geographic location of settlements can accurately classify electrified villages. This research highlights the potential to use night lights imagery for the planning and monitoring of ongoing efforts to connect the 1.4 billion people who lack electricity around the world.

Title Advances in Remote Sensing: Imaging the Earth by Moonlight Type Journal Article
Year 2013 Publication Eos, Transactions American Geophysical Union Abbreviated Journal Eos Trans. AGU
Volume 94 Issue 40 Pages 349-350
Keywords Remote Sensing; night; visible; VIIRS
Abstract Earth's nighttime environment is being revealed in unprecedented detail by the new satellite-mounted Visible/Infrared Imaging Radiometer Suite (VIIRS). VIIRS' Day/Night Band (DNB) is a highly sensitive broadband visible channel capable of detecting light from cities and other terrestrial emission sources.

Title The impact of watching television on evening melatonin levels: Impact of watching television on evening melatonin Type Journal Article
Year 2013 Publication Journal of the Society for Information Display Abbreviated Journal Jnl Soc Info Display
Volume 21 Issue 10 Pages 417-421
Keywords Human Health; television; correlated color temperature; sleep; melatonin levels; blue light; circadian disruption
Abstract Self-luminous electronic devices emit optical radiation at short wavelengths, close to the peak sensitivity of melatonin suppression. The present paper investigated if light from a 178-cm (70 in.) television suppressed melatonin. Results showed that light from televisions does not impact melatonin levels in the evening.

Title Effect of bedside light on sleep quality and background eeg rhythms Type Journal Article
Year 2013 Publication Sleep Medicine Abbreviated Journal Sleep Medicine
Volume 14 Issue Pages e170
Keywords Human Health
Abstract Artificial lighting has benefited society by extending the length of a productive day, but it can be ”light pollution” when it becomes excessive. Unnecessary exposure to artificial light at night can cause myopia, obesity, metabolic disorders and even some type of cancers.

Title Measuring Anthropogenic Sky Glow Using a Natural Sky Brightness Model. Type Journal Article
Year 2013 Publication Publications of the Astronomical Society of the Pacific Abbreviated Journal
Volume 125 Issue 933 Pages 1370-1382
Keywords Skyglow
Abstract Anthropogenic sky glow (a result of light pollution) combines with the natural background brightness of the night sky when viewed by an observer on the earth’s surface. In order to measure the anthropogenic component accurately, the natural component must be identified and subtracted. A model of the moonless natural sky brightness in the V-band was constructed from existing data on the Zodiacal Light, an airglow model based on the van Rhijn function, and a model of integrated starlight (including diffuse galactic light) constructed from images made with the same equipment used for sky brightness observations. The model also incorporates effective extinction by the atmosphere and is improved at high zenith angles (>80°) by the addition of atmospheric diffuse light. The model may be projected onto local horizon coordinates for a given observation at a resolution of 0.05° over the hemisphere of the sky, allowing it to be accurately registered with data images obtained from any site. Zodiacal Light and integrated starlight models compare favorably with observations from remote dark sky sites, matching within ± 8 nL over 95% of the sky. The natural airglow may be only approximately modeled, errors of up to ± 25 nL are seen when the airglow is rapidly changing or has considerable character (banding); ± 8 nL precision may be expected under favorable conditions. When subtracted from all-sky brightness data images, the model significantly improves estimates of sky glow from anthropogenic sources, especially at sites that experience slight to moderate light pollution.
