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.
