  Title (up) 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.

  Title (up) Measuring Night-Sky Brightness with a Wide-Field CCD Camera Type Journal Article
  Year 2007 Publication Publications of the Astronomical Society of the Pacific Abbreviated Journal Publ Astron Soc Pac  
  Volume 119 Issue 852 Pages 192-213  
  Keywords light pollution; light at night; skyglow; monitoring; measurement; CCD  
  Abstract We describe a system for rapidly measuring the brightness of the night sky using a mosaic of CCD images obtained with a low-cost automated system. The portable system produces millions of independent photometric measurements covering the entire sky, enabling the detailed characterization of natural sky conditions and light domes produced by cities. The measurements are calibrated using images of standard stars contained within the raw data, producing results closely tracking the Johnson V astronomical standard. The National Park Service has collected hundreds of data sets at numerous parks since 2001 and is using these data for the protection and monitoring of the night-sky visual resource. This system also allows comprehensive characterization of sky conditions at astronomical observatories. We explore photometric issues raised by the broadband measurement of the complex and variable night-sky spectrum, and potential indices of night-sky quality.

  Title (up) Sky Brightness at Weihai Observatory of Shandong University Type Journal Article
  Year 2014 Publication Publications of the Astronomical Society of the Pacific Abbreviated Journal Publications of the Astronomical Society of the Pacific  
  Volume 126 Issue 939 Pages 496-503  
  Keywords  
  Abstract In this paper, a total of about 28000 images in V and R band obtained on 161 nights using the one-meter optical telescope at Weihai Observatory (WHO) of Shandong University since 2008 to 2012 have been processed to measure the sky brightness. It provides us with an unprecedented database, which can be used to study the variation of the sky brightness with the sky position, the moonlight contribution, and the twilight sky brightness. The darkest sky brightness is about 19.0 and 18.6 mag arcsec−2 in V and R band, respectively. An obvious darkening trend is found at the first half of the night at WHO, and the variation rate is much larger in summer than that in other seasons. The sky brightness variation depends more on the azimuth than on the altitude of the telescope pointing for WHO. Our results indicate that the sky brightness at WHO is seriously influenced by the urban light.

  Title (up) Sky glow and outdoor lighting trends since 1976 at the Lowell Observatory Type Journal Article
  Year 1990 Publication Publications of the Astronomical Society of the Pacific Abbreviated Journal PASP  
  Volume 102 Issue Pages 481  
  Keywords Skyglow; Lighting  
  Abstract Urban sky-glow (light pollution) trends, recorded photoelectrically in intermediate-band b (472 nm) and y (551 nm) filters at the original site of the Lowell Observatory on Mars Hill near downtown Flagstaff, Arizona, reflect not just the population growth of the surrounding city but also some ameliorating effects of lighting controls and a changing mix of outdoor lighting sources. Since 1976 the sky brightness increased in b but has been virtually constant in y. New ordinances limit lighting growth near observatories and require monochromatic low-pressure sodium luminaires for most applications.
