  Title 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.

  Title 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 An All-Sky Transmission Monitor: ASTMON Type Journal Article
  Year 2011 Publication Publications of the Astronomical Society of the Pacific Abbreviated Journal Publications of the Astronomical Society of the Pacific  
  Volume 123 Issue 907 Pages 1076-1086  
  Keywords monitoring; light at night; light pollution; skyglow  
  Abstract We present here the All-Sky Transmission Monitor (ASTMON), designed to perform a continuous monitoring of the surface brightness of the complete night sky in several bands. The data acquired are used to derive, in addition, a subsequent map of the multiband atmospheric extinction at any location in the sky and a map of the cloud coverage. The instrument has been manufactured to withstand extreme weather conditions and to remain operative. Designed to be fully robotic, it is ideal to be installed outdoors as a permanent monitoring station. The preliminary results based on two of the currently operative units (at Doñana National Park, Huelva, and at the Calar Alto Observatory, Almería, Spain) are presented here. The parameters derived using ASTMON are in good agreement with those previously reported, which illustrates the validity of the design and the accuracy of the manufacturing. The information provided by this instrument will be presented in forthcoming articles, once we have accumulated a statistically significant amount of data.

  Title From The Ground Up I: Light Pollution Sources in Flagstaff, Arizona Type Journal Article
  Year 2009 Publication Publications of the Astronomical Society of the Pacific Abbreviated Journal Publ Astron Soc Pac  
  Volume 121 Issue 876 Pages 185-203  
  Keywords light pollution; Flagstaff; Arizona; measurements; lighting policy; public policy  
  Abstract We develop an estimate of the complete outdoor lighting of Flagstaff Arizona, as well as lighting-use densities (lumens per acre) for a number of different land uses. We find a total outdoor light output of 173 million lumens (Mlm) including sports lighting, and 139 Mlm without sports lighting, with an uncertainty of about 7%. The average fraction escaping directly upward from light fixtures is estimated to be 8.3%. After correcting approximately for near-ground blocking described in the accompanying paper by Luginbuhl et al., total uplight is estimated at 17.9 Mlm or 12.2 Mlm with and without sports lighting, respectively. Of these 17.9 Mlm, 33% arise from sports lighting, when it is on; when sports lighting is off, commercial and industrial lighting account for 62% with the remainder dominated by residential (14%) and roadway lighting (12%). We show that the 1989 Flagstaff lighting code that limited total outdoor lighting on new construction has reduced the growth rate of lighting, resulting in a 17% growth in light escaping into the sky from 1989 to 2003, compared to a 43% increase expected if the 1989 code had not been enacted. If all legally nonconforming lighting installed before 1989 were to be brought into compliance with the code, we would expect sky glow in Flagstaff to actually decrease by 36% compared to that in 2003; if all lighting, including residential, could be converted to fully shielded fixtures, sky glow would decrease to about half the current value. The implications for the most effective ways to address sky glow through lighting codes are discussed.

  Title Light Pollution At High Zenith Angles, As Measured at Cerro Tololo Inter-American Observatory1 Type Journal Article
  Year 2010 Publication Publications of the Astronomical Society of the Pacific Abbreviated Journal Publ Astron Soc Pac  
  Volume 122 Issue 889 Pages 373-377  
  Keywords Astronomical Phenomena and Seeing; Cerro Tololo; Garstang model; skyglow; light pollution; measurements  
  Abstract On the basis of measurements of the V-band sky brightness obtained at Cerro Tololo Inter-American Observatory in 2006 December and 2008 December we confirm the functional form of the basic model of Garstang. At high zenith angles we measure an enhancement of a factor of 2 over Garstang’s later model when there is no marine cloud layer over La Serena/Coquimbo. No corresponding enhancement is found in the B band.
