  Title A simple propagation law for artificial night-sky illumination Type Journal Article
  Year 1973 Publication The Observatory Abbreviated Journal  
  Volume 93 Issue Pages 117-120  
  Keywords Skyglow  
  Abstract The problem of locating new large astronomical observatories in sites which have a suitably dark night sky (artificial excess of the order of omi) is becoming increasingly difficult in Europe and the United States, on account of extensive urban development, the high luminous efficiency of modern discharge lighting, and the scattering of light in an atmosphere contaminated by aerosols. To investigate the artificial illumination of the sky over large regions on the basis of necessarily limited observations, one needs an expression for the zenith brightness produced by towns of known site and distance.

The exact derivation of such a law is exceedingly complex, involving the computation of the radiation transfer in an atmosphere with absorption, multiple scattering, and complicated physical and geometrical parameters. Notwithstanding these difficulties, it is possible to obtain a useful physical insight into the general form of this law by considering a very simplified model, consisting of a homogeneous atmosphere, in which vertical heights are small in relation to the horizontal distances between town and observatory, and which the scattering is limited to a cone of small angle whose axis lies in the direction of the incident beam. The limited scale height and optical thickness of the real atmosphere, and the forward-scattering characteristics of aerosols lend some plausibility to these simplifications.

  Title Improved scattering formula for calculations of artificial night-sky illumination Type Journal Article
  Year 1984 Publication The Observatory Abbreviated Journal  
  Volume 104 Issue Pages 196-197  
  Keywords Skyglow  
  Abstract In recent years there has been increased interest in measuring the artificial illumination produced in the night sky cities of various sizes at a range of distances from the observer. Examples of such measurements include the work of Treanor on three Italian cities, that of Walker on the cities of various sized in California, and a study by Berry of light pollution in Southern Ontario. There seem to have been few attempts to provide theoretical interpretations of these measurements other than that contained in the paper by Treanor. He developed a simple empirical formula (his equation (6)) for the zenith brigthness due to a distant city as a function of the distance of the observer from the city. Treanor's formula was used by Berry, with a modification which we mention later.

Treanor based his formula on a very ingenious method of estimating the contribution to the zenith brightness of aerosol scattering between the city, treated as a point source, and an element of the atmosphere in the direction of the observer's zenith. Readers are referred to Treanor's paper for details of his derivation. We give here a simple extension of his work which leads to a scattering formula valid under less restrictive assumptions.

  Title Predictions of Future Light Pollution for Ground-Based Observatory Sites Type Journal Article
  Year 1989 Publication Bulletin of the American Astronomical Society Abbreviated Journal  
  Volume 21 Issue Pages 759  
  Keywords Skyglow  
  Abstract In a paper now in press (P.A.S.P. March 1989) we have given details of an improved model for calculating the light pollution caused by one or more cities at an observatory or prospective observatory site. The principal difference in the new model from our earlier one is the inclusion of the effects of the curvature of the Earth, which are significant for the large cities at large distances from mountain observatories.
