  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.
