Abstract : The PHOTOREK II Project, a study of photographic contrast reduction as a function of altitude, wavelength, and meteorological conditions, is discussed. The source of photographic contrast reduction by the atmosphere and a survey of previous efforts in this area are presented. The experimental plan and the targets, photometers, cameras, and meteorological equipment used to obtain contrast reduction and weather data are described. The processing and analysis of the data are presented in detail. The use of scattering theory in conjunction with meteorological factors is illustrated and the results obtained to date are presented. Conclusions and recommendations for future improvements and refinements of the experiment are included. (Author)
