This paper describes procedures for taking solar aureole photographs with conventional small format (35-or 70-mm) cameras and films and discusses photographic-photometry techniques for obtaining accurate solar aureole radiance measurements from these photographs, the measurements being used for retrieving atmospheric aerosol characteristics. The photographic data reduction techniques discussed here include sensitometry, densitometry, off-axis illumination distribution measurement, photogrammetry and photometry relations, etc. Comparison tests show that photographic measurements of the solar aureole radiance agree well with simultaneous photoelectric measurements.
