PROBLEMS AND METHODS OF THE ABSOLUTE PHOTOMETRY OF NOCTILUCENT CLOUDS.
Abstract
The object of investigating noctilucent clouds by photometric methods is to obtain optical characteristics of the cloud-forming aerosol which will permit the formulation of conclusions concerning the chemical composition and physical state of the dispersed particles. Among these characteristics are: (1) the scattering indicatrix, which expresses the directional distribution of the scattered light; (2) variation of the scattering coefficient with wavelength; (3) variation of extinction along the spectrum; (4) polarization of the scattered light; and (5) the character of such luminescence as may exist in the medium.
