Conference paper


A number of light scattering methods have been used to investigate the molecular and particulate content of the atmosphere. They include the searchlight probe studies of Elterman (1954) and Friedland, Katzenstein, and Zatzick (1956), the twilight scattering studies of Volz and Goody (1962) and the aureole photometry of Newkirk and Eddy (1964). With the advent of the high powered ruby laser, optical radar studies of the atmosphere have been made by Fiocco and Smullin (1963), Fiocco and Grams (1964), Clemensha, et al (1965), Bain and Sandford (1966), and Collis and Ligda (1964). Collis (1964) using a ground-based laser radar system observed “ghost” returns from apparently clear air and suggested that they were caused by stratified aerosol layers. It was also suggested that these returns could be used to map effects of air motion and possibly provide an indication of clear air turbulence (CAT). Franken et al (1965) used an airborne system to investigate the correlation between laser returns and clear air turbulence with inconclusive results.
