The detection and recording of atmospheric scattering data has received a tremendous amount of attention since the development of the laser. The work of such men as Myron Ligda and Ron Collis at the Stanford Research Institute and Georgio Fiocco at MIT has shown that the laser radar (or LIDAR) is a valuable tool for obtaining backscatter information on atmospheric phenomena. The General Electric Company has been actively engaged in laser measurements of the atmosphere since 1964. (Ref..1,2) A number of laser equipments were con-structed and used to obtain atmospheric data at various places in the country. Recently a large laser system was built for use in measuring Rayleigh and Raman scattering in two colors from the atmosphere by the Space Sciences Laboratory of the General, Electric Company in King of Prussia, Penn sylvania. The two color capabilities of the of the system are used to obtain data on the differences between Rayleigh and Mie scat tering which exhibit diffijirent scattering func tion at different wavelength.
