Abstract : A three year program developing and utilizing lidar techniques for atmospheric research is described. This included an investigation of the use of a nitrogen fluorescence lidar as a diagnostic tool during ionospheric RF heating experiments. During 1993 an experiment was performed using our lidar transmitter at the AMOS facility on Mt. Haleakala in Hawaii. Using one of the AMOS telescopes as a receiver data was taken using Rayleigh backscatter and Raman channels as part of the ALOHA '93 campaign. Progress was made toward the development of an intracavity-summed multiple-wavelength Nd:YAG laser for use in a sodium lidar system. Work was initiated to modify the trailer lidar system to include an ozone DIAL capability. (AN)
