Abstract : SRI International operated a van-mounted four-wavelength lidar system during the July 1990 FLAPIR field experiment. Measurements of range-resolved relative backscatter signatures were obtained at wavelengths 0.53, 1.06, 3.8, and 10.6 um. Backscattered signals from a passive reflecting target located 928 m from the SRI lidar van were used to estimate path-length transmission values at wavelengths 0.53, 3.8, and 10.6 um during selected time periods. Lidar data files were transferred to a MicroVax computer and copied to a single optical disk medium that was provided to Phillips Laboratory (GP). At the request of Phillips Laboratory, an identical copy was also sent to Dr. Luc Bissonnette of Defense Research Establishment Valcartier for subsequent data analysis.
