Abstract :
Cloud lidar data from NASA´s Lidar-Inspace Technology Experiment (LITE) mission and from LANL´s new Wide-Angle Imaging Lidar (WAIL) prototype show that the multiple-scattering theory of off-beam lidar readily explains the observations, as long as internal stratification of cloud density is accounted for. At the same time, predictions for spatial and temporal statistics of the signals are used to infer the optical depth and the physical thickness of the clouds being probed
