Outline of Final Research Achievements

A physical model (PM) was developed to provide accurate and fast estimates of the time-space dependent multiple-scattered backscattered signal from space-borne lidars based on an analytical expression for the high-order phase function and on the path integral approach. Intensive error analyses showed that the estimated lidar observables by the PM over time and the actual range showed good agreement with Monte Carlo simulations.
