Accounting for multiple scattering in retrievals from space lidar

Multiple scattering effects on signals from space lidar are significant and must be accounted for in the retreival of aerosol and cloud extinction. It is shown that a simple parameterization of multiple scattering allows one to account for multiple scattering effects using a slightly modified form of a commonly used single-scatter retrieval solution. All orders of scattering are considered in the development of parameterizaiton appropriate for the CALIPSO lidar. Applications to aerosol and cloud retreivals are discussed.
