Polarization lidar returns from aerosols and thin clouds: a framework for the analysis.
Relationships for the interpretation of polarization lidar observations of aerosols and thin clouds are presented. They allow for the separation of contributions to backscatter from solid and liquid phases by the use of either the classical backscatter and depolarization ratio parameters or the particulate cross-polarized backscatter cross sections. It is shown that different aerosol phases can be better separated by use of the latter coordinates. Emphasis is placed on the study of composition and phase properties of polar stratospheric aerosols.
