Lidar polarization study of clouds in case of occlusion front

In this work, experimental data of a lidar polarization study of cloud formations in a case of warm occlusion front in winter are presented. The changes in the low clouds at the different stages of the front advection are followed: before, during and after the cold air mass settles down. The experiment was carried out using a polarization lidar with variable viewing angle of the receiver which allows the influence of the multiple scattering on the signal depolarization to be estimated.
