It is shown that the using circularly polarized laser radiation and measuring the fourth Stokes parameter of scattered light offer certain advantages over the universally accepted measurements that use linearly polarized sounding. This eliminates the uncertainty in lidar depolarization, which may appear due to some spatial ordering of particles in a cloud. In addition, measurement of the fourth or second Stokes parameter of the scattered light at circular polarization of laser radiation has some promises in distinguishing between the plate and columnar crystals.
