Abstract:

Crystal (cirrus) clouds were observed with the polarized lidar LOSA-S. Layers with particles, preferably oriented in the horizontal plane, demonstrate the mirror-like reflection. It is shown that element a44 of the normalized backscattering phase matrix (BSPM) can be measured. Results of measurements are independent of the presence or absence of the azimuthal particle orientation. Temporal and spatial variability of the orientation of crystal particles is demonstrated. Results of using both linear and circular polarization are compared. Specular reflection from single crystal particles can be recorded.
