The paper presents the algorithm of interpreting the light backscattering matrices (BSM) that were obtained by the unique high-altitude polarization lidar of NR TSU while sounding cirrus clouds. The microphysical properties of cirrus clouds, i.e., size, spatial orientation, shape, and percentage of different particles based on BSMs calculated within physical optics approximation were estimated.
