In this paper we discuss the application of well-known, mathematically simple smoothing procedures to retrieve vertical distribution of stratospheric ozone from lidar sensing data. The procedures include linear and exponential smoothing, linear approximation, and hybrid algorithms. The vertical ozone profiles, obtained using these techniques, are compared with the ozone profile retrieved using the method of spline approximation, mathematically justified for solving such tasks. Analysis is presented for the mean summer 1998 profiles and their interlevel correlations.
