Some results of the analysis of measurements carried out at Siberian Lidar Station of the Institute of Atmospheric Optics, SB RAS in Tomsk (56.5°N, 85°E) in February and December of 1996, are presented. The complex measurements include lidar measurements of the vertical distribution of ozone (VDO) and temperature (VDT) in the stratosphere, spectrophotometric measurements of the total ozone column (TOC), and vertical distribution and total column of nitrogen dioxide (VD/TC NO2). The analysis of anomalous fluctuations in the ozone observed has shown their good connection with the behavior of circular-synoptical processes on the global scale. It is noted, that the unusual VD NO2 is connected with the positive anomalies in TOC; no explicit relation of the ozone behavior to NO2 at negative anomalies in TOC was found. The comparison of the results obtained with the synoptical ones has confirmed the potentiality of such a complex approach to investigation of the ozonosphere from one observational point.
