Spatial and time variability of global and zonal average total ozone (TO) fields are analyzed based on satellite data from databases SBUV Merged Total And Profile Ozone Data, Version 8.6 (V86) for area 60°S – 60°N and Bodeker Scientific Combined Total Column Ozone Database (BS) for area 90°S – 90°N for 1979-2012. The relative deviations (V86-BS)/V86 for 60°S – 60°N between seasonal mean zonal means at 60°S – 60°N do not exceed 3%. Values of the linear trends are close to zero near to equator. Maximum negative trends are observed close to (50-60)°S and reach -0.6 DU/year. The zonal mean trends for BS coincide with the trends calculated for V86 in limits of an error, and the systematic deviation of trends or a drift does not exceed 0.1 DU/year for the majority of zonal bands. Phases of short-period and long-period oscillations are well agreed. For globally – averaged monthly mean TO values for 60°S – 60°N (V86) and 90°S – 90°N (BS), the phase of annual oscillation for BS is ahead of that for V86 by approximately three months. The BS and V86 phase relations agree well enough for quasi-biennial oscillations and oscillations with periods more than 70 months.
