The purpose of the work is to study the influence of temperature correction on ozone vertical distribution (OVD) in the upper troposphere&ndash, stratosphere in the altitude range~(5&ndash, 45) km, using differential absorption lidar (DIAL), operating at the sensing wavelengths 299/341 nm and 308/353 nm. We analyze the results of lidar measurements, obtained using meteorological data from MLS/Aura and IASI/MetOp satellites and temperature model, at the wavelengths of 299/341 nm and 308/353 nm in 2018 at Siberian Lidar Station (SLS) of Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences. To estimate how the temperature correction of absorption cross-sections influences the OVD retrieval from lidar measurements, we calculated the deviations of the difference between two profiles, retrieved using satellite- and model-based temperatures. Two temperature seasons were singled out to analyze how real temperature influences the retrieved OVD profiles. In the stratosphere, when satellite-derived temperature and model are used for retrieval, the deviations may reach absolute values of ozone concentration in the range from &minus, 0.97 ×, 1012 molecules ×, cm&ndash, 3 at 19.7 km to 1.05 ×, 3 at 25.3 km during winter&ndash, spring season, and from &minus, 0.17 ×, 3 at height of 17.4 km to 0.27 ×, 3 at 40 km in summer&ndash, fall period. In the troposphere, when satellite-derived temperature is used in the retrieval, the deviations may reach absolute values of ozone concentration in the range from &minus, 1.95 ×, 3 at 18.6 km to 1.23 ×, 3 at 18.2 km during winter&ndash, 0.15 ×, 3 at height of 11.4 km to 0.3 ×, 3 at 8 km during summer&ndash, fall season.
