Lidar and satellite measurements of the vertical ozone distribution at the Siberian lidar station: profile retrieval and estimation of results

At the Siberian lidar station, long-term measurements of the ozone vertical distribution are continued at the sensing wavelength pairs of 299 and 341 nm, 308 and 353 nm. The report presents a quasi-three-year seasonal model of vertical ozone profiles formed in recent years, obtained using the differential absorption lidar complex of the Siberian lidar station and the Aura, MetOp satellites in the upper troposphere - stratosphere. A typical seasonal feature of the vertical ozone distribution in Western Siberia is presented. The ozone profiles were retrieved using the vertical temperature distribution from the meteorological satellite data. We analyzed how the existing sets of absorption cross sections influence the deviation of the ozone profiles, retrieved with their application, from the Krueger model and the quasi-three-year model. Since 2021, measurements have been performed at the lidar station with different spatial resolutions from 10 m to 100 m. An analysis and estimation of how different spatial resolutions influence the error of retrieving ozone profile from lidar and satellite measurements in 2021 was conducted.
