Abstract
The purpose of this paper is to study how the application of different sets of absorption cross-sections influence the ozone vertical distribution (OVD) in the upper layers of the troposphere—stratosphere in the altitude range ~(5–45) km, using a differential absorption lidar (DIAL), operating at the sensing wavelengths 299/341 nm and 308/353 nm. We analyzed the results of lidar measurements of OVD obtained in 2021 using meteorological data from the IASI/MetOp satellite at the Siberian Lidar Station (SLS). The retrieval was performed using the data of four groups concerning the absorption cross-sections: Gorshelev et al., Malicet et al., SCIAMACHY, and GOME. To estimate how the absorption cross-sections influence the OVD retrieval from lidar measurements, we calculated the average deviations between the profiles retrieved using different sets both in a particular case on 2 January 2021 and throughout 2021. Our study showed that, out of the four absorption cross-section sets, the data of Gorshelev et al. should be used for long-term lidar monitoring of the ozone. These data show a more discrete dependence of the absorption cross-sections on the temperature values, which is more urgent for tropospheric and stratospheric ozone measurements.

The problem of remote monitoring of minor gas constituents (MGCs) and aerosols in the atmosphere is urgent for constructing atmospheric models and for controlling Earth’s climate change [1].It is principally important that most of the radiatively active atmospheric constituents, i.e., clouds, aerosols, water vapor, and, especially, the ozone, are interrelated
Using the method of differential absorption and scattering, with the incorporation of the actual temperature measurements from meteorological satellite of the European Space Agency (MetOp) and different sets of absorption cross-sections into the retrieval algorithm, we calculated the average ozone profiles for the stratosphere and UTLS. We used those results for analysis to clarify precisely how different absorption cross-sections will influence the long-term measurements of the vertical distribution of ozone concentration
Summary
It is principally important that most of the radiatively active atmospheric constituents, i.e., clouds, aerosols, water vapor, and, especially, the ozone, are interrelated. This results in an increase in the atmosphere of the strongest photooxidants. The increase of the temperature near the Earth’s surface is known to be accompanied by temperature decrease in the troposphere, stratosphere, and mesosphere [3,4]. This should result in an increased probability of re-condensation clouds: cirrus clouds in the troposphere, nacreous clouds in the stratosphere, and noctilucent clouds in the mesosphere. From the viewpoint of the atmospheric radiation budget, the main climate-forming factors are cloud and aerosol fields, as well as greenhouse gases and, primarily, ozone and gas components of ozone cycles. It should be noted that stationary lidar stations, similar to the Siberian Lidar Station (SLS), operate in different parts of the world: Tsukuba (36.05◦ N, 140.13◦ E), Japan [5,6]; Observatoire de Haute Provence (OHP) (43.94◦ N, 5.71◦ E), France [7,8]; Hefei (31.82◦ N, 117.22◦ E), China [9,10]; Table
