“…Therefore, to increase the reliability of the reconstructed profiles, we apply aerosol correction. A similar example was examined in detail in [33], where it was shown that, without aerosol correction, the profiles overestimate the ozone concentration in the troposphere.…”

We present a union of three measurement systems on the basis of the Siberian lidar station and mobile ozone lidar. The lidars are designed for studying the ozonosphere using the method of differential absorption and scattering, as well as for studying aerosol fields using elastic single scattering. The systems are constructed on the basis of Nd:YAG lasers (SOLAR) and an Nd:YAG laser (LOTIS TII), a XeCl laser (Lambda Physik) and receiving telescopes assembled using the Kassegrain system with a diameter 0.35 m and the Newtonian 0.5 m system. Lidars operate in photon-counting mode and record lidar signals with a spatial resolution from 1.5 m to 160 m at sensing wavelengths of 299/341 nm in the altitude range of ~0.1–12 km and ~5–20, and at 308/353 nm in the altitude range of ~15–45 km. The union of these three measurement systems was used to carry out field experiments of atmospheric lidar sensing in Tomsk and to present the results of retrieving the vertical profile of the ozone concentration. In this study, coverage of the entire ozonosphere by the lidars was carried out for the first time in Russia.

“…Through DIAL technique, using the analysis of the ratio of the value of the backscattering lidar signals with height, it is possible to determine the distribution of the concentration of molecules of any gas along the path of the laser beam of the lidar, and to record units and tens of gas molecules per trillion air molecules. This technique, actively used in SLS, for recovering the profile of the OVD with the temperature and aerosol correction included is based on the equation from works [27][28][29].…”

“…Therefore, a correction for the temperature dependence should be performed in the algorithm of OVD retrieval from lidar measurements. The retrieval algorithm [29] uses the actual dependence of ozone absorption cross-section on the temperature, obtained using the last experimental and calculation data from works [30,31]. This new dependence is given in Table 1.…”

The purpose of the work is to study the influence of temperature correction on ozone vertical distribution (OVD) in the upper troposphere–stratosphere in the altitude range~(5–45) 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 −0.97 × 1012 molecules × cm–3 at 19.7 km to 1.05 × 1012 molecules × cm–3 at 25.3 km during winter–spring season, and from −0.17 × 1012 molecules × cm–3 at height of 17.4 km to 0.27 × 1012 molecules × cm–3 at 40 km in summer–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 −1.95 × 1012 molecules × cm–3 at 18.6 km to 1.23 × 1012 molecules × cm–3 at 18.2 km during winter–spring season, and from −0.15 × 1012 molecules × cm–3 at height of 11.4 km to 0.3 × 1012 molecules × cm–3 at 8 km during summer–fall season.

“…For instance, air quality in middle and high latitudes declines significantly in winter due to radiative cooling at night and strong inversion near the ground [3]. LiDAR has been used with various technologies to detect atmospheric temperature profiles over the past decade [4], namely the rotational Raman technique, the integration technique, and the resonance fluorescence technique, as well as the high-spectral-resolution LiDAR technique and differential absorption LiDAR. For all-day measurements in the troposphere, rotational Raman LiDAR has proven to be the most reliable technology at present [5,6].…”

The range of detection and accuracy of currently available Raman temperature LiDAR systems are primarily improved by increasing the energy or the aperture of the receiving telescope. However, this does not lead to a corresponding linear increase in the distance of detection and accuracy of the system. In this paper, the authors construct a simulation model and optimize its parameters to develop a Raman temperature LiDAR with low energy and a small aperture that has a maximum distance of detection of over 5 km during the day and over 10 km at night. The profile of the atmospheric temperature obtained through field tests was in good agreement with the results of a radiosonde. The maximum correlation between the Raman temperature LiDAR and the radiosonde was 0.94 at night and 0.81 during the day. The results showed that the proposed Raman temperature LiDAR, with low energy and a small aperture, can provide reliable data on the temperature in the troposphere throughout the day.
