## 2 An Overview of the Published Articles
The next article \"Climatology of 557.7 nm Emission Layer Parameters over South-East Siberia, Observations and Model Data\" is concerned with higher layers of the atmosphere. In the study, a detailed analysis of long-term (2002-2022) variations in the intensity of atomic oxygen's luminescence in the 557.7 nm line and the night temperature in the mesopause region was performed. These characteristics were evaluated based on measurements by the 10-channel SABER radiometer installed on board the TIMED satellite. This radiometer covers a spectral range of 1.27-17 microns. The data from these measurements are the basis for obtaining vertical distributions of kinetic temperature, pressure, geopotential height, the density volume ratio of \(O_{3}\) (ozone), the emission intensity of OH (hydroxyl) and the concentration of \(O_{2}\) (mol. oxygen). The article \"Measurements and Evaluations of the Atmospheric Transparency at Short Millimeter Wavelengths at Candidate Sites for Millimeter- and Sub-Millimeter-Wave Telescopes\" is devoted to the study of the astroclimate. In particular, the astroclimate in the millimeter to submillimeter range is considered. One of the main tasks that the authors were working on is the search for new sites for radio telescopes, which must have an atmosphere with good transparency with respect to millimeter and submillimeter waves [11]. The authors provided results of their comparison of candidate sites for millimeter-wave telescopes in northeastern Eurasia. Different methods for the determination of precipitable water vapor, including artificial neural networks, are discussed. Two papers--\"Influence of Atmospheric Flow Structure on Optical Turbulence Characteristics\" and \"Simulating Atmospheric Characteristics and Daytime Astronomical Seeing Using Weather Research and Forecasting Model\"--are related to the improvement of methods describing the astro-optic and astroclimatic characteristics of the atmosphere. The papers demonstrate the possibility of using the mesoscale WRF model to describe meteorological characteristics at the Large Solar Vacuum Telescope (LSVT) site. The authors presented their simulation results within the Baikal region. The outer domain is 1600 by 1600 km, with a horizontal resolution of 8 by 8 km. The dimensions of the two internal domains are 400 by 400 km and 100 by 100 km, respectively. The horizontal resolution of the inner domain was 500 by 500 m. This modeling was performed for conditions with low average surface wind speeds (1-3 m/s) and for conditions with total cloud cover up to 0.3. It is shown that the selected parameterization schemes for the atmospheric boundary layer (Yonsei University scheme) and the surface layer (MM5-similarity scheme) make it possible to satisfactorily reconstruct variations in wind speed. In order to verify the modeling data on the vertical gradients of the air temperature and vertical shifts in wind speed, measurements of the centers of gravity of solar subimages were carried out synchronously with mesoscale modeling. The analysis of the centers of gravity of the solar subimages was carried out using a well-known differential technique to eliminate the influence of the telescope structure's mechanical vibrations. The amplitude of the temporary changes in the solar subimages' centers of gravity is determined by the evolution of turbulent fluctuations of the air refractive index in the direction of radiation propagation. It is shown that the WRF model, despite describing the time variations in the integral of the turbulence energy well (with a correlation coefficient of 0.9), significantly underestimates the amplitude value of the integral along its height. Additionally, important results have been obtained in atmospheric and adaptive optics. \"A Real-Time Measurement System for Atmospheric Turbulence Intensity and Distribution Based on the GLAO System\" is devoted to measuring optical atmospheric turbulence using solar adaptive optics.
