## 2 An Overview of the Published Articles  
In the article \"Subsea Methane Hydrates: Origin and Monitoring the Impacts of Global Warming\", the authors examine the structure of the underwater permafrost on the Arctic shelf, taking into account changes in sea level over the past 200,000 years. The presence of climatic changes in the degradation of underwater permafrost and in conditions for the stable existence of subsea methane hydrates in bottom sediments are considered. The East Siberian shelf is chosen as an example here. In order to predict the possibility of developingdangerous climatic scenarios, a method for the seismic monitoring of the state of gas hydrates is proposed, based on solving multiparametric inverse seismic problems. The article entitled \"Crustal Apparent Density Variations in the Middle Segment of the North Tianshan Mountains and Their Tectonic Significance\" contains interesting results for the development of our understanding of spatial inhomogeneities in the gravitational field, the formation areas of anomalous pre-seismic signals and earthquake preparation zones. The authors discuss the spatio-temporal variation pattern of the local gravity field within the middle segment of the North Tianshan Mountains. Their comparison of earthquake clusters and gravity anomalies indicates there is a certain relationship between them. Another study, \"Earthquake Prediction for the Duzce Province in the Marmara Region Using Artificial Intelligence\", also aimed at the study of earthquakes. [PERSON] et al. have used a recurrent neural network (RNN) for the prediction of earthquakes within the Duzce Province of the Marmara Region. In order to train their RNN, they used seismic data (earthquake magnitude, latitude, longitude and depth) provided by the Kandilli Observatory. For the improvement of their RNN, the authors proposed special coefficients depending on the intensity and the number of earthquakes occurring within a space-limited earthquake zone. In the paper \"Atmospheric Electricity Measurements in the Pacific Northwest, Russia\" [PERSON] discusses the main reactions of the electric field to meteorological phenomena and seismic and space events. The work discusses the well-known connection between anomalies of the electric field potential gradient and earthquakes [8]. It is indicated that Paratunka Observatory is an excellent site for the accumulation and processing of data in order to study the relationship between atmospheric electricity and earthquakes. It is also worth noting that, currently, measurement data continue to accumulate. In this Special Issue, a number of studies are devoted to the study of the atmosphere's microphysical and optical characteristics, as well as the effects of the underlying surface. In particular, [PERSON] et al. presented the paper \"Ecological Zoning of the Baikal Basin Based on the Results of Chemical Analysis of the Composition of Atmospheric Precipitation Accumulated in the Snow Cover\". This study was carried out on the ecology of Lake Baikal [9]. Based on the statistical processing of data and the direct sampling of snow cover, an inventory of the sources affecting the composition of atmospheric precipitation in the region was performed. In the study, the authors separately examined 14 districts. For each district, a set of predominant tracer pollutants was obtained. The study entitled \"Parametric, Semiparametric, and Semi-Nonparametric Estimates of the Kinetic Energy of Ordered Air Motion and Wind Outliers in the Atmospheric Boundary Layer from Minisodar Measurements\" expands our understanding of the energy picture in the lower layers of the atmosphere [10]. In particular, the study was carried out within the lower (200 m) part of the atmospheric boundary layer. Using novel approaches developed by the authors, the results of a study of the wind velocity field are presented with high vertical resolution. Vertical changes in the average kinetic energy and kinetic energy of turbulent air flowsare considered separately.
