The importance of decarbonization of industrial enterprises in the Volgograd region

The article presents the influence analysis of industrial enterprises of the Volgograd region on the state of atmospheric air in the region. The importance of solving the problem of greenhouse gas emissions into the atmosphere at the international level has been analyzed. Foreign experience in terms of reducing carbon dioxide emissions of industrial enterprises is considered. A method to reduce the environmental burden on atmospheric air by decarbonization, i.e. сarbon capture and storage of CO2 in deep geological objects is proposed.

Ecological and sanitary condition of the Voronezh water reservoir under “blooming” conditions based on materials from 2016–2022

The aim. Study of the ecological state of the Voronezh reservoir under conditions of “blooming” of water by cyanobacteria. Materials and Methods. EEvaluating water quality data of hydrochemical analysis, assessment of suspended solids distribution and temperature in the water area, materials of hydrobiological study (phytoplankton), microcystin content in water have been taken into account. Results and Discussion. The direction of anthropogenic changes occurring in the ecological state of the reservoir has been traced for 2016–2022.

GIS technology in the reconstruction of trade and transport system of the Golden Horde

The article discusses the issues concerning historical reconstruction of trade and transport system of the Golden Horde based on the data analysis with the use of geographic information systems, logistics modeling and interdisciplinary technologies.

Monitoring of annual variability of thunderstorm activity for climatic stations of Western Siberia

The article presents the study results of the annual variability of thunderstorm activity at nine climatic stations in Western Siberia over a fifty-year period from 1971 to 2020. The study revealed a complex quasi-periodic structure of thunderstorm activity series with the most pronounced amplitude of 7–8-year cycles for the forest-tundra and a 2–4-year cycle for the taiga zone, as well as forest-steppes.

Evaluating the statistical significance of air temperature changes in the Northern hemisphere by statistical methods

The analysis of changes in the near-surface air temperature of the Northern Hemisphere is given. To identify years in which there was a violation of the series homogeneity, the stepwise trend method was applied using Kolmogorov statistics. It is shown that the identified homogeneous climatic intervals basically correspond to the natural climatic periods of the state of the Earth’s climate system. The assessment of the significance of temperature changes in homogeneous climatic areas was carried out by the method of confidence intervals using Student’s t-test.

Internet as an element of modern social infrastructure: Sociological and territorial aspects

The article is devoted to the analysis of the ways of using and accessing the Internet. In the course of the study, a sociological survey of respondents living in the city of Saratov was conducted, the results of which were compared with the average Russian statistical data.

Assessing the continentality index of Western Siberia against the background of regional climate change

Quantitative assessment of the territory continentality is an urgent task, because in the conditions of climate change, the index of continentality can be taken into account when developing geographical forecasts of landscape development. The purpose of this study is to assess the change in the index of continentality of Western Siberia in the conditions of the current trend in climate development. The statistical series of observations on seven meteorological stations in Western Siberia served as the information base of the study.

Assessment of future Central African air temperatures under the CMIP5 and CMIP6 project scenarios

Based on the results of the historical experiment of the CMIP5 and CMIP6 projects, the effectiveness of the scenario estimates (RCP/SSP1 2.6, RCP/SSP2 4.5 and RCP/SSP5 8.5) of the future air temperature for Central Africa for the IPSL and BCC global climate models is evaluated and the simulation results of these projects are compared with each other and with the observations of meteorological stations in the region, both for the historical experimental period and with the observations of recent years for the implementation of future climate projections.

Medico-geographical analysis of the incidence of colorectal cancer

The article discusses the issues of territorial prevalence of colorectal cancer in Saratov. A statistical analysis of morbidity and an oncogeographical analysis of urban landscape sites were carried out. The study of the regional features of the spread of this pathology, taking into account risk factors, will help in the development of the direction for the active search for patients.

Geoportals as a tool for access to cloud storage of metageosystems data

The article is devoted to solving the scientific problem of spatial data storage management using geoportal systems on the basis of solving the scientific problem of analyzing the patterns of spatiotemporal organization of complex dynamic hierarchically organized metageosystems. The paper proves that the problem of integrating large arrays of spatial information in spatial data infrastructures (SDIs) can be solved by designing multi-model storages operating on the basis of database management systems of different classes.
