Spatial and Temporal Variations in CO2 Concentration in the Surface Atmospheric Layer of the Territory of the Russian Federation Based on the CAMS Database


Based on the data of the Copernicus Atmosphere Monitoring Service reanalysis, the spatial and temporal variations of the CO2 concentration near the surface on the territory of the Russian Federation for the period 2010–2019 were investigated. It was found that the Southwestern part of the country has high values of CO2 concentrations and anthropogenic emissions. However, the growth over 10 years in this area is minimal. The maximum increase is observed in the Far Eastern, Ural, and Siberian federal districts, reaching values of 2.48, 2.41, and 2.39 ppm/year, respectively. In addition, these parts of the Russian Federation have the highest carbon emissions from fires and the highest soil-temperature changes. This change in temperature can lead to a significant release of carbon stored in permafrost. It is possible that these two factors were responsible for the maximum increase in CO2 concentrations in the area over the period 2010–2019. It was found that, in 2016, for the Ural and Volga federal districts, the increase in the average annual CO2 concentration reached 5.8 and 5.65 ppm, and the amplitude value was 31.73 and 26.07 ppm, respectively. This result may be due to a sharp increase in carbon emissions from fires by 310% in the Ural Federal District, as well as a change in soil temperature by about 0.8°C, which in turn may have increased soil emissions in both regions of the Russian Federation. No significant influence of anthropogenic emissions on the change in CO2 concentration is observed. Thus, it can be concluded that the greatest contribution to the increase in the concentration of carbon dioxide over 10 years is due to its natural sources, such as fires, and soil emissions.
