The purpose of this work is to present technologies developed in the Altai State University aimed at monitoring greenhouse gases in the atmosphere of Western Siberia.

Methods. The total methane content in the region’s atmosphere was reconstructed using a regression model trained on data from the AIRS hyperspectrometer of the Aqua satellite as well as the results of the MOZART-4 chemical transport model modified by the authors. To obtain estimates of the total carbon dioxide content in the atmosphere of the Western Siberia south, data from the orbital carbon observatories OCO-2 and OCO-3 were used. Quantitative estimates of the nitrogen dioxide content in the troposphere of the region were obtained from data from the TROPOMI spectroradiometer of the Sentinel-5 Precursor satellite. Emissions of carbon dioxide by large industrial centers of the region were obtained from orbital carbon observatories and the TROPOMI/Sentinel-5P radiometer data. Estimates of gross and net primary production for the region were obtained from data from orbital carbon observatories and the ECOSTRESS radiometer.

Results. The analysis of satellite data on the content of CH4, CO2 and NO2, carried out by the authors, allowsestablishing a number of significant features in the dynamics of the behavior of these gases in the atmosphere of Western Siberia for the first time.

Conclusions. The novel results obtained by the authors on the content of greenhouse gases in the atmosphere of the region of Western Siberia are consistent with both estimates and conclusions published annually in the bulletins of the World Meteorological Organization, reports of the Global Carbon Project and research results published in the literature for other regions.
