Paper Abstract

The interannual variability and rate of change of the total methane content in the atmosphere are studied in the Western Siberia zone (45°-65° N, 60°-90°E), which covers almost all the wetland complexes of the region, over the period 2003- 2017. The retrieval of the gas content was carried out using the regression model constructed by the authors and the data of the AIRS hyperspectrometer of the Aqua satellite. It was found that the total methane content has winter (January/February) and summer (July-September) peaks in each annual cycle for the period considered. It is shown that the content of methane in the atmosphere increased at a rate of ~ 3.3 ppb/year during this period.
