Paper Abstract

Seasonal cycle and interannual variability of methane content in the mid-upper troposphere has been investigated over Western Siberia domain in 2003-2015. This region concentrates significant sources of CH4 of both natural (wetland) and anthropogenic (gas and oil extraction and distribution) types. The study was based on the measurements of the Atmospheric Infrared Sounder/Advanced Microwave Sounding Unit (AIRS/AMSU) aboard NASA's Aqua satellite. It was found that mixing ratio of methane has a maximum in winter (January-February) and in summer-autumn (July- September) in every year cycle for the period mentioned above. It was shown that methane content in mid-upper troposphere over Western Siberia increased with the rate of ~4.7 ppbv/yr in this period.
