Abstract
The results of a large-scale investigation of carbon dioxide and methane distribution carried out in Western Siberia in 2018-2019 using a Picarro G4301 portable gas concentration analyzer are presented. The analysis of the obtained data enabled the spatial distribution of background concentrations of CO2 and CH4 to be retrieved with a high resolution. The revealed inhomogeneities in the CO2 and CH4 distribution is a result of both the effect of ecosystem features in different regions of West Siberia and the characteristics of their seasonal cycles.
