Abstract
The gradient measurements of the concentration of atmospheric carbon dioxide and methane in the middle taiga subzone of the Yenisei region of Siberia based on five years monitoring (2009–2014) at the ZOTTO Observatory are presented. The features of changing of the content of carbon dioxide and methane in the profile heights up to 301 meters is explained by both daily and seasonal specificity of functioning of terrestrial ecosystems and atmospheric processes. It is shown that in the cold season CO2 and CH4 concentrations in the surface atmosphere change synchronously and are determined by their sources and weather conditions. The results of measurements of methane concentration are compared with those obtained in other areas of Siberia on similar latitude and with measurements on background stations of Russia.
