Abstract

This article discusses the results of measurements of the concentrations of carbon dioxide and methane in the surface atmosphere and their fluxes in the atmosphere–aquatic system in the aquatic area adjacent to the western coast of southern Baikal (coordinates 51°54′ N, 105°05′ E). The measurements were carried out in 2012–2023. It is shown that, at the observation point, the flux of carbon dioxide from the atmosphere into the lake per square meter of water surface over the entire period of open water is approximately 100 times higher than the release of methane from the lake into the atmosphere. Taking into account the ratio between these fluxes and global warming potentials (GWPs) of CO2 and CH4, it is concluded that, in the aquatic area, during the period of open water, the carbon dioxide absorption at least compensates the radiative effect of methane emission.
