Abstract
The paper presents the methodology, results, and analysis of routine methane measurements in the atmospheric surface layer at a remote integrated background monitoring station in the Prioksko-Terrasny Biosphere Reserve (PTBR). The analysis of seasonal variability in atmospheric methane over the background area, the quantification of its changes and a trend for the entire observation period (2006–2020) are provided. According to long-term data, there is a summer minimum of averaged methane concentrations in the annual cycle, while the maximum is observed in winter. The mean methane level at PTBR is 5–10% higher than global mean background methane concentrations. An evaluated linear trend toward the methane growth at the PTBR is \(\sim\)2 ppb per year, which is lower than the global mean rate.
