Quantifying Spatial Heterogeneities of Surface Heat Budget and Methane Emissions over West-Siberian Peatland: Highlights from the Mukhrino 2022 Campaign

et al.

Abstract: The study presents the first results from the multi-platform observational campaign carried out at the Mukhrino peatland in June 2022. The focus of the study is the quantification of spatial contrasts of the surface heat budget terms and methane emissions across the peatland, which arise due to the presence of microlandscape heterogeneities. It is found that surface temperature contrasts across the peatland exceeded 10 °C for clear-sky conditions both during day and night. Diurnal variation of surface temperat… Show more

“…In addressing potential correlations between environmental factors and F CH4 levels to explain significant emission variability, the present study failed to include soil temperature or heat balance among the measured parameters, which exhibits substantial variations in short spatial scales , and plays a crucial role in driving the bioprocesses within the CH 4 cycle. Future research on the spatial variability of CH 4 cycling can be substantially advanced by incorporating soil temperature along with factors such as oxygen availability, water content beyond the water table depth, and the quality of peat organic matter.…”
