Methane emissions from land and aquatic ecosystems in Western Siberia: An analysis with methane biogeochemistry models [version 1.0]

Western Siberia contains extensive wetlands and aquatic ecosystems, contributing a significant amount of methane (CH4) emissions to the atmosphere. However, estimates of CH4 fluxes over the region are poorly constrained partly due to the uncertainties from the inundated area data. This study applied...

Description
Summary:Western Siberia contains extensive wetlands and aquatic ecosystems, contributing a significant amount of methane (CH4) emissions to the atmosphere. However, estimates of CH4 fluxes over the region are poorly constrained partly due to the uncertainties from the inundated area data. This study applied two process-based biogeochemistry models (Terrestrial Ecosystem Model, TEM; and Arctic Lake Biogeochemistry Model, ALBM) to quantify the emissions from land and aquatic ecosystems separately over the region within the period 2000-2021 using different inundation datasets. We use two wetland data to drive land methane modeling and three inundation data to drive lake methane modeling. We conduct different simulations to compare emissions over the region using these datasets. This study is among the first to investigate methane emissions from the whole landscape and make the quantification from land and aquatic part separately in the region. This study highlights the importance of dynamic wetland and aquatic area data in quantifying regional and global methane emissions.
