Session Proposal: Advances in Measurements, Synthesis, Analysis and Modeling of Greenhouse Gas Fluxes from Natural Ecosystems (AGU25)

B003
Advances in Measurements, Synthesis, Analysis and Modeling of Greenhouse Gas Fluxes from Natural Ecosystems

Session ID#: 252342

Session Description:
A better understanding and modeling of greenhouse gas (GHG) fluxes from natural ecosystems is essential for more reliable climate-change projection, mitigation, and adaptation. However, current estimates of natural GHGs remain highly uncertain. This session highlights observations, synthesis, mechanistic understanding, and upscaling/modeling of GHGs from natural ecosystems, including wetlands, freshwater systems, forests, and grasslands. Specifically, the topics include but are not limited to:- Measurements of CO2, CH4 and N2O fluxes and their key drivers;- Data synthesis regionally and globally;- Understanding the mechanisms and spatiotemporal patterns of GHGs;- Upscaling/modeling of GHGs using machine learning, remote sensing top-down inversion, and bottom-up biogeochemistry models
