Knowledge of the impact of climate change and rising CO2 on greenhouse gas (GHG, e.g. CO2 and CH4) fluxes from wetlands ecosystems is critical for setting targets for GHG emission reductions and to identify and promote mitigation strategies. Alarmingly, large disagreement exists between estimates from process-based models, atmospheric inversions, and observations. A critical step to move forward our understanding and our predictive abilities of the global biogeochemical cycles, and of the sensitivity of terrestrial GHG fluxes to climate change, is to reconcile the large gap between experimentalists and modellers.
This session will gather studies investigating the controls and predictions of GHG fluxes from chamber measurements, eddy tower data, remote sensing, and modelling, with the ultimate goal of bringing all these communities together, and starting a discussions among these different ways of doing science.
