GC21A:
Asia's Non-CO2 Greenhouse Gas Dynamics Under a Changing Environment: Measurement, Experiment, and Modeling Posters

Submit an Abstract to this Session



Session ID#: 23489

Session Description:
Asia is extremely vulnerable to ongoing climate change and human activities (e.g. land use change) and both of these processes have a significant influence on non-CO2 greenhouse gas (CH4, N2O) dynamics. Observed data with adequate spatial and temporal resolution on non-CO2 greenhouse exchange between the atmosphere and biosphere or soil are lacking, making our understanding and predicting of GHG and its responses to rapid land use and climate change very limited. Significant uncertainties also exist surrounding the contribution of Asia ecosystems to global GHG emissions. This session welcomes contributions which provide new observed data on GHG dynamics across spatial and temporal scales and their response to land use or climate change, that use ground based and remotely sensed observations, manipulative experiments, and biogeochemical models to enhance our understanding of the key drivers of biogeochemical cycles from plots to regions, and that link the exchange between the atmosphere and terrestrial ecosystems.
