CarboEastAsia: Capacity building among ChinaFLUX, JapanFlux and KoFlux to cope with climate change protocols by synthesizing measurement, theory and modeling in quantifying and understanding of carbon fluxes and storages in East Asia.
Knowledge of the carbon dynamics of the terrestrial ecosystems in East Asia is essential to advance our understanding of global carbon and water budgets and prediction of the impacts of climate change. This project will bring together scientists from China, Japan and Korea to evaluate and integrate carbon and water flux measurements made in individual countries, and to up-scale site-specific results, to regional, national and finally entire East Asia by implementing following activities: inter- and multi-disciplinary joint field investigation, networking flux measurements (inter-site comparison), model development, parameterization and validation, up-scaling, and integration efforts, seminar and science meetings, its major objectives are to:
- identify important mechanisms，both natural and anthropogenic, that drive carbon cycling in various terrestrial ecosystems, natural and managed;
- quantify the distribution and strength of carbon sink/source, and their spatial and temporal variability and uncertainty;
- examine functional type of vegetation and its spatial distribution pattern, carbon assimilation processes and its driving mechanisms, and interactive relationship between vegetation type and carbon cycle;
- develop a new generation of carbon cycle models suitable to the east Asian ecosystems;
- evaluate influences of land use and climate changes on carbon cycle of ecosystems;
- establish datasets that are reliable and consistent for estimating regional carbon fluxes and storages in East Asia by combining field observations, manipulative experiments, and data-model fusion;
- provide scientific insights into carbon sequestration potentials of the terrestrial ecosystems, and political suggestions on reduction in carbon emissions; and
- quantify the contribution of terrestrial ecosystems in East Asia to global carbon balance.
