Research Abstract

Terrestrial submodels in earth system modeling framework contain large uncertainties in its accuracy, which in turn produces large uncertainties in projecting future global environmental changes. In this project, we developed an objective refinement procedure to a terrestrial ecosystem model using satellite-based products, and tested the effects of the submodel refinement on projecting future global changes within earth system modeling framework. We demonstrated that satellite-based land productsare effective in refining terrestrial submodels and the submodel refinement affects future projection of global environmental changes.
