報告一：改進的地球系統模擬與數據同化（Improved earth system modeling with data assimilation）
報告人：唐奇 博士
報告內容：Earth system models simulate different compartments like the ocean, atmosphere, surface water and ground water in one framework. Data assimilation for Earth system modeling is challenging due to the complexity of different compartments within the model. We explore the role of data assimilation into the integrated hydrological model and the coupled ocean-atmosphere model. For a river-aquifer system, am improved characterization of spatial-temporal varying riverbed hydraulic conductivity and estimation of river-aquifer exchange fluxes is found with the help of data assimilation. For a coupled ocean-atmosphere system, data assimilation can improve the prediction of the ocean as well as the atmospheric state using either the weakly coupled or the strongly coupled assimilation method.
報告人簡介：Dr. Qi Tang is a postdoctoral researcher in the data assimilation group at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) in Germany. She received her bachelor degree in Applied Mathematics from China Agricultural University and master degree in Hydrology from Beijing Normal University. Afterwards she got her PhD degree in Hydrogeology from RWTH Aachen University in Germany. Since September of 2017 she has been working in AWI for the project ‘Advanced Earth System Modelling Capacity – ESM (http://esm-project.net)’. Her research interests include ensemble-based data assimilation methods for earth system modeling, catchment scale groundwater-surface water interaction system and global ocean-atmosphere modeling.
