Groundwater in Earth system Models
I-GEM: Impact of Groundwater in Earth systems Models
Our main goal is to explore the impacts of groundwater (GW) on regional and global climate, and its links to water resources availability, through model analyses. To this end, our Franco-Taiwanese consortium offers a unique opportunity to compare the sensitivity of simulated climate to different GW parametrizations within 3 different climate models: the French IPSL and CNRM-GAME climate models, and the American NCAR climate model (CESM), modified and used here by the Taiwanese team at NTU (National Taiwan University)... learn more
