专家简介：Professor Dr. Bob Su (University of Twente) is an internationally recognized expert in spatial hydrology, earth observation, and land-atmosphere interactions with 30+ years' experience. He holds the chair of Spatial Hydrology and Water Resources Management, previously leading UT's Water Resources Department for 15 years. His research integrates water-energy-carbon processes using remote sensing, modeling, and machine learning for climate/ecosystem applications. Bob Su has held leadership roles at initiatives by ESA, GEO, EGU, and WCRP/GEWEX, advising major satellite missions (e.g., ROSE-L) and steering global hydrology initiatives. He pioneered capacity-building programs (e.g., ESA Dragon/TIGER), supervised 37+ PhDs, and led 54 funded projects. His work advances digital twin earth and soil-plant-atmosphere continuum modeling.

报告介绍：Earth’s water, energy, and carbon cycles are intricately coupled through soil-plant-atmosphere interactions that regulate climate and ecosystem dynamics. Climate change amplifies the critical importance of these linkages in understanding and predicting extreme events, as evidenced by the 2021 European floods and the subsequent 2022 drought. The European Space Agency’s (ESA) new Earth Observation Science Strategy (ESA, 2024) confronts this complexity, advocating a holistic approach via six overarching science themes—the water cycle, the carbon cycle and chemistry, energy fluxes, ecosystem health, extremes and hazards, as well as Earth system interfaces and coupling. Among the twenty-three science questions, two questions — “What governs the coupling of Earth’s energy, water, and carbon cycles?” and, “How do anthropogenic influences alter the water cycle?” — emphasize soil-plant dynamics as a nexus for coupling Earth’s water, energy, and carbon cycles, advancing Earth system science and sustainability. I will present our new digital twin framework, STEMMUS-SCOPE, centered on the soil-plant system, leveraging Earth Observation to close the water cycle and integrate it with energy and carbon dynamics, with photosynthesis and water potential as the unifying mechanism. Some insights from applying this system to different ecosystems will be discussed.
