+Climate extremes like droughts and heatwaves impact how water, energy, and
+carbon move through ecosystems. To capture the exchange between the land surface
+and the atmosphere, we aim to apply the “STEMMUS-SCOPE” model across ecosystems
+at a global scale. The model STEMMUS simulates soil water and heat, and the
+model SCOPE the vegetation photosynthesis and land surface energy balance.
+
+Like other land surface models, STEMMUS-SCOPE relies on a large number of
+numerical calculations using various meteorological data and surface parameters
+as inputs. To overcome challenges such as computational costs and optimization
+issues in calibration, we developed open-source tools for efficient computing
+and data handling following FAIR guidelines within the context of EcoExtreML
+project. In this project, we improved the representation of
+soil-water-plant-energy interaction in the model, developed a machine learning
+approach to emulate the model, and enhanced the re-usability of the model using
+the Basic Model Interface (BMI).
+
+The technologies developed in EcoExtreML will
+contribute to developing a digital twin of soil-plant systems.
