Earth System Digital Twins are a powerful approach for understanding interacting Earth systems and informing decisions. ESDTs continually update computational representations with timely observations to reflect current state, generate forecasts, and run “what-if” scenarios, enabled by surrogate models, novel AI (e.g., GeoAI, LLMs), interoperable model coupling, continuous data integration, and uncertainty quantification. ≥3D visualization—including VR/MR/AR/XR, spatial computing, sonification, and haptics—provides an ideal intuitive presentation of Earth and space data in their inherently multidimension. In addition, immersive and auditory modalities reveal structure, couplings, and uncertainty that 2D views may miss. This session convenes practitioners to share research, methods, and demonstrations that provide best practices for accessible, available, and adaptable interactions to bridge prototypes into everyday tools for decision-maker-oriented information. Topics include decision support applications, what-if and impact projections, interface and sonification design, interoperable and scalable model coupling, and evaluation of usability and effectiveness. Live demos welcome—bring a headset.
