Researchers have developed Earth-o1, a novel atmospheric world model that operates directly on ungridded observational data, bypassing traditional spatial grid limitations. This observation-native approach learns the Earth system's physical evolution without relying on conventional dynamical modeling or data assimilation. The model demonstrates real-time forecasting capabilities and achieves surface forecast skill comparable to the operational Integrated Forecasting System (IFS). Earth-o1 represents a new class of geophysical simulators, offering a scalable, data-driven foundation for a digital twin of the Earth. AI
