arXiv:2605.14285v2 Announce Type: replace-cross Abstract: Data assimilation (DA) estimates the state of an evolving dynamical system from noisy, partial observations, and is widely used in scientific simulation as well as weather and climate science. In practice, filtering methods rely on frame-to-frame transition models. However, these models are fragile when observations are non-Markovian (when they form only a partial slice of a higher-dimensional latent state as in real-world weather data): they tend to accumulate errors over long horizons. At the same time, learned DA methods typically co
The continuous advancements in AI, particularly diffusion models, are being applied to complex scientific problems like data assimilation, improving predictive capabilities.
Improved data assimilation methods lead to more accurate and robust predictions in critical fields like weather forecasting, climate modeling, and scientific simulations, impacting resource management and disaster preparedness.
The development of unified and robust data assimilation via diffusion forcing offers a new paradigm for handling noisy and partial observations in dynamic systems, potentially reducing long-term error accumulation.

More accurate and reliable long-term forecasts for weather and climate events become possible.
Better predictive models can inform policy decisions, infrastructure planning, and agricultural strategies, mitigating risks associated with climate change.
The success in scientific simulation could accelerate the application of similar AI techniques to other complex systems, including economic or social modeling.
