Omni-Weather: Unified Multimodal Foundation Model for Weather Generation and Understanding

ICLR 2026poster

Weather modeling requires both accurate prediction and mechanistic interpretation, yet existing methods treat these goals in isolation, separating generation from understanding. To address this gap, we present Omni-Weather, the first multimodal foundation model that unifies weather generation and un…

Align-DA: Align Score-based Atmospheric Data Assimilation with Multiple Preferences

NeurIPS 2025poster

Data assimilation (DA) aims to estimate the full state of a dynamical system by combining partial and noisy observations with a prior model forecast, commonly referred to as the background. In atmospheric applications, this problem is fundamentally ill-posed due to the sparsity of observations relat…
