地球观测(EO)预报旨在依据变化的天气条件,从卫星观测预测未来地表动态。本文将其建模为部分可观测、天气驱动的世界建模问题,其中天气作为条件信号,而由于观测稀疏和未观测的陆面状态,预报本身具有不确定性。然而现有方法未能完整刻画这一设定:确定性模型将不确定性坍缩为单一未来预测,而基于扩散的方法通常将天气变量视作无条(原文此句截断)。Earth Observation (EO) forecasting aims to predict future Earth surface dynamics from satellite observations under changing meteorological conditions. In this paper, we view this task as a partially observed, weather-driven world modeling problem, in which weather acts as a conditioning signal, while forecasting remains uncertain due to sparse observations and unobserved land-surface states. However, existing methods do not fully capture this setting: deterministic models collapse uncertainty into a single future prediction, while diffusion-based methods typically treat weather variables as un
