Extending Dynamic World Surface Water Mapping to Sentinel-1 with AlphaEarth Embeddings

Rohit Mukherjee, Frederick Policelli, Beth Tellman et al. · 2026

Dynamic World (DW) maps land use and land cover globally at 10 m from Sentinel-2 (S2) imagery, but only for cloud-free observations, which limits where and when surface water can be mapped. We use the DW water class as weak supervision for a Sentinel-1 (S1) synthetic aperture radar (SAR) model so that DW-like water map …

Benchmarking Generative Models for Near-Surface Data Assimilation on Real Station Observations

Ruizhe Huang, Qidong Yang, Jonathan Giezendanner et al. · 2026

Weather reanalysis products rely on computationally intensive numerical weather predictions followed by data assimilation that corrects the forecast toward observations. Recent advances in deep generative models offer a cheaper alternative that shifts much of this cost from inference to offline training. However, exist …
