Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.Abstract Sea surface wind retrieval under extreme weather conditions is constrained by the sparse and irregular spatiotemporal sampling of Global Navigation Satellite System Reflectometry (GNSS‐R). This study presents a probabilistic wind field reconstruction framework for the Western North Pacific using Score‐Based Data Assimilation (SDA). A diffusion

Comparison of SAR and CYGNSS Surface Water Extent Metrics
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Many sensors are suitable for accurate delineation of open water extent, but in vegetated environments, the vegetation canopy can obscure the presence of standing water from detection. Detecting inundation extent in these vegetated environments is especially critical for identifying flooding extent where surface water may exceed flood boundaries and ...
