Surfzone Water Depth Estimation From Surface Flows Using a Data‐Driven and Physics‐Informed Deep Conditional Generative Model

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract A physics‐informed deep conditional generative model driven with remotely sensed surface currents is shown to estimate surfzone water depths (bathymetry). The model encodes measured flow data as latent Gaussian parameters and decodes these distributions to estimate water depths over the domain, progressively refining its predictions via a loss‐

Incorporating W‐Band Doppler Velocity Signal Simulator Into COSP2: Model Evaluation Against Ground‐Based Radar Measurement

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract A new signal simulator for Doppler velocity, derived for W‐band cloud profiling radar onboard EarthCARE, is developed and implemented into the Cloud Feedback Model Intercomparison Project Observation Simulator Package version 2 (COSP2). The simulator converts the vertical motion of hydrometeors and cumulus mass flux in global climate models ...

Advancing Near‐Real‐Time Flood Inundation Mapping in Australia

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Floods are the second‐most deadly natural hazard in Australia, following heatwaves. Monitoring flood extent and depth in near real‐time (NRT) is crucial to minimize loss of life and socio‐economic impacts. This study leverages advanced computing, data management systems, and high‐quality data, including river gauge data APIs and Australian ...

Low-resolution Airborne Radar Aircraft Target Classification

open access: yesLeida xuebao, 2014
Target classification is particularly important in modern and future airborne radar. Nowadays, most investigations of radar target classification are based on wideband radar signals, which have higher requirements for SNR and radar systems, and are ...

Comparing Snow Water Equivalent Estimations From Long Short‐Term Memory Networks and Physics‐Based Models in the Western United States

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract In snowmelt‐dominated regions like the western U.S., mountain snowpacks supply 50%–70% of the total runoff. Accurate estimation of snow water equivalent (SWE) is critical for informed management of water resources, including reservoir operations, flood risk assessments, and drought mitigation. However, the spatial variability and complexity of
