Learning to Optimise FISTA‐PnP for Sparse Radar Imaging

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This work presents a plug‐and‐play (PnP) framework for sparse radar imaging that combines FISTA with reinforcement learning (RL)‐based parameter adaptation, achieving faster convergence and eliminating manual parameter tuning. Extensive experiments show the framework outperforms classical methods and recent optimisation networks, providing high‐quality

Rapid Methane Flux Estimation Combining MethaneSAT and Sentinel‐5P Observations: A Case Study of Turkmenistan

open access: yesGeophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Rapid estimation of high‐resolution (∼km), regional‐scale (∼104 km2) CH4 fluxes plays a critical role in supporting the Global Methane Pledge and guiding targeted mitigation strategies. This study presents a novel method that combines XCH4 observations from MethaneSAT and Sentinel‐5P to directly estimate CH4 fluxes without relying on chemical ...

Quantifying the Lifespan of 3D Flood Structures: Unlocking the Potential of Flood Detention Areas for Enhanced Flood Control in China

open access: yesWater Resources Research, Volume 61, Issue 11, November 2025.
Abstract The escalating frequency and magnitude of floods pose significant challenges to traditional flood control measures with fixed defense capacities, such as levees, dams, and reservoirs. Flood Detention Areas (FDAs) have been widely implemented in many countries as solutions to extreme flood events, functioning by temporarily holding excess ...
