Flood Inundation Modeling Using the Surface Water Ocean Topography Mission
Water Resources Research, Volume 62, Issue 7, July 2026.Abstract Flood risk mapping requires detailed river bathymetry, yet these data are unavailable for most rivers. We propose a new algorithm to estimate river bathymetry from multitemporal observations of water height by the Surface Water and Ocean Topography (SWOT) mission.

Space Weather, Volume 24, Issue 6, June 2026.Abstract ST‐Observer is a novel proposed spatiotemporal prediction model based on dynamic system theory, which has been proven to be superior to existing models in multiple spatiotemporal prediction tasks. However, its structural design results in weak time dependent modeling capabilities and a lack of frequency dependent modeling capabilities.

Polarimetric SAR Speckle Reduction Based on Bilateral Filtering
Leida xuebao, 2014 The priority during speckle reduction in Polarimetric Synthetic Aperture Radar (Pol-SAR) data is to maintain the polarization information. For this reason, it is undesirable to separate each element of polarimetric SAR.
