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.

Retrieving Hourly Aerosol Absorption From Space Using Physical Informed Deep Learning
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Retrieving aerosol absorption properties, such as single scattering albedo (SSA) and absorption aerosol optical depth (AAOD) from single‐view satellite observations remains a significant challenge. This study introduces the Physics‐Informed Neural Network for Aerosols (PINA) framework to retrieve hourly aerosol absorption properties from ...

Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks
Advanced Materials, Volume 38, Issue 32, 8 June 2026.ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...
