Observation of Daily Flood Hazard During the SWOT Cal/Val Orbit

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Flood peaks can develop and recede within a day, making them difficult to capture with satellites with multi‐day revisit intervals. Here, we exploit daily observations during the Calibration and Validation phase of the SWOT mission to examine a short‐lived flood in May 2023 along the Du Gouffre River in Canada. Despite channel widths below 100

Morphological Characteristics of Tropical Precipitation Features Producing Extreme Instantaneous Rain Rates in GPM and DYAMOND Global Storm Resolving Models

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The influence of the spatial organization of tropical convection on the production of extreme instantaneous localized tropical rain rates remains poorly constrained, both in observations and in models. Using retrievals from the Ku‐band radar onboard the GPM satellite, we identify tropical precipitation features (PFs) and quantify their ...

All‐Optical Dual‐Angle Diffractive Neural Networks for 2D Direction‐of‐Arrival Estimation

Nanophotonics, Volume 15, Issue 20, 27 October 2026.
A diffractive neural network with an integrated spatial encoder resolves the direction of an incoming terahertz signal entirely through optical propagation. After the signal passes through the cross‐shaped input and two 3D‐printed diffractive layers, two detector arrays read its two incident angles simultaneously.

Architectural Tailoring and Reinforcement Strategies for Improved Bearing Strength in Thick Carbon Fiber/Epoxy Laminates

Polymer Composites, Volume 47, Issue 20, Page 18791-18811, 20 October 2026.
Schematic overview of the investigated laminate architectures and reinforcement strategies used to evaluate their effects on the bearing performance and failure behaviour of thick carbon fibre/epoxy laminates. ABSTRACT This study provides a unified experimental comparison of 11 joint configurations in thick (7–12 mm) vacuum‐infused CFRP laminates ...

Shallow Poroelastic Hydrothermal Deformation at Changbaishan Volcano Before the 2020 Unrest Revealed by Sentinel‐1 InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ground deformation of dormant volcanoes provides critical insights into subsurface processes and potential hazards. Here we present Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (2015–2020) for Changbaishan volcano, the largest intraplate volcanic system in East Asia. We detect persistent subsidence of up to 3.5 mm/yr

Microphysics and Kinematics of a High Flash Rate Storm With a Bottom‐Heavy Charge Structure

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract An atypical thunderstorm with unusual lightning and charge structure characteristics propagated through Cordoba province, Argentina, during the austral warm season in late 2018. This storm exhibited echo tops near 10.5 km, with high lightning activity concentrated at low altitudes.
