Target Superresolution Reconstruction Approach for Bistatic Airborne Radar Based on Joint Convolution Echo Model

Remote Sensing
Bistatic airborne radar is widely studied because of its separated geometric configuration, offering flexible imaging ability for its receiver. However, when the bistatic platforms work in a synthetic aperture radar (SAR) mode, the bistatic system should

AI‐Powered GPR Characterization of Peatland Underground Cavity Induced by Smoldering Wildfire: A Laboratory Proof‐of‐Concept

Safety Science and Technology, EarlyView.
We present an AI‐assisted ground‐penetrating radar framework to noninvasively detect and quantify smoldering wildfire‐induced subsurface cavities in peatlands. A ResNet model accurately predicts cavity geometry from GPR images, enabling improved assessment of underground fire damage and hazards.

Fracture and Calving Front Evolution: A Case Study of Fimbul Ice Shelf, Antarctica

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT This study combines historical records, satellite remote sensing data, and inverse modelling to investigate crack formation and calving front evolution of the Fimbul Ice Shelf, Antarctica. Historical maps from the 1950s, together with satellite imagery from 1970s–2026, are used to reconstruct calving‐front positions and track the evolution of ...

A Super‐Resolution Model for Enhancing the Intensity and Structure of Tropical Cyclone Predictions

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 6, December 2026.
Abstract Accurate predictions of intensity and structure of tropical cyclones (TCs) are crucial for disaster warning, prevention and mitigation. Traditional dynamical models with coarse horizontal resolutions suffer from systematic underprediction of TC intensity, whereas those with fine horizontal resolutions require intensive computations.

Vertical Velocity Deduced From Ice Change in MesoNHforC2OMODO RASTA‐km, a Data Set of Deep Convection Simulations Assessed Against Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 22, 28 November 2026.
Abstract Measuring vertical velocity is crucial for improving our understanding of deep convection. The Convective Core Observations through MicrOwave Derivatives in the trOpics (C2OMODO) mission aims to retrieve vertical velocity using ice‐sensitive microwave measurements acquired at two closely spaced time intervals.

Aircraft Icing: In‐Cloud Measurements and Explicit Prediction of Supercooled Large Droplets in Icing Clouds of Eastern China Using Multi‐Moment Microphysics Schemes

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract The characteristics of supercooled liquid water (SLW) within icing clouds over eastern China are investigated using in situ aircraft observations and numerical simulations. Supercooled liquid water content increases from 0 to −4°C, but decreases sharply below −4°C.
