Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT Scaling geological CO2 storage requires simultaneously controlling plume migration, pressure buildup, geomechanical integrity, and monitoring cost under deep subsurface uncertainty. Yet early‐stage assessments often treat these elements in isolation, obscuring the decision‐critical couplings between pressure‐defined regulatory exposure and ...

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis
Laser &Photonics Reviews, EarlyView.We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Image-Domain Discrimination of Real Ship Targets and Azimuth-Ambiguity Ghosts in Maritime SAR Images
IEEE AccessAzimuth ambiguities in maritime synthetic aperture radar (SAR) images can generate ghost-like responses near strong ship scatterers, thereby increasing false alarms and degrading ship-target interpretation and automatic target recognition.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Using S‐band dual‐polarization radar and disdrometers during PRECIP 2022 in Taiwan, we analyze a Mei‐Yu frontal event with widespread stratiform rain and embedded convection. Multiple disdrometers are used to create a novel drop size distribution model for S‐band radars resolving both the drizzle and precipitation modes. The model reveals both inferred

Spatiotemporal Ambiguity-Driven System Parameter Design Method for Moon-Based SAR
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingMoon-based synthetic aperture radar (SAR) offers a vantage point for continuous, hemispheric-scale Earth observation. However, existing research primarily focuses on individual performance metrics or geometric coverage, lacking an effective system design

SHIP DETECTION USING SENTINEL-1 SAR DATA [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 The Earth’s surface is covered with 72% water. This fact alone emphasizes the importance of proper monitoring and regulation of maritime activities.

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study evaluates the subseasonal predictive skill of tropical–extratropical cloud bands across four subtropical convergence zones in ECMWF reforecasts (2003–2022). Results show that, while exact daily predictions are limited to one week, accounting for temporal displacement improves forecast skill significantly, revealing a systematic early onset ...

Small Methods, EarlyView.Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.
