The Role of Turbulence in Ice Microphysics and Sedimentation in Arctic Mixed‐Phase Clouds: Evidence From Yearlong Observations

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Despite the recognized importance of turbulence in Arctic mixed‐phase cloud (AMPC) persistence, its effects on ice microphysics and size‐dependent sedimentation remain poorly understood. Using yearlong shipborne MOSAiC observations, we examine these processes across eddy dissipation rate (EDR) ranges.

The Overlooked Role of Alongshore Beach Non‐Uniformity in Short‐Term Shoreline Variability

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Long‐term beach monitoring and satellite‐derived shoreline products are typically validated, and shoreline models calibrated, along cross‐shore transects. Open sandy beaches, however, are rarely uniform alongshore, because crescentic megacusps migrate past fixed transects, and their effect on single‐transect records remains unquantified.

Moisture Aggregation and the Cloud Transition Zone Shape Mesoscale Aerosol Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract Mesoscale moisture aggregation and cloud organization in shallow convection have gained much attention regarding their role in Earth's energy budget and cloud feedbacks on climate. Because aerosol particles swell in humid air, mesoscale moisture patterns are expected to be accompanied by corresponding variations in aerosol optical depth (AOD).

Merging Regional Climate Models and Remote Sensing Observations to Better Estimate Mountain Snow Water Equivalent

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract Large‐scale, high‐resolution estimation of snow water equivalent (SWE) in mountainous regions remains challenging. Continental‐scale approaches, including SWE reconstruction and regional climate model (RCM) simulations, are computationally expensive at high resolutions.

Intelligent ECCM technology via cognition and agility for the airborne radar

The Journal of Engineering, 2019
The electronic counter countermeasures (ECCM) technology is crucial to the modern airborne radar. In this study, opposed to the intelligent electronic countermeasure system, an intelligent anti-jamming technology is developed, which adjusts the working ...

Oil Spill Vulnerability in the Arabian/Persian Gulf Threatens Regional Water Security and Global Energy Supply

Earth's Future, Volume 14, Issue 11, November 2026.
Abstract The Arabian/Persian Gulf contains more than half of the world's proven oil reserves and is a critical hub for global energy transport, yet it faces increasing oil spill risk from intense tanker traffic, geopolitical tensions, and clandestine oil smuggling operations.

Low-resolution Airborne Radar Aircraft Target Classification

Leida xuebao, 2014
Target classification is particularly important in modern and future airborne radar. Nowadays, most investigations of radar target classification are based on wideband radar signals, which have higher requirements for SNR and radar systems, and are ...

Remote Sensing for Operational Surveillance of Mosquito‐Borne Diseases

GeoHealth, Volume 10, Issue 11, November 2026.
Abstract Remote sensing observations have demonstrated increasing value in identifying human risk from mosquito‐borne diseases because mosquito ecology is intrinsically tied to geophysical variables measurable by satellites. Satellite‐based monitoring of environmental conditions at varying temporal and spatial scales has extended our capacity for ...

Interpreting Synthetic Aperture Radar Backscatter During Effusive Eruptions: Insights From Rift and Summit Activity at Kīlauea, Island of Hawai'i

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Synthetic aperture radar (SAR) backscatter has particular advantages for monitoring the progression of effusive eruptions. It does not rely on cloud‐free or daytime satellite acquisitions and is particularly sensitive to surface roughness and local slope changes, providing complementary information to other sensors.
