When Thunderstorms Reach the Stratosphere: Why Storm Structure May Matter for Climate

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Deep convection that overshoots the tropopause provides one of the fastest pathways for exchanging air between the troposphere and the stratosphere. Using extensive in situ observations from the dynamics and chemistry of the summer stratosphere (DCOTSS) campaign, Shepherd et al.

Modeling the Amplitude Distribution of Radar Sea Clutter

Remote Sensing, 2019
Ship detection in the maritime domain is best performed with radar due to its ability to surveil wide areas and operate in almost any weather condition or time of day.

QUALITY ASSESSMENT OF AN EXTENDED INTERFEROMETRIC RADAR DATA PROCESSING APPROACH [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Radar data acquisition is a reliable technology to provide base data for topographical mapping. Its flexibility and weather independency makes radar data more attractive in comparison with traditional airborne data acquisition.

Improved Tropical Cyclone Wind Estimation Using Dual‐Polarization C‐Band SAR and Machine Learning

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Tropical cyclones (TCs) characterized by extreme wind speeds present severe hazards to human life and infrastructure. Spaceborne synthetic aperture radar (SAR) has emerged as a critical observational tool for TCs, owing to its all‐weather, high‐resolution imaging capabilities.

Refinement of a Framework for Moving Aircraft River Velocimetry (MARV) and Application to Particle Tracking Along Alaskan Rivers

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Information on river velocities enhances understanding flood hazards, evaluating habitat conditions, and predicting the transport of floating materials. In this follow‐up study, we used data from two new sites, one with a more complex morphology and the other with a lower suspended sediment concentration, to provide further evidence that ...

A Decade of Airborne Electromagnetic Surveying Lake Menindee (Australia) Under Varying Water Levels

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Time domain airborne electromagnetic (AEM) surveying is a mature geophysical tool for imaging the Earth's shallow subsurface. It produces images of the electromagnetic conductivity structure of the earth, down to depths of a few hundred metres.

Segmentation of Oil Spills on Side-Looking Airborne Radar Imagery with Autoencoders

Sensors, 2018
In this work, we use deep neural autoencoders to segment oil spills from Side-Looking Airborne Radar (SLAR) imagery. Synthetic Aperture Radar (SAR) has been much exploited for ocean surface monitoring, especially for oil pollution detection, but few ...

Rapid Land Surface Uplift and Groundwater Recovery Observed During the Syrian War

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Recent geopolitical upheaval in Syria is driving regional growth by returning populations, which increases demands on water resources. In northwest Syria, widespread cropland abandonment during the Syrian War starting in 2011 drastically changed the hydrological regime of the region.

Using high‐resolution imagery to map Scots pine regeneration in the Scottish uplands

Ecological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
This study utilizes high‐resolution imagery to map over 90,000 naturally regenerating Scots pines across a 3360‐ha area in the Scottish Uplands. Our approach demonstrates that remote sensing can accurately quantify landscape‐scale forest expansion, identifying nearly 85% of saplings over 2 m tall.
