Temporal stability of soil moisture and radar backscatter observed by the advanced Synthetic Aperture Radar (ASAR) [PDF]

, 2008
The high spatio-temporal variability of soil moisture is the result of atmospheric forcing and redistribution processes related to terrain, soil, and vegetation characteristics.

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.

A Shape Optimization Approach for Inferring Sources of Volcano Ground Deformation

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract One of the main goals of volcano geodesy is to improve the understanding of how an increase in pressure related to magma accumulation causes ground deformation in order to evaluate volcanic unrest. The inversion methods used for this purpose rely on a parametrization of the shape of the crustal volume in which pressure changes due to magma ...

Hybrid polarimetry inverse synthetic aperture radar

IET Radar, Sonar & Navigation
The inverse synthetic aperture radar (ISAR) system exploits the movement of the target to form its high‐resolution image. Further, the multi‐polarisation acquisition in ISAR collects additional information on the target's scattering properties and ...

Observations of Coherence Changes in C‐Band SAR Linked to Snow Thermodynamics and Wind Redistribution on First‐Year Sea Ice

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We present novel observations of C‐band Synthetic Aperture Radar (SAR) coherence sensitivities and patterns for snow on first‐year sea ice (FYI) consistent with snow thermodynamics and wind redistribution. Wintertime SAR coherence and backscatter change observations of landfast FYI in Dease Strait, Nunavut, Canada are made using 12‐day repeat ...
