Backwater Effects From River Ice Jams Observed With SWOT Pixel Cloud Data
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract This study examines the backwater effects from ice jams in Arctic rivers using the Surface Water and Ocean Topography (SWOT) satellite. Ice jams occur when chunks of ice accumulate and obstruct the river flow, causing rapid water level rises and flooding.

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 ...

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 ...

Use of a portable topographic mapping millimetre wave radar at an active lava flow. [PDF]
, 2006 A ground-based millimetre wave radar, AVTIS (All-weather Volcano Topography Imaging Sensor), has been developed for topographic monitoring. The instrument is portable and capable of measurements over ranges up to ∼7 km through cloud and at night.

Engineering Reports, Volume 8, Issue 4, April 2026.The test results displayed reveal that the proposed method efficiently accomplishes the remote sensing image processing of the area, yielding a differential interferogram of the image. This interferogram accurately represents the area and provides a solid foundation for calculating the environmental hazard zone within the construction area.
