The QUAKES‐I Stereoimaging Instrument for Measuring Surface Topography and Land Surface Processes

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract QUAKES‐I is a stereoimaging instrument for recovering surface topography to study land surface properties and processes. The instrument consists of an 8‐camera array with four cameras pointing forward and four pointing aft. Overlapped imaging during a flight‐line enables reconstruction of topography.

A fast and accurate basis pursuit denoising algorithm with application to super-resolving tomographic SAR [PDF]

, 2018
$L_1$ regularization is used for finding sparse solutions to an underdetermined linear system. As sparse signals are widely expected in remote sensing, this type of regularization scheme and its extensions have been widely employed in many remote sensing

The “Analogs for VENus' GEologically Recent Surfaces” (AVENGERS) Initiative: Using Terrestrial Analogs to Study Recent Volcano‐Tectonic Activity on Venus and Inform the Characterization of Terrestrial Exoplanets

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Several missions to Venus have recently been selected for launch, opening a new era for the exploration of the planet. A key question these missions seek to address is whether Venus is geologically active today. Detecting active volcanism on Venus would contribute to a better understanding of volcanic and atmospheric processes on Earth.

Quantifying the Effects of Volcanic Snow Cover on InSAR Coherence Using a Computationally Inexpensive Neural Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Interferometric Synthetic Aperture Radar (InSAR) measurements constrain ground movement across volcanic systems where the signal coherence remains high enough to retrieve quality phase information. A common phenomenon that degrades this coherence at volcanoes is snow cover.

Satellite Requirements to Capture Water Propagation in Earth's Rivers

Reviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract The water in Earth's rivers propagates as waves through space and time across hydrographic networks. A detailed understanding of river dynamics globally is essential for achieving accurate knowledge of surface water storage and fluxes to support water resources management and water‐related disaster forecasting and mitigation.
