Assessing Mountain Soil Water Storage and Release in a Colombian Páramo With APSIS‐InSAR Data
Hydrological Processes, Volume 39, Issue 7, July 2025.InSAR detects seasonal soil swelling across a páramo ridge. Ridges swell during the wet season and lower valleys swell in the dry season. Findings indicate flow in the wet season is rapid from ridges through steep slopes and out of the catchment, whereas in the dry season lower valley sediments swell from a cumulative slower flow.

Water Resources Research, Volume 61, Issue 3, March 2025.Abstract Population growth, climate change, and a lack of infrastructure have contributed to an increase in water demand and groundwater exploitation in urban and rural Afghanistan, resulting in significant ground subsidence. Based on a 7‐year‐long Sentinel‐1 radar‐interferometric time‐series (2015–2022), we assess country‐wide subsidence rates.

Building profile reconstruction using TerraSAR-X data time-series and tomographic techniques [PDF]
, 2015 This work aims to show the potentialities of SAR Tomography (TomoSAR) techniques for the 3-D characterization (height, reflectivity, time stability) of built-up areas using data acquired by the satellite sensor TerraSAR-X.

Water Resources Research, Volume 61, Issue 2, February 2025.Abstract Monitoring and estimating mountain snowpack mass over regional scales is still a challenge because of the inadequacy of observational networks in capturing spatiotemporal variability, and limitations in remotely sensed retrievals. Recent work using C‐band synthetic aperture radar (SAR) backscatter data from the Sentinel‐1 satellite mission has

Earth and Space Science, Volume 12, Issue 1, January 2025.Abstract In response to the 2017 Decadal Survey, NASA conducted a five‐year study on the Surface Deformation and Change (SDC) designated observable to study potential mission concepts. As part of the SDC mission study, the Commercial Synthetic Aperture Radar (ComSAR) subgroup was tasked with evaluating the current landscape of the SAR and ...

Reviews of Geophysics, Volume 62, Issue 4, December 2024.Abstract Asian megadeltas, specifically the Ganges‐Brahmaputra‐Meghna, Irrawaddy, Chao Phraya, Mekong, and Red River deltas host half of the world's deltaic population and are vital for Asian countries' ecosystems and food production. These deltas are extremely vulnerable to global change. Accelerating relative sea‐level rise, combined with rapid socio‐

The Potential of Hydrogeodesy to Address Water‐Related and Sustainability Challenges
Water Resources Research, Volume 60, Issue 11, November 2024.Abstract Increasing climatic and human pressures are changing the world's water resources and hydrological processes at unprecedented rates. Understanding these changes requires comprehensive monitoring of water resources. Hydrogeodesy, the science that measures the Earth's solid and aquatic surfaces, gravity field, and their changes over time ...
