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 ...

Geophysical Research Letters, Volume 51, Issue 13, 16 July 2024.Abstract Atmospheric rivers (ARs) deliver significant and essential precipitation to the western United States (US) with consequential interannual variability. The intensity and frequency of ARs strongly influence reservoir levels, mountain snowpack, and groundwater recharge, which are key drivers of water‐resource availability and natural hazards ...

An InSAR‐GNSS Velocity Field for Iran
Geophysical Research Letters, Volume 51, Issue 10, 28 May 2024.Abstract We present average ground‐surface velocities and strain rates for the 1.7 million km2 area of Iran, from the joint inversion of InSAR‐derived displacements and GNSS data. We generate interferograms from 7 years of Sentinel‐1 radar acquisitions, correct for tropospheric noise using the GACOS system, estimate average velocities using LiCSBAS ...

Expanding the Spatial Reach and Human Impacts of Critical Zone Science
Earth's Future, Volume 12, Issue 3, March 2024.Abstract Two major barriers hinder the holistic understanding of subsurface critical zone (CZ) evolution and its impacts: (a) an inability to measure, define, and share information and (b) a societal structure that inhibits inclusivity and creativity. In contrast to the aboveground portion of the CZ, which is visible and measurable, the bottom boundary
