The United States Magnetotelluric Array and the National Impedance Map

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.

Interferometric synthetic aperture radar atmospheric correction: Medium Resolution Imaging Spectrometer and Advanced Synthetic Aperture Radar integration [PDF]

Geophysical Research Letters, 2006
Atmospheric water vapor effects represent one of the major limitations of repeat‐pass InSAR, and limit the accuracy of deformation rates derived from InSAR. The use of contemporaneous MERIS data to correct ENVISAT ASAR measurements shows a significant reduction in water vapor effects.

To Which Extent the Surface Water Ocean Topography (SWOT) Mission Is Currently Able to Monitor Water Surface Elevation and Extent on the French Lakes?

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract This study (July 2023–December 2025) assesses the SWOT satellite's ability to measure water surface elevation (WSE) and surface water extent (SWE) over diverse French lakes. WSE estimates from SWOT were compared to in situ gauge data and conventional radar altimetry, while SWE was evaluated using the Global Water Watch (GWW) database.

Earthquake Swarms Triggered by Groundwater Extraction Near the Dead Sea Fault

Geophysical Research Letters, 2019
In 2013 and 2018, earthquake swarms with a maximum moment magnitude of 4.5 occurred ~5 km from the northern section of the Dead Sea Transform Fault. Here we show that aquifer pressure data, interferometric synthetic aperture radar surface deformation ...

Reconstructing Digital Elevation Models From Single Synthetic Aperture Radar Images

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Traditional radar‐based methods of generating topography involve complex dual‐antenna or formation‐flying satellite configurations, interferometric processing, and specialized expertise. We present an approach for reconstructing digital elevation models (DEMs) from single Synthetic Aperture Radar (SAR) images using deep learning.
