Long‐Wavelength Ionospheric Compensation of InSAR Time‐Series Based on Global Ionosphere Maps

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Uncorrected long‐wavelength contributions remain a major limitation for interpreting InSAR time‐series over large areas (>100 km). Among them, the ionosphere can impact InSAR measurements across various timescales, potentially biasing secular velocity estimates.

Peatland Surface Motion: Terminology, Measurement Approaches, Models and Insights From a Global Dataset

Ecohydrology, Volume 18, Issue 8, December 2025.
ABSTRACT The surface of peatlands is constantly in motion. While pristine mires are characterized by peat growth and reversible surface fluctuation, induced by water level fluctuations, drained peatlands show subsidence due to peat mineralization and physical compaction. Still, drained peatlands show smaller but marked short‐term surface fluctuation as

A tool for estimating ground-based InSAR acquisition characteristics prior to monitoring installation and survey and its differences from satellite InSAR [PDF]

Geoscientific Instrumentation, Methods and Data Systems
Synthetic Aperture Radar (SAR) acquisition can be performed from satellites or from the ground by means of a so-called GB-InSAR (Ground-Based Interferometry SAR), but the signal emission and the output image geometry slightly differ between the two ...

Aseismic Slip on the Ilyak Strike‐Slip Fault (Tajikistan) and Active Fault and Landslide Hazards in and Around the Tajik Basin Revealed by InSAR

Tectonics, Volume 44, Issue 12, December 2025.
Abstract The Ilyak fault in Tajikistan is an E‐W striking strike‐slip fault, which forms the northern boundary of the actively deforming Tajik Basin fold and thrust belt. Determining the activity of the Ilyak fault is important for understanding the hazard to the nearby capital city of Dushanbe, and more generally in assessing the role of lithology in ...

Soil Salinity Characterization Using Polarimetric InSAR Coherence: Case Studies in Tunisia and Morocco

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
The phenomenon of soil salinization in semi-arid regions is getting amplified and accentuated by both anthropogenic practices and climate change. Land salinization mapping and monitoring using conventional strategies are insufficient and difficult.
