Abstract Oblique slow rifting in a hotspot setting has created a distributed volcanic zone in the central part of the Azores but it's unclear what causes focusing of magma upflow under the islands within a wide plate boundary deformation zone. For São Jorge Island, we use a three‐dimensional finite element model to evaluate crustal stress from the ...

Current Development in Airborne Repeat-pass Interferometric Synthetic Aperture Radar
Due to its agility, flexibility and accuracy, airborne repeat-pass Interferometric Synthetic Aperture Radar (InSAR) is capable of overcoming the disadvantages of long revisit time and low resolution in space-borne SAR interferometry, and play an ...

Abstract The efficacy of rapid seismic response is fundamentally constrained by the sequential, multi‐step nature of conventional InSAR processing, where error propagation and reliance on auxiliary data hinder automation. Here, we present a holistic framework using Physics‐Aware Generative Adversarial Networks (GANs) to directly retrieve absolute ...

Assessment of SWOT for Monitoring Ice‐Marginal Lake Water Levels in Greenland
Abstract The Surface Water and Ocean Topography (SWOT) satellite mission provides a powerful data set for monitoring global surface water resources. However, its performance for monitoring ice‐marginal lakes in Greenland remains unknown. Due to the scarcity of in situ measurements, this study evaluated the reliability of ice‐marginal lake elevations ...

Quantifying Temporal Decorrelation over Boreal Forest at L- and P-band [PDF]
Temporal decorrelation is probably the most critical factor towards a successful implementation of Pol-InSAR parameter inversion techniques in terms of repeat-pass InSAR scenarios. In this paper the effect and impact of temporal decorrelation at L- and P-
