Vertical profile reconstruction with Pol-InSAR data of a subpolar glacier [PDF]
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007 The last decade has seen an increasing demand for accurate mapping and wide-coverage monitoring of glaciers and ice sheets in order to measure and predict their response to global climate change and their contribution to sea level rise. This in turn requires a more complete understanding of their properties including topography, accumulation rates and ...

The Devastating 2022 M6.2 Afghanistan Earthquake: Challenges, Processes, and Implications
Geophysical Research Letters, Volume 50, Issue 11, 16 June 2023., 2023 Abstract On June 21st, a Mw6.2 earthquake struck the Afghan‐Pakistan‐border‐region, situated within the India‐Asia collision. Thousand thirty‐nine deaths were reported, making the earthquake the deadliest of 2022. We investigate the event's rupture processes by combining seismological and geodetic observations, aiming to understand what made it that ...

A phase-decomposition-based polarimetric coherence optimization method
International Journal of Applied Earth Observations and Geoinformation, 2022 The interference between different scattering components in distributed scatterer (DS) makes it difficult to estimate the phase from DS. Recently, some methods based on eigenvalue decomposition (EVD) are proposed to separate scatterer components from DS,

A Simple RVoG Test for PolInSAR Data [PDF]
, 2015 In this paper, we present a simple algorithm for assessing the validity of the RVoG model for PolInSAR-based inversion techniques. This approach makes use of two important features characterizing a homogeneous random volume over a ground surface, i.e ...
