TOWARDS INSAR EVERYWHERE, ALL THE TIME, WITH SENTINEL-1 [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Sentinel-1A was launched in April 2014, and has been collecting data routinely over more than one year. Sentinel-1B is set for launch on 22 April 2016.

First Onset of Unrest Captured at Socompa: A Recent Geodetic Survey at Central Andean Volcanoes in Northern Chile

Geophysical Research Letters, 2023
We report the first detection of unrest at Socompa volcano during our recent survey of Central Andean volcanos in Northern Chile using Interferometric Synthetic Aperture Radar measurements spanning January 2018 to October 2021.

LiCSBAS: An Open-Source InSAR Time Series Analysis Package Integrated with the LiCSAR Automated Sentinel-1 InSAR Processor

Remote Sensing, 2020
For the past five years, the 2-satellite Sentinel-1 constellation has provided abundant and useful Synthetic Aperture Radar (SAR) data, which have the potential to reveal global ground surface deformation at high spatial and temporal resolutions. However,

LiCSAR: An Automatic InSAR Tool for Measuring and Monitoring Tectonic and Volcanic Activity

Remote Sensing, 2020
Space-borne Synthetic Aperture Radar (SAR) Interferometry (InSAR) is now a key geophysical tool for surface deformation studies. The European Commission’s Sentinel-1 Constellation began acquiring data systematically in late 2014. The data, which are free

Weak Keys in the Rekeying Paradigm: Application to COMET and mixFeed

IACR Transactions on Symmetric Cryptology, 2020
In this paper, we study a group of AEAD schemes that use rekeying as a technique to increase efficiency by reducing the state size of the algorithm. We provide a unified model to study the behavior of the keys used in these schemes, called Rekey-and ...

InSAR‐Derived Horizontal Velocities in a Global Reference Frame

Geophysical Research Letters, 2023
Interferometric Synthetic Aperture Radar is used to measure deformation rates over continents to constrain tectonic processes. The resulting velocity measurements are only relative, however, due to unknown integer ambiguities introduced during ...

Lateral Variations in Lower Crustal Strength Control the Temporal Evolution of Mountain Ranges: Examples From South‐East Tibet

Geochemistry, Geophysics, Geosystems, 2021
Controversy surrounds the rheology of the continental lithosphere, and how this rheology controls the evolution and behavior of mountain ranges. In this study, we investigate the effect of lateral contrasts in the strength of the lower crust, such as ...

Nickel oxide nanoparticles exposure as a risk factor for male infertility: “In vitro” effects on porcine pre-pubertal Sertoli cells

Frontiers in Endocrinology, 2023
Lately, nickel oxide nanoparticles (NiO NPs) have been employed in different industrial and biomedical fields. Several studies have reported that NiO NPs may affect the development of reproductive organs inducing oxidative stress and, resulting in male ...

Constant strain accumulation rate between major earthquakes on the North Anatolian Fault

Nature Communications, 2018
Accumulation of interseismic strain may now be constrained by satellite observations. Here, the authors show that strain accumulation rates on the North Anatolian Fault are constant for the interseismic period indicating that lower-crustal viscosities ...
