Long- and Short-Term Monitoring of a Dam in Response to Seasonal Changes and Ground Motion Loading: The Test Case of the Kurpsai Dam, Western Kyrgyz Republic
(
- Pure and Applied Geophysics
, 2021-09-22)
An experimental multi-parameter structural monitoring system has been installed on the Kurpsai dam, western Kyrgyz Republic. This system consists of equipment for seismic and strain measurements for making longer- (days, ...
Integrated Interpretation of Magnetic and ERT Data to Characterize a Landfill in the North-West of Cologne, Germany
(
- Pure and Applied Geophysics
, 2021-05-10)
Electrical resistivity tomography (ERT) and ground magnetic surveys were applied to characterize an old uncontrolled landfill in a former exploited sand and gravel quarry in an area to the north-west of the city of Cologne, ...
Performance of the International Monitoring System Seismic Network Based on Ambient Seismic Noise Measurements

All nuclear explosions are banned by the Comprehensive Nuclear-Test-Ban Treaty. In the context of the treaty a verification regime was put into place to detect, locate, and characterize nuclear explosions at any time, by ...
GNSS code and carrier phase observations of a Huawei P30 smartphone: quality assessment and centimeter-accurate positioning
(
- GPS Solutions
, 2020-04-02)
In 2016, an application programming interface was added to the Android operating systems, which enables the access of GNSS raw observations. Since then, an in-depth evaluation of the performance of smartphone GNSS chips ...
Observing Earth’s magnetic environment with the GRACE-FO mission
(

, 2021-02-15)
The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission carries magnetometers that are dedicated to enhance the satellite’s navigation. After appropriate calibration and characterisation of artificial ...
Extending access to localizer performance with vertical guidance approaches by means of an SBAS to GBAS converter
(
- GPS Solutions
, 2020-01-13)
Currently, many commercial airline aircraft cannot perform three-dimensionally guided approaches based on satellite-based augmentation systems. We propose a system to rebroadcast the correction and integrity data via a ...
Two methods to determine scale-independent GPS PCOs and GNSS-based terrestrial scale: comparison and cross-check
(
- GPS Solutions
, 2020-10-12)
The GPS satellite transmitter antenna phase center offsets (PCOs) can be estimated in a global adjustment by constraining the ground station coordinates to the current International Terrestrial Reference Frame (ITRF). ...
A ground motion logic tree for seismic hazard analysis in the stable cratonic region of Europe: regionalisation, model selection and development of a scaled backbone approach
(
- Bulletin of Earthquake Engineering
, 2020-08-29)
Regions of low seismicity present a particular challenge for probabilistic seismic hazard analysis when identifying suitable ground motion models (GMMs) and quantifying their epistemic uncertainty. The 2020 European Seismic ...
Regional climate downscaling over Europe: perspectives from the EURO-CORDEX community
(
- Regional Environmental Change
, 2020-04-23)
The European CORDEX (EURO-CORDEX) initiative is a large voluntary effort that seeks to advance regional climate and Earth system science in Europe. As part of the World Climate Research Programme (WCRP) - Coordinated ...
Deciphering the Whisper of Volcanoes: Monitoring Velocity Changes at Kamchatka's Klyuchevskoy Group With Fluctuating Noise Fields
(
- Journal of Geophysical Research: Solid Earth
, 2023-03-30)
Volcanic inflation and deflation often precede eruptions and can lead to seismic velocity changes (dv/v $dv/v$) in the subsurface. Recently, interferometry on the coda of ambient noise‐cross‐correlation functions yielded ...
