Space Weather, Volume 23, Issue 9, September 2025.Abstract Large‐scale traveling ionospheric disturbances (LSTIDs) are wave‐like structures propagating through the ionosphere from auroral to lower latitudes, affecting radar‐based technologies and satellite navigation. Due to their disruptive effects, timely detection is crucial. This work presents an autonomous detection technique based on travel‐time

Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.Abstract A solar eclipse leads to a local decrease in ionospheric density that generally follows the solar obscuration function, whereas the density recovery phase is often characteristically prolonged after the eclipse ended. By using simultaneous measurements of the European Incoherent Scatter Scientific Association incoherent radar and GNSS during ...

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract After less than 14 years from the previous 2011–2012 unrest, the Santorini volcano entered a new unrest phase, involving intra‐caldera deformation since July 2024 and microseismicity mainly after mid‐September 2024. We examine the first phase of this unrest, identified by GNSS and Synthetic Aperture Radar Interferometry data as an almost ...

Identification of the spatial position of permanent GPS stations in the Baltic region
Aviation, 2012 Since the last decade of the 20th century, data on repeated measurements from the Global Positioning System (hereinafter referred to as GPS) have been commonly used globally to investigate the motion of the Earth's crust. With the use of data on repeated

Space Weather, Volume 23, Issue 4, April 2025.Abstract The space weather event on 10–11 May 2024 was a high‐impact geomagnetic storm, resulting in a SYM‐H index decrease to −518 nT, the lowest level registered in several decades. We investigated the response of the Earth's ionosphere during the main phase of this storm using a comprehensive data set of ionospheric observations (in situ plasma ...

New Insights on the Crustal Deformation in the Eastern Betics From Densified GNSS Data
Tectonics, Volume 44, Issue 2, February 2025.Abstract The Eastern Betic cordillera, southeastern Spain, is characterized by slow tectonic deformation rates and moderate seismicity. Great uncertainties persist regarding the precise kinematics of the main fault system within the region, the Eastern Betic Shear Zone (EBSZ). We present a new GNSS (Global Navigation Satellite System) velocity field in

Space Weather, Volume 23, Issue 1, January 2025.Abstract Two solar flares accompanied by coronal mass ejections (CMEs) occurred on 24–25 February (DOY 055–056), 2023, resulting in a large magnetic storm on DOY 058. We reconstructed the ionospheric electron density (IED) in Europe to analyze the spatial distribution of ionosphere and its temporal evolution during this period. Computerized ionospheric

The threshold contrast thickness evaluated with different CDMAM phantoms and software
Nukleonika, 2016 The image quality in digital mammography is described by specifying the thickness and diameter of disks with threshold visibility. The European Commission recommends the CDMAM phantom as a tool to evaluate threshold contrast visibility in digital ...
