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 ...

Journal of Geophysical Research: Space Physics, Volume 130, Issue 3, March 2025.Abstract Deep convective clouds and lightning activity during thunderstorms imprint Infrasonic (> ${ >} $3 mili Hertz) oscillations in the ionospheric density or Traveling Ionospheric Disturbances (TIDs). The wave characteristics of these oscillations and the coupling mechanisms remain a subject of investigation, noting that the coupling energetics may

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

Long Term Global Ionospheric Total Electron Content Trend Analysis
Geophysical Research Letters, Volume 51, Issue 21, 16 November 2024.Abstract Simulations based on physical models of the thermosphere‐ionosphere system suggest that the ionosphere will sink as the thermosphere cools and contracts in response to increasing greenhouse gas concentrations. As a consequence, long‐term trends can be expected in ionospheric parameters such as: total electron content (TEC), the critical ...

Near‐Real‐Time Identification of the Source of Ionospheric Disturbances
Journal of Geophysical Research: Space Physics, Volume 129, Issue 11, November 2024.Abstract The ionosphere is characterized by a large number of disturbances generated in response to a wide range of phenomena, including natural hazards, space weather and man‐made events. Identification of the origin of ionospheric disturbances (ID), especially in real or near‐real‐time (NRT), is an extremely difficult task, and it is one of the most ...

Space Weather, Volume 22, Issue 11, November 2024.Abstract On 10 May 2024, a severe geomagnetic storm coinciding with Mother's Day in Mexico lasted over 40 hr and produced polar auroras observable at low latitudes. This storm, the most intense since 2003, resulted from a series of solar flares and coronal mass ejections from active region 3664.
