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 ...

On the derivation of the spacetime metric from linear electrodynamics [PDF]
, 2001 In the framework of metric-free electrodynamics, we start with a {\em linear} spacetime relation between the excitation 2-form $H = ({\cal D}, {\cal H})$ and the field strength 2-form $F = ({E,B})$.

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 ...
