Wave propagation and earth satellite radio emission studies [PDF]
Radio propagation studies of the ionosphere using satellite radio beacons are described. The ionosphere is known as a dispersive, inhomogeneous, irregular and sometimes even nonlinear medium. After traversing through the ionosphere the radio signal bears

A Shape Optimization Approach for Inferring Sources of Volcano Ground Deformation
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract One of the main goals of volcano geodesy is to improve the understanding of how an increase in pressure related to magma accumulation causes ground deformation in order to evaluate volcanic unrest. The inversion methods used for this purpose rely on a parametrization of the shape of the crustal volume in which pressure changes due to magma ...

Quasi‐Trapped Zebra Stripes: Radial Transport Driven by Dual‐Pulse Electric Fields
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Energetic electron spectra in Earth's inner radiation belt often exhibit regular stripe‐like features, known as “zebra stripes,” which are typically attributed to the drift motion of stably‐trapped electrons disturbed by electric field perturbations.

Positive and negative ionospheric disturbances prior to the 2016 christmas earthquake in Chile
Geomatics, Natural Hazards & Risk, 2019 Global ionospheric maps (GIMs) provided by the Center for Orbit Determination in Europe (CODE) served to analyze ionospheric disturbances prior to the December 25, 2016 earthquake in Chile.

The measurement of ionospheric absorption using extraterrestrial radio waves [PDF]
, 1957 Introduction: The discovery by Jansky in 1932 of the presence of radio waves incident upon the earth from outer space has led to several new methods of studying the earth's upper atmosphere.

Sudden Ionospheric Disturbances Generated by Solar Flares—Not so Sudden?
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract It is known that solar flares generate instantaneous ionization enhancement, referred to as sudden ionospheric disturbance (SID), that occurs simultaneously across the entire dayside. In this work, we use high‐rate 1‐s data of total electron content (TEC) to analyse ionospheric response to 13 solar flares that occurred in 2003–2023.

Do Migrating Semidiurnal Tidal Winds From the Lower Atmosphere Control Thermospheric Winds?
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Lower atmospheric tides are important for driving the thermospheric and ionospheric structure. The effects of different lower atmospheric migrating semidiurnal tidal fields of neutral density, temperature, and winds on the thermospheric winds are investigated by using the global ionosphere‐thermosphere model with forcing of the tides at the ...
