Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Intense Global Navigation Satellite System (GNSS) amplitude scintillations usually occur in nighttime at low latitudes due to ionospheric plasma bubble irregularities. During daytime at middle latitudes, previous studies found that the sporadic E (Es) layer could lead to GNSS amplitude scintillations, which however, is relatively weak, for ...

Seismo-ionospheric coupling correlation analysis of earthquakes in Greece, using empirical mode decomposition [PDF]
Nonlinear Processes in Geophysics, 2009 Ionospheric variability as a result of earthquake events is a confirmed phenomenon as published in various seismo-ionospheric coupling studies. Generally, ionospheric variations resulting from earthquake activity are much weaker than disturbances ...

Do Eclipse‐Induced Thermospheric TADs Originate From Above or Below?
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Solar eclipses generate significant wave activity in the Earth's upper atmosphere. The source region of eclipse‐induced Traveling Atmospheric Disturbances (TADs) in the upper thermosphere—particularly the relative contributions of gravity waves from the thermosphere itself versus the lower atmosphere—remains unknown. Using the Whole Atmosphere

Wavelet analysis of the ionospheric response at mid-latitudes during the April 200 storm using magnetograms and vTEC from GPS [PDF]
, 2013 In this work we pursue the idea of computing a parameter that allows us to estimate the local ionospheric response to a geospheric event that triggers an ionospheric storm. For that, wavelet technique has been chosen because of its ability to analyze non-

Spatiotemporal Variations in the Interplate Slip Rate Around Kodiak Island, Alaska
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Monitoring spatiotemporal variations in the interplate slip rate during the interseismic period, such as transient strain release by slow slip events (SSEs), is crucial for characterizing the physical properties of faults. We analyze 10 years of Global Navigation Satellite System (GNSS) data in the region of Kodiak Island, Alaska.

Wave‐Based Quantification of Ion Composition in the Earth's Magnetosphere‐Ionosphere‐Coupling Region
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Ion composition critically determines the basic kinetic characteristics of plasma and affects energy transmission of the magnetosphere. However, it exhibits significant variations with altitude, latitude, local time, longitude, and also with geomagnetic and solar activity.
