Space Weather, Volume 24, Issue 10, October 2026.Abstract Space weather events can significantly alter the ionospheric electron density, affecting signal transmission and navigation accuracy in satellite‐based systems. Consequently, there is an urgent need for reliable forecasting of the Thermosphere‐Ionosphere (TI) system.

Acoustic Wave Signatures of Earthquake Rupture Dynamics in the Upper Atmosphere
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract We perform three‐dimensional coupled earthquake‐atmosphere numerical simulations that integrate dynamic rupture, seismic wave propagation, and a compressible nonlinear atmospheric model to investigate how earthquake source parameters influence acoustic wave (AW) characteristics at 100–300 km altitude in the thermosphere.

Radio Science, Volume 61, Issue 9, September 2026.Abstract Trans‐ionospheric high frequency (HF: 3–30 MHz) response to atmospheric gravity waves (GWs) is studied in the middle‐latitude ionosphere in relation to thunderstorm activity. SuperDARN HF radar observations are compared against the model simulations to quantify the impact of GW‐generated medium‐scale traveling ionospheric disturbances (MSTID ...

On the Origin of Summer Sporadic E Periodicities at Midlatitudes
Space Weather, Volume 24, Issue 9, September 2026.Abstract Summertime midlatitude sporadic E (Es) layers exhibit daily periodicities whose underlying physical causes remain to be fully identified. We investigate the origin of these periodicities by analyzing an 11‐year data set (2007–2017) comprising ionosonde measurements, FORMOSAT‐3/COSMIC radio occultation (RO) observations, and WACCM‐X neutral ...
