An event study to provide validation of TING and CMIT geomagnetic middle-latitude electron densities at the F2 peak [PDF]
, 2008 [1] The coupled thermosphere-ionosphere magnetosphere (CMIT) model and the Thermosphere Ionosphere Nested Grid (TING) model have been run to simulate the 15 May 1997 interplanetary coronal mass ejection\u27s (ICME) effects on the Earth\u27s ionosphere ...

On the Strength of Solar Forcing in the Earth's Thermosphere
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract We report the signature of solar forcing in the thermosphere using daytime temperature profiles from the Michelson Interferometer for Global High‐resolution Thermospheric Imaging (MIGHTI) instrument on NASA's Ionospheric Connection (ICON) Explorer mission.

Evolution of Magnetospheric Boundary Layers Under the 10 May 2024 ICME Impact
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract On 10 May 2024, an interplanetary coronal mass ejection‐driven shock impacted the dayside magnetopause, compressing it to ∼5 RE. A northward interplanetary magnetic field suppressed dayside reconnection and allowed a clear investigation of the magnetosphere response.

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Based on high‐resolution measurements from NASA's Magnetospheric Multiscale mission (MMS), we present the first direct observation of an ion diffusion region (IDR) with high number density O+ ions within dayside magnetopause reconnection during the May 2024 superstorm. The O+ ion density reaches a high value of ∼3.3 cm−3.

Observations of Ion Density and Temperature around the International Space Station During two Geomagnetic Storms [PDF]
, 2018 The International Space Station (ISS) is a low Earth orbit research facility and host to an international crew. Geomagnetic storms cause changes in the Earth’s magnetic field and affect the ion density and temperature in the ionosphere which could pose a

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Plasmaspheric plume hiss plays a crucial role in shaping Earth's electron radiation belts and influencing magnetosphere–ionosphere energy coupling. However, its generation mechanism remains contested between cyclic‐linear and localized‐nonlinear models. By analyzing over 64,000 high‐resolution plume hiss wave segments from the Van Allen Probes
