Interhemispheric and longitudinal differences in the ionosphere–thermosphere coupling process during the May 2024 superstorm

Earth and Planetary Physics
Geomagnetic storm events have a strong influence on the ionosphere–thermosphere (I-T) coupling system. Analyzing the regional response process of the I-T system and its differences across the northern and southern hemispheres is an important but ...

Thermospheric Wind Response to March 2023 Storm: Largest Wind Ever Observed With a Fabry‐Perot Interferometer in Tromsø, Norway Since 2009

Space Weather
Solar cycles 24–25 were quiet until a geomagnetic storm with a Sym‐H index of −170 nT occurred in late March 2023. On March 23–24, a Fabry‐Perot interferometer (FPI; 630 nm) in Tromsø, Norway, recorded the highest thermospheric wind speed of over 500 m/s

The effects on the ionosphere of inertia in the high latitude neutral thermosphere [PDF]

High-latitude ionospheric currents, plasma temperatures, densities, and composition are all affected by the time-dependent response of the neutral thermosphere to ion drag and Joule heating through a variety of complex feedback processes. These processes

Lower thermosphere densities of N2, O and Ar under high latitude winter conditions [PDF]

Measurements of the neutral thermosphere were conducted in northern Scandinavia during the Energy Budget Campaign. These measurements included determinations of N2, O, and Ar densities using rocket-borne experiments.

Were Gravity Waves or Lamb Waves Responsible for the Large‐Scale Thermospheric Response to the Tonga Eruption?

AGU Advances
The extraordinary eruption of the Tonga volcano on 15 January 2022 lofted material to heights exceeding 50 km, marking the highest observed since the satellite era.
