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.

First Quantitative Results on the Response of Green and Red Line Dayglow Emissions to Solar Flares of Different Magnitudes

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Flares originate from the impulsive release of magnetic energy in the solar atmosphere. The rise in X‐ray flux enhances ionization/electron content in the upper atmosphere, modifying the photochemical and dynamical processes that govern the ionosphere‐thermosphere behavior.

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

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 ...

Daytime Ionospheric Density Enhancement Driven by Poleward Neutral Wind Shear Associated With Gravity Waves During the November 2025 Geomagnetic Storm

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The threefold daytime electron density increases, along with strong poleward meridional winds exceeding 200 m/s were captured by Sanya Incoherent Scatter Radar (SYISR) during the geomagnetic storm of 12 November 2025. The great ionospheric enhancements were extending to mid‐latitudes over 40° observed by total electron content (TEC) from ...

Recent Advances and Future Prospects of Rare Earth‐Modified Aqueous Zinc‐Ion Batteries

ChemElectroChem, Volume 13, Issue 8, 15 April 2026.
Aqueous zinc‐ion batteries (AZIBs) offer prominent advantages of low cost, high safety, and environmental friendliness, with broad prospects for large‐scale energy storage. However, dendrite growth, hydrogen evolution reactions, and electrode structural degradation hinder their industrialization. Rare earth elements, with unique electronic and chemical
