Plasma Conditions Govern the Reversible Transition Between STEVE and Picket Fence Emissions

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract On 6 May 2018, a remarkable subauroral optical event exhibiting three phases of evolution (Strong Thermal Emission Velocity Enhancement [STEVE] → Picket Fence → STEVE) and co‐occurrence with a stable auroral red arc was observed over Alberta, Canada.

On the Energy Source of Green Emissions in Ghost

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The understanding on the formation mechanism of ghosts as a new category of transient luminous events and favorable conditions for their occurrence is limited. In this work, we examined six ground‐based observations of ghost events captured by digital SLR cameras.

Coupling Between Dispersive Alfvén Wave and Modified Electron Acoustic Wave in Downward Current Region: Parallel Potential Drop and Upgoing Ionospheric Electrons

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Results from a 1D kinetic simulation, for the first time, unveil the generation and time evolution of the downward parallel electric fields stemming from the coupling between modified electron acoustic waves (MEAWs) and dispersive Alfvén waves (DAWs).

Origin of Intense Plasma Depletions After Midnight Over the Korean Peninsula During the Geomagnetic Storm on 11 May 2024

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract A band of total electron content (TEC) depletions of about 5–15 TEC unit passed over the Korean Peninsula after midnight during the geomagnetic storm on 11 May 2024. This magnitude of TEC depletions has not been previously reported in the region.

Whipped and Mixed Warm Clouds in the Deep Sea

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Turbulence is indispensable to redistribute nutrients for all life forms larger than microbial, on land and in the ocean. Yet, the development of deep‐sea turbulence was not studied in three dimensions to date. As a disproportionate laboratory, an array of nearly 3,000 high‐resolution temperature sensors had been installed for three years on ...

Isothermal Thermoluminescence Dating of Coral Reef Calcite: Implications for Sea‐Level Change

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Reconstructing past sea‐level changes is critical in Quaternary science. On remote oceanic reefs, aragonite‐to‐calcite alteration occurs during subaerial exposure, directly recording the timing of sea‐level fall. U–Th dating of coral calcite is challenging due to open‐system issues.

Spectroscopic Fingerprinting of Coordination‐driven Spin States in Metal‐organic Architectures

open access: yesChemistry – A European Journal, Volume 32, Issue 3, 16 January 2026.
Coordination geometry controls spin states in Co‐TCNQ frameworks. Combined theory and XAS confirm the high‐spin Co2+ on graphene and establish a direct approach for spin‐state assignment in metal‐organic systems. ABSTRACT Determining the local geometry of metal‐organic architecture on substrates is challenging, as substrate interactions can alter the ...
