Detection of Landslide‐Generated Tsunami by Shipborne GNSS Precise Point Positioning
Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Precise point positioning (PPP) of ships using Global Navigation Satellite System (GNSS) data reveals the precise movements of marine vessels. This method may quantify anomalies in sea surface height with implications for oceanographic monitoring, exploration, and tsunami warning. The GNSS PPP data from the R/V Sikuliaq, a research ship of the

Association of Relativistic Electron Microbursts Duration With Chorus Wave Properties
Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Relativistic electron microbursts are correlated with resonant scattering by whistler‐mode chorus waves. Here, we use chorus wave properties obtained from Van Allen Probe A to calculate the duration of relativistic microbursts. A detailed quantitative comparison between observed and calculated microburst durations shows consistent ranges and ...

A Generation Mechanism of Banded Plasmaspheric Hiss
Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract As a unique structure of plasmaspheric hiss emissions, banded hiss waves generally consist of an upper band above ∼200 Hz, a lower band below ∼100 Hz and a power gap in between. However, the generation mechanism of banded hiss remains unclear.

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Upcoming imaging missions—NASA's LEXI and ESA/CAS's SMILE—will target solar wind charge exchange X‐ray (SWCX) emission from Earth's magnetosheath. This emission is generated by highly charged ions colliding with neutrals in Earth's exosphere.

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Mars lacks an intrinsic dipolar magnetic field but possesses strong crustal magnetic fields scattered across its surface. There has been an ongoing debate about how these crustal fields influence the bow shock, the outermost plasma boundary of the Martian space environment.

Two‐Day Wave Modulation of Gravity Wave Momentum Fluxes Observed Over South America
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 8, 28 April 2025.Abstract Planetary wave (PW) modulation of gravity wave (GW) dissipation has long been proposed as a source of longitudinal variability in the mesosphere and lower thermosphere. However, direct measurements of GW drag are rare. We identify 2‐day wave variations in GW momentum fluxes measured by the Southern Argentina Agile Meteor Radar (SAAMER) in Rio ...
