Abstract The Madden–Julian Oscillation (MJO), a recurring intraseasonal (30–96 days) disturbance in the troposphere, strongly influences the E‐region and F‐region ionosphere through its modulation of atmospheric tides. Among these, the diurnal eastward wave number 3 (DE3) tide, driven by MJO‐modulated latent heating, carries MJO signals upward into the

Temporal Variability of Saturn's H2 Dayglow and Northern Aurora Observed by Hisaki and Cassini
Abstract Ultraviolet (UV) emissions from molecular hydrogen in Saturn's atmosphere consist of bright auroral emission over the poles and disk‐wide airglow. The dayside disk emits substantial intensities (dayglow) previously detected by various instruments.

Abstract We present the first comprehensive multi‐instrument climatological study of quiet‐time equatorial F‐region vertical plasma drifts across South America, a region where the magnetic declination angle varies significantly. Our analysis of well‐established long‐term ground‐based data sets from the Jicamarca incoherent scatter radar spanning 1968 ...

Jupiter's Auroral Ionosphere: Hybrid Monte Carlo, Auroral Spectrum and Conductivity Modeling
Abstract We present a new model of auroral precipitation and associated phenomena at Jupiter, called the Jupiter Auroral Ionosphere Code (JAIC). The hybrid model follows the primary electron population using a Monte Carlo code that runs on a GPU, and computes the contribution of the secondaries using a two‐stream approximation.

Abstract A balloon borne Fabry Perot interferometer called High altitude Interferometer WIND observation (HIWIND) flew from Wanaka, New Zealand (44.69S, 169.14E) in April 2025 to observe mid‐latitude thermospheric winds in the southern hemisphere for the first time.

Reinvestigating the Nightside Ionosphere of Mars With 8 Years of Mars Express and MAVEN Data
Abstract Tailward ion escape in the nightside magnetotail is one of the dominant paths of ion escape from Mars. The Martian nightside ionosphere can serve as a major reservoir for this escape channel, but its global distributions and dependence on the upstream solar wind have not been fully investigated due to observational limitations.
