Global GNSS Observation of Mesoscale Ionospheric Irregularities (2006–2024)
Abstract Mesoscale ionospheric irregularities are statistically investigated using an unprecedented 19‐year long‐term global GNSS (Global Navigation Satellite System) TEC (total electron content) data set. These irregularities are represented by ionospheric fluctuations within a 5°× ${}^{\circ}\times $ 3.75° ${}^{\circ}$ (latitude by longitude) region ...

Energy Conversion Pathways Inside Kelvin‐Helmholtz Vortices
Abstract Energy transfer, cross‐scale coupling, and dissipation in astrophysical plasmas remain fundamental unresolved problems. The velocity‐shear–driven Kelvin–Helmholtz instability (KHI), ubiquitous in plasmas, is a key multiscale mechanism enabling plasma mixing, particle energization and the solar wind–magnetosphere coupling, making it a critical ...

Bayesian Approach to Ionospheric Elementary Current Systems Using Differentiable Basis Functions
Abstract Spherical elementary current systems (SECS) have become a widely used tool to model vector fields on spherical surfaces in ionospheric data analysis. The systems were originally formulated using point sources for the divergence and curl of the fields. In this paper we present a flexible alternative formulation, showing how continuous functions

Auroral Acceleration Generates Electron Beams in Jupiter's Middle Magnetosphere
Abstract Observations made by the Juno spacecraft above Jupiter's polar regions have revealed that electrons accelerated toward Jupiter, which contribute to auroral emissions, are frequently accompanied by electrons accelerated away from Jupiter. These electrons should be observable as narrow electron beams in the middle magnetosphere, in accordance ...

Abstract From 1974 to 1975, the Mariner 10 spacecraft studied Mercury's environment during three flybys and detected hydrogen, helium, and possibly atomic oxygen in the exosphere using its ultraviolet spectrometer, but no molecular hydrogen. Based on the sensitivity of the occultation instrument, an upper limit for the H2 ${\mathrm{H}}_{2}$ surface ...
