Impact of Two Radio Occultation Constellations on Numerical Weather Prediction: Polar‐Orbits Only and Mixed Polar‐Equatorial Orbits

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract This study explores the relative impact of two orbital configurations for Global Navigation Satellite System radio occultation (RO) observations in numerical weather prediction using observing system simulation experiments (OSSE). Three experiments are carried out: a Control experiment with no RO observations and two experiments with 14,000 RO

Schumann Resonance Frequency Increase Following Recurrent Solar Wind Stream Onsets

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Recurrent high‐speed streams and corotating interaction regions (HSS/CIRs) are common solar‐wind drivers, but their influence on Schumann resonance (SR) frequencies remains poorly quantified. We analyzed 173 threshold‐defined HSS/CIR proxy onsets using superposed epoch composites, bootstrap uncertainty, and a month‐matched random‐epoch null ...

Computer Simulation of Reconnection in Planetary Magnetospheres [PDF]

Symposium - International Astronomical Union, 1985
The earth's magnetosphere provides an ideal opportunity to model reconnection in well known geometries that are close enough to the idealized analytic models to make a comparison of the computer models with analytic theory meaningful. In addition more detailed, even three-dimensional, models can be used for a comparison with extended data from in situ ...

Coordinate Systems and Transforms in Space Physics: Terms, Definitions, Implementations, and Recommendations for Reproducibility

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract In space physics, acronyms for coordinate systems (e.g., GEI, GSM) are commonly used; however, differences in their definitions and implementations can prevent reproducibility. In this work, we compare definitions in online resources, software packages, and frequently cited journal articles and show that implementation differences can lead to ...

Direct Observations of Magnetic Reconnections at the Magnetopause of the Martian Mini‐Magnetosphere

Geophysical Research Letters
While Mars lacks a global intrinsic magnetic field, it does exhibit crustal magnetic anomalies (mostly in its Southern Hemisphere). These crustal magnetic anomalies directly interact with solar wind, which forms a mini‐magnetosphere and a region denoted ...

MHD effects of the solar wind flow around planets [PDF]

Nonlinear Processes in Geophysics, 2000
The study of the interaction of the solar wind with magnetized and unmagnetized planets forms a central topic of space research. Focussing on planetary magnetosheaths, we review some major developments in this field.

Statistical Analysis of the Equatorward UV Auroral Emissions of the Jovian Southern Hemisphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study presents a comprehensive statistical analysis of Jupiter's southern UV auroral emissions, with a focus on the secondary oval and equatorward injection signatures. Utilizing Hubble Space Telescope (HST) data, the frequency, location, and intensity of these auroral features are systematically evaluated, considering their variation ...

Current Sheet Geometry and Heavy Ion Influence on Reconnection

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract In some planetary magnetospheres singly ionized heavy ion species can be found in addition to the typical hydrogen. The presence of these ions can affect many magnetospheric processes. The role heavy ions, specifically oxygen, and the thickness of the current sheet play in magnetic reconnection is investigated using particle‐in‐cell ...

Closed magnetic topology in the Venusian magnetotail and ion escape at Venus

Nature Communications
Venus, lacking an intrinsic global dipole magnetic field, serves as a textbook example of an induced magnetosphere, formed by interplanetary magnetic fields (IMF) enveloping the planet.

Comparative studies of planetary magnetospheres

Eos, Transactions American Geophysical Union, 1992
Three recent “flyby” spacecraft encounters of planetary magnetospheres have provided new glimpses of the broad spectrum of plasma behaviors that occur within such environments. Voyager 2's encounter with Neptune in August 1989 and Galileo's grav itational assist encounters with Venus in February 1990 and Earth in December 1990 have revealed significant
