Gravity Wave Influences on MSTID Climatology Over CONUS: WACCM‐X Year‐Long Simulation and GNSS Long‐Term Observation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) are prominent wave‐like structures in the ionosphere, with complex generation mechanisms involving both atmospheric gravity waves (GWs) and electrodynamic instabilities such as the Perkins instability (PI).

Terrestrial Space Weather Protection Through Human‐Produced Mass‐Loading

Space Weather, Volume 24, Issue 6, June 2026.
Abstract While humans become more reliant on Earth's space environment, the potential for significant harm from severe space weather continues to grow. As structures from the sun reach Earth's magnetosphere and space environment, they deposit energy that fuels geomagnetic storms.

A Major Update to the PyIRI Model

Space Weather, Volume 24, Issue 6, June 2026.
Abstract This paper presents a major update to the PyIRI model, a fully vectorized Python implementation of the International Reference Ionosphere (IRI). The update reformulates the IRI core coefficients using spherical harmonics in Quasi‐Dipole (QD) latitude and Magnetic Local Time coordinates, replacing the legacy geographic‐coordinate‐based basis ...

Advancing Heliophysics and Space Weather Modeling Through Open Science

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

Nonlinear Variability in the Geomagnetic Secular Variation of the Last 150 Years

, 2002
A nonlinear forecasting analysis has been applied to the secular variation of the three-component annual means of 14 observatories, unevenly distributed over the Earth's surface (12 in the northern and 2 in the southern hemisphere) and spanning the last ...

Long‐Term Trends in the Calibration of the Cluster Fluxgate Magnetometer Instruments

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The calibration parameters of the Cluster mission's fluxgate magnetometer instruments have been determined and updated on a per‐orbit basis throughout the 24 years of the mission. Since there is no absolute field reference for vector measurements in‐flight, various spacecraft‐to‐spacecraft and instrument‐to‐instrument comparisons have been ...

An Investigation into the Use of Satellite Data to Develop a Geomagnetic Secular Variation Model over Southern Africa

Data Science Journal, 2011
There is a need to develop secular variation (SV) models using satellite data as the use of ground data is not always possible. Ground data has many limitations including limited data points and lack of data over ocean areas that are not easily ...

HIWIND Observation of Daytime Thermospheric Winds Over New Zealand and Comparison With Model Simulation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
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.
