On the Possibility of Driving the Electron Flux Probabilistic Models by the AE Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract We present the new probabilistic model of the electron fluxes designed to assess the risks of the spacecraft surface charging for missions with near‐equatorial orbits in the inner magnetosphere. It is a second model developed within a frame of the European Space Agency's activity “Plasma Environment Modeling in the Earth's Magnetosphere ...

Geomagnetic Disturbances Due To Neutral‐Wind‐Driven Ionospheric Currents

Space Weather
Previous simulation efforts on geomagnetic disturbances (GMDs) and geomagnetically induced currents (GICs) mostly rely on global magnetohydrodynamics models, which explicitly calculate the magnetospheric currents and carry certain assumptions about the ...

Thermospheric temperatures during geomagnetically disturbed periods.

Journal of geomagnetism and geoelectricity, 1986
Nighttime thermospheric temperatures were derived from Doppler line profiles of the [OI] 630nm emission that were observed by using a 15-cm high-resolution Fabry-Perot interferometer at a field station near Albany (42.68°N, 73.82°W), New York.The temperatures, obtained during magnetically quiet periods in May, June and July, 1978 when Kp≤2, are ...

Assessing Magnetic Fluctuations Effects in the South American Sector in Relation to Global Variations Using Ksa Index, Kp Index, and Hybrid Formats During Quiet Times Across the Seasons of the 2020 Solar Minimum

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Geomagnetic indices can be used to quantify variations in geomagnetic activity caused by Sun‐Earth interactions across the magnetosphere and ionosphere. The global Kp index is widely used as a global geomagnetic indicator, but it is based mostly on the Northern Hemisphere with no contributions from South American observatories.

Real-time ISEE data system [PDF]

, 1979
A real-time ISEE data system directed toward predicting geomagnetic substorms and storms is discussed. Such a system may allow up to 60+ minutes advance warning of magnetospheric substorms and up to 30 minute warnings of geomagnetic storms (and other ...

Statistical Characteristics of Electron Precipitation During HSS‐ and ICME‐Driven Storms Observed by the EISCAT Radar

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The 1–100 keV electron precipitation during storm time has been studied by applying the updated ELSPEC inversion method to field‐aligned electron density profiles measured by the EISCAT Tromsø radar at L = 6.5. The statistical properties of peak energy, total energy flux, and total number flux as a function of MLT have been studied for the two

Ionosphere‐Thermosphere Coupling in the Northern Polar Region During the May 2024 Geomagnetic Superstorm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The May 2024 superstorm, as the most intense geomagnetic storm since 2003, caused a variety of disturbances in the magnetosphere‐ionosphere‐thermosphere system. This study investigates the long‐lasting electron density depletion in the polar region and the underlying ionosphere‐thermosphere coupling, based on a comprehensive set of ...
