Role of Large‐Scale Traveling Ionospheric Disturbances in the Positive Storm Phase Observed by the Millstone Hill Radar and GNSS TEC Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract A moderate geomagnetic storm was driven by high‐speed solar wind stream on 14 March 2016. We show that large‐scale traveling ionospheric disturbances (LSTIDs) played a significant role in producing the ionospheric storm positive phase at mid‐latitudes in the North American sector.

Outer Radiation Belt Dynamics During the October 2012 Storm Revisited: Rapid Inward Radial Transport From a Dynamic Outer Boundary

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Earth's outer radiation belt electron flux is highly variable and can be enhanced by over an order of magnitude over timescales less than one day, as observed during the October 2012 storm. Previous studies of this storm (e.g., Reeves et al., 2013, https://doi.org/10.1126/science.1237743) have invoked local acceleration to explain this ...

Statistical Auroral Absorption Model Parameterized by AE Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Energetic electron precipitation, often in association with enhanced geomagnetic activity, leads to increased D‐region ionization in the auroral region causing auroral absorption. A statistical auroral absorption model is presented for high‐latitudes (poleward of 50° magnetic latitude) based on data collected from 2010 to 2019 from 13 wide ...
