Relative Contributions of Lower‐Atmosphere Tidal and Solar‐Magnetospheric Forcings to the Day‐to‐Day Variability of F‐Region Electron Density

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract We use Thermosphere Ionosphere Electrodynamics General Circulation Model simulations nudged to realistic tides and their statistical day‐to‐day variabilities (DTDVs), derived from Michelson Interferometer for Global High‐Resolution Thermospheric Imaging/Ionospheric Connection Explorer observations, to estimate the relative importance of tidal ...

Detection of Equatorial Plasma Bubbles Using the COSMIC‐2 Rate of TEC Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Equatorial plasma bubbles (EPBs) are large‐scale plasma depletion structures that can disrupt Global Navigation Satellite Systems (GNSS) and other space‐based technologies. Several instruments have been employed to study EPB dynamics, with Total Electron Content (TEC) and Rate of TEC change Index (ROTI) data standing out as valuable parameters

A High‐Efficiency Multivariable TEC‐SOFTS Model for Ionospheric TEC Prediction: Validation Over China Area During Low and High Solar Activity Periods

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The ionospheric Total Electron Content (TEC) is a key parameter for characterizing the ionospheric properties. In this study, an efficient multivariable time series prediction model, TEC‐Series Core Fusion and efficient multivariable time series (TEC‐SOFTS), was constructed by combining multiple geomagnetic and solar activity indices ...

Introducing Reflected GNSS TEC Data Into ANCHOR Ionospheric Data Assimilation Model

Space Weather, Volume 24, Issue 5, May 2026.
Abstract ANCHOR is a novel data assimilation (DA) algorithm developed at the U.S. Naval Research Laboratory to improve ionospheric nowcasting by increasing accuracy and decreasing computational cost. As a parameterized DA model, ANCHOR represents the ionosphere using physical parameters such as the F2 layer peak (Nm $Nm$F2), which characterizes a ...
