Electrodynamics of Pulsar Magnetospheres [PDF]
I review the theoretical understanding of the global structure of pulsar magnetospheres concentrating on recent progress in force-free electrodynamics and first-principles simulations of magnetospheres.

Robust Global Analysis of Mid‐Latitude Ionospheric Trough Morphology
Abstract This study characterizes the main ionospheric trough (MIT) using a newly implemented detection method applied to ground‐based Global Navigation Satellite System data. The MIT is a region of plasma depletion occurring primarily in the nighttime sub‐auroral F‐region ionosphere. Analysis is based on ground‐based ionosphere total electron content (

Abstract Internally driven ULF waves are excited in the premidnight region during the magnetic storm on 22 July 2009. The excitation of ULF waves was investigated based on the Geospace Environment Modeling System for Integrated Studies (GEMSIS) magnetosphere‐ionosphere coupled model, GOES spacecrafts, and ground magnetometers.

Modeling the Time‐Variability of the Ionospheric Electric Potential (TiVIE)
Abstract We present a statistical model of the ionospheric electric potential derived from line‐of‐sight plasma velocity measurements from the Super Dual Auroral Radar Network. Electric potential patterns are produced using an established technique that models the ionospheric electric potential as a spherical harmonic expansion.

Abstract In this study, we introduce observing system simulation experiments (OSSE) and observing system experiments (OSE) to reconstruct the near‐Earth radiation environment. This study investigates the impact of satellite measurements on different orbits and the number of spacecraft measuring the particle fluxes on the reconstruction of the radiation

MHD Simulation Study on Quasi‐Steady Dawn‐Dusk Convection Electric Field in Earth's Magnetosphere
Abstract We investigated the large‐scale, quasi‐steady magnetospheric electric field by using global magnetohydrodynamic (MHD) simulations. When a southward interplanetary magnetic field was imposed, a large‐scale, dawn‐dusk electric field appeared in the magnetosphere.

Solar Wind‐Magnetosphere Coupling Under Interim Steady Conditions
Abstract Solar wind—magnetosphere coupling is an important driver of dynamics within the magnetosphere–ionosphere–thermosphere system, traditionally modeled using coupling functions. Most coupling functions assume the interaction is one‐directional, that the solar wind conditions determine the energy that is transferred into the magnetosphere.
