Three-dimensional structure of the seismo-electromagnetic ionospheric electron density disturbances [PDF]
Proceedings of the MSTU, Vol. 15, No. 3, 2012, pp.595-603, 2012 The paper presents the three-dimensional structure of the ionospheric electron density disturbances triggered by the vertical electric currents flowing between the Earth and ionosphere over the faults before the strong earthquakes. The results were obtained using the global numerical Earth's Upper Atmosphere Model (UAM).

Guide for Conducting “Community Challenges” in Space Physics
Earth and Space Science, Volume 12, Issue 5, May 2025.Abstract The Geospace Environment Modeling (GEM) program regularly issues “community challenges” in which researchers examine a particular space physics phenomenon or geomagnetic activity event, often running numerical models to assess dominant processes and understand the timing and relationship of observed signatures.

2-D model of the global ionospheric conductor connected with the magnetospheric conductors [PDF]
arXiv, 2018 A model of the ionospheric global conductor is designed. The ionospheric conductor is considered in the framework of a two-dimensional approximation based on high conductivity in the direction of the magnetic field. Under this assumption the magnetic field lines are equipotential, and the charge transfer between them is determined only by integral ...
