The Geospace Environment Modeling Grand Challenge: Results from a Global Geospace Circulation Model [PDF]
Journal of Geophysical Research: Space Physics, 1998 We have used our Global Geospace Circulation Model (GGCM) to simulate two time intervals that were proposed as the Geospace Environment Modeling (GEM) Grand Challenge for modelers to investigate to what extent and accuracy models can predict the ionosphere's response to the solar wind and interplanetary magnetic field.

Physics of geospace storms [PDF]
Kosmìčna nauka ì tehnologìâ, 2021 A review of our knowledge about the coupling of solar-terrestrial processes, manifestations of geospace storms, and variations in space weather is presented. Space weather effects are analyzed within the system paradigm concept. The system where geospace storms occur is a Sun–interplanetary medium–magnetosphere–ionosphere–atmosphere–Earth (interior ...

Methods for characterising microphysical processes in plasmas [PDF]
, 2013 Advanced spectral and statistical data analysis techniques have greatly contributed to shaping our understanding of microphysical processes in plasmas. We review some of the main techniques that allow for characterising fluctuation phenomena in geospace ...

Vestnik SSUGT (Siberian State University of Geosystems and Technologies), 2021 One of the important tasks of safe operation of pipeline systems is information support of produc-tion units. The purpose of this work was to determine approaches to the formation of geoinformation space to ensure the operation of complex man-made complexes of pipeline systems.

Multiphysics simulations of collisionless plasmas [PDF]
, 2018 Collisionless plasmas, mostly present in astrophysical and space environments, often require a kinetic treatment as given by the Vlasov equation. Unfortunately, the six-dimensional Vlasov equation can only be solved on very small parts of the considered ...

Dagik: A Data-Showcase System for the Geospace
Data Science Journal, 2009 We propose to establish "#data-showcase" system to display the various geophysical data in one frame. Data-showcase is a system not to provide data but to show various types of the geophysical data in intuitable way.
