Abstract Space weather effects arise from the dynamic conditions in the Earth's space
environment driven by processes on the Sun. While some effects are influenced neither by …

Abstract Interplanetary Coronal Mass Ejections (ICMEs), their possible shocks and sheaths,
and co-rotating interaction regions (CIRs) are the primary large-scale heliospheric structures …

Magnetic storms due to corotating interaction regions (CIRs) have been shown to elicit
different responses in the magnetosphere than those prompted by other types of solar wind …

The impact of radial diffusion in storm time radiation belt dynamics is well‐debated. In this
study we quantify the changes and variability in radial diffusion coefficients during …

This unique, authoritative book introduces and accurately depicts the current state-of-the art
in the field of space storms. Professor Koskinen, renowned expert in the field, takes the basic …

We use a three‐dimensional global magnetohydrodynamic (MHD) simulation code to
examine the energy flow from the solar wind to the magnetosphere. We simulate a major …

From 29 January to 7 February 2022, the heliosphere was structured with large-scale
interacting substructures that appeared with significant dissimilarities at distant observations …

The Daedalus mission has been proposed to the European Space Agency (ESA) in
response to the call for ideas for the Earth Observation program's 10th Earth Explorer. It was …

Heliophysics is a fast-developing scientific discipline that integrates studies of the Sun's
variability, the surrounding heliosphere, and the environment and climate of planets. The …

Thermosphere densities near 410 km altitude between±87° latitude and near 0430 and
1530 local time from the accelerometer experiment on the CHAMP satellite are used to …
