The State of Space Weather Scientific Modeling—An Introduction

The discipline of “Space Weather” is built on the scientific foundation of solar-terrestrial physics but with a strong orientation toward applied research. Models describing the solar-terrestrial environment are therefore at the heart of this discipline, for both physical understanding of the processes involved and establishing the capability to predict the consequences of these processes. This issue of Space Science Reviews contains four topical reviews on primarily European scientific progress in understanding and modeling space weather phenomena. The four reviews deal with (i) monitoring, modeling and predicting solar weather, (ii) the radiation environment of the Earth, (iii) solar wind disturbances and their interaction with geospace, and (iv) the upper atmosphere’s response to space weather events.
