Coupled Observations of Space Weather Processes in the Ionosphere and Magnetosphere

The Geospace environment surrounding Earth responds to solar forcing as a system exhibiting significant coupling among processes and regions. While local observations from the ground and in space provide details of individual processes, distributed instruments provide the system-scale viewpoint needed to monitor space weather effects and to understand the coupled processes that drive them. Radar, radio propagation, and in-situ spacecraft observations are combined to address system-scale space weather phenomena. The causes and significance of ionospheric storm enhanced density are discussed and system-scale processes involved in the energization of MeV electrons in the Earth’s radiation belts are described.
