Magnetosphere-Ionosphere Dynamics: Determining the Timings of the System's Response to Changes in Upstream Driving
Session ID#: 79139
Session Description:
The primary driver behind the dynamics of the Earth’s magnetosphere-ionosphere (M-I) system is the solar wind and its embedded interplanetary magnetic field (IMF). In trying to understand the complexities the solar wind introduces into the M-I system, we must first address the various timescales involved in the system’s response to changes in upstream driving. In this session, we invite submissions that advance our understanding of the response timings for any part of the M-I system. Examples may include studies that utilize magnetospheric spacecraft (e.g. Cluster, THEMIS, MMS, Geotail, Van Allen probes), ground-based observations (e.g. SuperDARN, EISCAT, magnetometer chains), modeling, or auroral observations. We welcome submissions that relate to the response timing caused by variations in any aspect of the upstream driving, including transient events in the solar wind or changes in IMF orientation.
