Pathways of Dynamic Magnetosphere Coupling to High-Latitude Ionosphere

Session ID#: 75140

Session Description:
Magnetosphere-ionosphere (MI) coupling is one of the most important science topics for the near-Earth environment and space weather. Recent observational findings indicate that the MI coupling is inherently dynamic and occurs at multiple spatial scales. Understanding magnetospheric coupling to different ionospheric regions calls for innovative theoretical approaches and combined analysis of multiple datasets. We will re-examine the roles of possible coupling pathways (large and mesoscale fields, particles and ULF waves). How are these coupling mechanisms incorporated in drivers of physics-based models? What are the effects of coupling at different ionospheric altitudes and regions? How to quantify energy transport? How various precipitating particle populations contribute to local ionospheric conductivity? What is the role of ULF waves in MI coupling at different altitudes? What is the impact of the ionospheric feedback instability? Discussions of multi-instrument observations, including satellite conjunctions, ISR, SuperDARN, magnetometer chains, rocket measurements, and of modeling efforts are solicited.
