DIP - Magnetotail Dipolarization and Its Effects on the Inner Magnetosphere

Models have shown that BBFs/DFBs/Mesoscale Injections are important for both ring current and radiation belt build-up, but it remains difficult to verify with observations and therefore the exact role remains an open question. Model results are inconclusive because existing models do not describe all the relevant domains (e.g., magnetotail, transition region, inner magnetosphere) self-consistently while capturing the required range of spatiotemporal scales. We therefore ask, How is plasma and electromagnetic energy transported through the plasma sheet to the inner magnetosphere at different spatiotemporal scales?

In this session, we will discuss the perennial question, What is the role of reconnection and/or other plasma instabilities in producing elementary magnetotail dipolarizations? How do the physical properties of the dipolarizations depend on their spatial location and the time of their appearance relative to the Dungey cycle?

DIP - Magnetotail Dipolarization and Its Effects on the Inner Magnetosphere

We therefore ask, How is plasma and electromagnetic energy transported through the plasma sheet to the inner magnetosphere at different spatiotemporal scales?

Especially given the upcoming Decadal Survey, we want to use a designated session to discuss the following:

• What do we currently know from models?
• What are the limitations of the current models?
• What modeling advances are required and feasible to resolve these limitations in the near- and long-term future (e.g., 5-10 years vs 10-30 years)?
• What do we currently know from observations?
• What can we still learn from existing observations and what are their limitations that inhibit further progress?
• What new observations are required and feasible to resolve these limitations in the near- and long-term future?
