Justification for the workshop

Critical aspects of the M-I system cannot be addressed in isolation. The CEDAR-GEM workshop is a perfect place for developing a broader understanding of the system where drivers originate in both regimes.

Requested Specific Days


Special technology requests


In the last decade, there have been many new development in understanding the electrodynamic coupling of the inner magnetosphere with the middle and low latitude I-T system. One of the great achievements was the identification and explanation of common magnetic-storm processes in plasmaspheric and ionospheric data and images, and the realization that disturbance dynamo and prompt penetration electric fields are not independent but interact with each other non-linearly. New developments continue to highlight the coupled nature of the system during quiet times as well as in response to magnetic storms. Significant gaps in our understanding still exist and lie in the need to quantify the various sources of electrodynamic variability at mid and low latitudes and the interactions and feedback between them. For instance, during quiet times, fluctuating winds in the thermosphere from sources in the lower atmosphere are likely to compete with fluctuation of magnetospheric sources, both in terms of driving winds and in imposing modest penetration electric fields. These sources of quiet-time fluctuations in the fields, render it extremely difficult to separate storm from quiet, since the background from one day to the next can be 50% of the signal. During storms the magnetospheric sources tends to dominate but lack of knowledge in the uncertainty in the quiet background can confuse interpretation of the storm response. This workshop is designed to bring together the CEDAR and GEM experts in the sources of mid and low latitude electrodynamics from the inner magnetosphere, thermospheric wind dynamo, and forcing from the lower atmosphere.
