2011 Workshop:Modeling Ionospheric Outflow
Modeling Ionospheric Outflow
Location, Date/Time and Duration
Conveners (First is CEDAR convener, Second is GEM convener, the rest are co-conveners)
Format of the Workshop
The session will begin with an invited tutorial to review the existing ion outflow models, and then workshop-style talks to determine the important ion outflow energization processes and the strengths and limitation of the existing models
Because of the overlap of interest in both the CEDAR and GEM communities, we estimate the attendance at 50 people.
Justification for the workshop
This workshop will be an important element of the new GEM Focus Group on The Ionospheric Source of Magnetospheric Plasma. It is one of a set of workshops that are being proposed for the CEDAR-GEM meeting in order to kick-off this new area of study.
Requested Specific Days
It would be helpful if this workshop could be scheduled toward the beginning of the meeting so as to fit together with the 3 other workshop elements on this topic that are being proposed. It would be optimal if it could follow the Measurements of Ion Outflow session. We also plan to propose a final workshop planning session toward the end of the week.
Special technology requests
An LCD projector compatible with laptop computers.
There is a continuous ion outflow from the Earth at high latitudes. The outflow consists of light thermal ions (H+ , He+ and O+) and energized ions (NO+, O2+, N2+, O+, N+, He+ and H+). The ion energization in the polar wind is associated with photoelectrons, hot magnetosphere electrons and ions, wave-particle interactions in the cusp and nocturnal oval at various altitudes, electromagnetic wave turbulence above the polar cap, and centrifugal acceleration. In addition, the ion outflow occurs in conjunction with magnetospheric convection, which causes the high-latitude plasma to drift into and out of the dayside ionosphere, cusp, polar cap, nocturnal auroral oval, and subauroral night-side ionosphere. Because of the complicated dynamics, various ion outflow models have been developed, including hydrodynamic (fluid), hydromagnetic, semi-kinetic, kinetic, generalized transport, and macroscopic particle-in-cell models. This workshop will identify the ionospheric outflow models that currently exist, establish the strengths and limitations of existing models, and determine the important outflow processes that need to be included in outflow models.
This is where the final summary workshop report will be.
