(2) Nonlinear Plasma joint CEDAR-GEM Workshop June 27-28, Santa Fe.


From Evgeny Mishin <Evgeny.Mishin at hanscom.af.mil> and Anatoly Streltsov <anatoly.v.streltsov at dartmouth.edu>.

We would like to announce a tentative Program of the "Nonlinear Plasma Effects in Auroral/Subauroral Plasmas" workshop at the upcoming GEM-CEDAR workshop in Santa Fe on June 27-July 1, 2011.

The objective of this workshop is to make an assessment of the contribution of nonlinear plasma processes to the dynamics of the magnetosphere-ionosphere system with the emphasis on their effects on the energy transport and release in the ionosphere and magnetosphere at auroral and subauroral latitudes.

The workshop description is located at http://cedarweb.hao.ucar.edu/wiki/index.php/2011_Workshop:Nonlinear_Plasma_Effects

Sincerely,

Evgeny Mishin <Evgeny.Mishin at hanscom.af.mil> and Anatoly Streltsov <anatoly.v.streltsov at dartmouth.edu>


(3) Announcement of Ion Outflow Focus Group Sessions at the GEM/CEDAR Joint Meeting in Santa Fe, June 27 and June 29, 2011.


From Dan Welling <dwelling at lanl.gov>.

The new GEM focus group on The Ionospheric Source of Magnetospheric Plasma—Measuring, Modeling and Merging Into the GEM GGCM will hold four joint GEM/CEDAR sessions at the upcoming meeting in Santa Fe. The conveners, Rick Chappell, Bob Schunk and Dan Welling would like to invite participation from the GEM/CEDAR community for any of the following four sessions. The sessions will begin with a summary overview talk and will be followed by contributed workshop-style talks with discussion. Each session will last two hours. The topics and times of the sessions are listed below. Please contact the session chairman for each of the four sessions to be added to the agenda for the session.

See a description of the Focus Group at http://aten.igpp.ucla.edu/gemwiki/index.php/FG:_The_Ionospheric_Source_of_Magnetospheric_Plasma and a description of the 4 workshops at http://cedarweb.hao.ucar.edu/wiki/index.php/Special:CEDAR-GEM_Joint_Workshop_Proposal_List (click on workshop numbers 5-8).

June 27, 2011; 1:30-3:30pm—Measurements of Ion Outflow in the Ionosphere and Magnetosphere

The Earth’s ionosphere has been shown to be a significant contributor of plasma to different particle populations of the magnetosphere. Through a variety of energization processes, the low energy ionospheric particles are transported from low altitudes upward into the magnetosphere where they can become more energized and can help create fundamentally important regions such as the plasma sheet and ring current. This workshop will review and discuss observations of outflow in the ionosphere and magnetosphere as a stimulus for refining existing outflow models.

Session Chairman: Rick Chappell rick.chappell@vanderbilt.edu


June 27, 2011; 4:00-6:00pm—Modeling Ionospheric Outflow

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.

Session Chairman: Bob Schunk schunk@cc.usu.edu


June 29, 2011; 10:00-12:00 noon

Geospace Generalized Circulation Models (GGCMs), invaluable tools for studying the Earth’s magnetosphere, have historically neglected the ionospheric source of magnetospheric plasma. Recently, an increased recognition of the importance of this source has spurred the magnetospheric modeling community towards finding new, innovative ways to include it in the large-scale models. This workshop will examine existing merging techniques between outflow and magnetosphere models and review recent discoveries concerning the impact ionospheric outflow has on the global magnetospheric results.

Session Chairman: Dan Welling dwelling@lanl.gov


June 29, 2011; 1:30-3:30pm

The Ionospheric Source of Magnetospheric Plasma: Measuring, Modeling, and Merging into the GEM GGCM focus group (or simply Outflow MMM) is a newly developed focus group aimed toward combining research of ionospheric outflow with Geospace General Circulation Models (GGCMs). The focus group has four major goals: refine existing outflow models through data-model comparisons, merge these models into the GGCMs and examine the impact on the magnetosphere, evaluate the coupled codes through data-model comparisons, and examine feedback from the magnetosphere to the ionospheric outflow. This session will summarize the Outflow MMM sessions that have taken place throughout the GEM/CEDAR meeting and work with the GEM and CEDAR communities to plan for the future of the 5-year focus group.

Session Chairmen:

  • Rick Chappell rick.chappell@vanderbilt.edu
  • Bob Schunk schunk@cc.usu.edu
  • Dan Welling dwelling@lanl.gov


We look forward to your participation in these joint sessions.
