The GEM Steering Committee (SC) oversees all GEM activities, except funding. The SC consists of the chair, 4 science community representatives, the senior research area coordinators (see below), the chair of the GGCMSSC, and the GEM meeting organizer (MO). These are the voting members. A quorum requires the votes (in person or via e-mail) of at least half the voting members and the chair. The chair's vote breaks a tie. Votes per e-mail are permissible and are solicited by the chair. When casting an e-mail vote the voting member should e-mail the vote to all other voting members.
The SC chair and the science community representatives are appointed by the NSF GEM program manager (PM) for a term of 3 years. Care shall be taken that the voting members cover a broad range of GEM activities and interests and that the terms are staggered to maintain corporate memory.
In addition to the voting members the SC consists of the Student Representative, the GEM communications coordinator(s), liaisons to NASA, NOAA, CEDAR and SHINE, international liaisons, and the GEM program manager.
The GEM meeting organizer (MO) shall keep minutes of the each SC meeting. The minutes, excluding sensitive matters, shall be published in the GEM newsletter in a timely manner.
GGCM Science Steering Committee
The GGCM Science Steering Committee (GGCMSSC, GC) oversees the GGCM related activities. It consists of the chair and at least 5 regular members. The chair and the members are appointed by the PM for 3 year terms. The terms should be staggered to provide corporate memory. Each major modeling group, each research area, and the CCMC should be represented on the GC. The PM, the MO, and the SC chair are ex-officio members.
The GC oversees the GGCM focus groups (FGs, see below). These FGs operate and are time limited like any other focus group. The GC should initiate new GGCM FGs if the need arises.
The GC takes part in overseeing all FGs, in collaboration with the research area coordinators. The GC's specific task is to assure that the FGs work towards GGCM goals. Each FG reports at the end of its term to the GC.
The GC suggests GGCM tutorial speakers for the summer WS.
Research Area Coordinators
The Research Area Coordinators oversee the Focus Groups. Each research area has 2 Research Area Coordinators, who serve a staggered 6 year term. The senior coordinator of each research area is also a voting member of the SC. The coordinators oversee the FGs and invite tutorial speakers suggested by the FGs (see below). At present there are 4 research areas. However, the SC may change this arrangement:
· Dayside, including boundary layers and plasma/energy entry.
· Inner magnetosphere and storms.
· Tail, including plasma sheet and substorms.
· Magnetosphere - ionosphere coupling, aurora.
The SC suggests Research Area Coordinators which are appointed by the PM.
A new student representative (SR) is elected by the students every year and serves a two year term, overlapping with the term of the previous SR. The SR organizes and runs the student sessions, i.e., talks and tutorials given by students for students, on the day preceding the summer workshop. (S)he reports to the SC on the student activities. The SR from the previous year advises the currently active SR.
Focus Groups (FG) are at the heart of GEM. FGs are proposed by the community. The proposal shall be brief, no more than 2 pages, and must include:
· A description of the topic.
· A description of how the FG would relate to existing FGs.
· A specific goal, that includes a deliverable. Deliverables can be GGCM modules, empirical relations that lead to modules, solutions to specific science problems, challenges, data sets for validation and metrics, or paper collections.
· The names of the co-chairs.
· The term, not more than 5 years.
· Expected activities, for example topics of WG sessions or challenges.
Focus Groups run for no longer than 5 years. The FG co-chairs are expected to organize sessions at the summer workshop, and, if appropriate, also at the pre-AGU fall workshop. There is no set number of sessions that a FG should organize, but 2-3 sessions is considered to be typical.
The SC issues a call for FG proposals in early Fall of each year. The SC discusses the proposal and votes at its Fall AGU meeting which FGs to implement. The target number of active FGs at any time is ~12. Thus, there will be ~2-3 new FGs selected every year.
During its last year a FG writes a report to the GC that briefly outlines its activities, accomplishments, GGCM contributions, and resulting publications. This report is published in the GEM newsletter and also becomes part of the GEM 5-year report.
Summer Workshop Plenary Tutorials
The student representative, the GGCMSSC, and the FG chairs suggest speakers for the plenary tutorials at the summer workshop. The area coordinators, together with the GGCMSSC chair, decide on the invitees.
The Communications Coordinator
The communication's coordinator provides the communication infrastructure for the GEM effort through the following activities:
Issues the electronic GEM Messenger containing short news items pertinent to the affairs of GEM. These include working group reports, meeting announcements, calls for participation and similar messages. Requires maintaining an up-to-date mailing list, allowing those listed to remove themselves from list, and maintaining the security of that list so that it is not used by those not associated with GEM or copied by them. This is a mediated newsletter under the active control of an editor who must be fully engaged 365 days a year.
Issues the electronic GEMstone containing an annual report on the status of the GEM project, centered on the activities at the annual (summer) meeting. Issued at least once per year, usually no more than twice. Paper copies are available. Uses the GEM Messenger mailing list. This newsletter requires the active collection of information in contrast to the GEM Messenger that responds to member requests for issuance.
Maintains the GEM webpage describing the organization, providing access to GEM documents, allowing the posting of tutorial presentations and working group presentations as requested. Allows virtual poster sessions for those not being able to attend GEM although this has not been used much recently. Provides the historical archive of GEM activities.
Provides access to data, mainly groundbased magnetometer data, in support of campaigns and general community research. Provides support for campaigns by providing a home for data sets used for joint study. However, as individual groups become more adept and have greater storage capacity themselves, this has become less necessary.
Leads the preparation of the seven-year report whenever it is requested. This has happened only once thus far.
The coordinators are selected and funded by peer reviewed proposals to NSF.
The current MIC campaign, as of 2006, remains a traditional campaign until it closes out. As long as the MIC exists there should not be any FGs that are mainly concerned with MIC issues. For as long as the MIC campaign exists its coordinators take the role of campaign co-chairs. The MIC campaign decides for itself if it wants to close out all WGs at one time or in a staggered fashion.
The GI campaign is dissolved. Its working groups (4), and the GGCM WGs become focus groups. These FGs should write up a "proposal" that guides their activities in the coming years.
The terms in the following begin after the summer workshop of the first year and end with the summer workshop of the last year.

Issues for the 2006 Fall AGU SC meeting:
· pick new FGs
· determine remaining period and closeout for existing FGs
· since the MIC campaign plans major restructuring independent of a change to FGs we may as well end the MIC campaign now and just keep the FGs.
