*************************** ** THE GEM MESSENGER ** *************************** Volume 11, Number 2 January 29, 2001 -------------------------------------------------------------- 1. Minutes of GEM Steering Committee Meeting December 14, 2000 -------------------------------------------------------------- From: Frank Toffoletto The GEM Steering Committee met on Thurs, Dec 14 at 7 PM at the SF Marriot following mini-workshop sessions that afternoon. M. Hudson presided, introduced members of the steering committee and took the following minutes. Bob Robinson from NSF gave a report on the proposal response to the Oct AO. A total of 54 proposals were received, 41 for the MI Coupling Initiative supported jointly by CEDAR and 13 for the other GEM campaigns. Proposals have been sent out for review and a quick response is encouraged. A panel will be convened, but it is unlikely that this will occur before the Mag position is filled. Applications have been received for this position, and either a permanent or rotator choice is possible. There was no sense that the Oct 15 deadline, which is historical and goes back to the Global Change Initiative, should be changed. It simply takes a long time to log in and process proposals, and Robinson did not have a sense that the process was being help up by lack of a Mag program director. Howard Singer reported for NOAA that Space Weather Week will again be held this year in Boulder, the week of May 4, and described a join NASA/NOAA effort in the area of data assimilation modelled after the meteorology community efforts in this area. Michael Hesse reported for NASA that Living With a Star has been funded by Congress at the level of $20M in '01, with $150M in '02 and $180M in '03 projected. A Science Architecture Team has been designated, chaired by Glen Mason to develop the science strategy for LWS. A NASA Space Science Update was planned for December 21 on the Bastille Day event. An AO is expected for Magnetospheric Multiscale Mission in '01. Finally, a Senior Review will be undertaken in the spring of '01 organized by subject rather than mission. Hudson inquired about a Guest Investigator Program for Cluster, but Hesse had nothing specific to report outside the usual NRA process. Bill Lotko reported for MI Coupling that he and Brian Anderson organized a special session for Fall AGU on this topic, and he encouraged other working groups to take advantage of the AGU special session venue. Lotko and Anderson are co-chairs of one working group on electrodynamics of MI coupling, and Peterson and Moore the working group on ionospheric outflow. George Siscoe reported for the GGCM working group that a set of metrics have been developed but not yet released. Progress was made at the GGCM Steering Committee Meeting earlier in the day to define a Grand Challenge for comparing models against data for fixed solar wind conditions, and a report to the GEM community on the choice of events to study (3) will be forthcoming. Anthony Chan reported for the Inner Magnetosphere and Storms campaign that seven topics were discussed for the next Snowmass meeting, including tutorial ideas, and this campaign in full swing plans to occupy 2 - 2.5 days at the June meeting. Larry Lyons reports that the Tail Substorm campaign is planning nine sessions for the June meeting. A session jointly sponsored by MI coupling is planned, likewise a Steady Magnetosphere Convection session jointly with Storms. Dave Murr from BU reported as the student representative to the GEM Steering Committee that tutorials are again planned for the June workshop. A tutorial at the Intro to Space Physics level would be appropriate, perhaps on the GGCM. Hudson noted that the student tutorials will be on Sat in '01 because of the joint GEM/SHINE workshop on Sun June 17, see below. Therese Moretto reported from the European side that Oersted 2 is in the works and that Cluster 2 is a success. First results will be presented at the EGS meeting in April. Cluster does not have the same kind of open data policy as ISTP, in response to inquiry by the committee. Rick Sydora reported support from the Canadian Space Agency for small payloads and international collaborations relevant to space weather and space environment monitoring. The CSA coordinates research done by universities as opposed to taking charge of initiating programs in the manner done by NASA. He referred the committee to the web site http://www.phys.ucalgary.ca for further information. Finally, Hudson discussed plans for the June meeting, which will follow the template of this past year's meeting, with the significant addition of joint session possibilities with SHINE. The results of more recent discussions with members of the SHINE Steering Committee are contained in notes below which summarize this first opportunity to have our meetings co-located. It has been decided that there will be a joint session on Sun June 17, and a joint working group session on Wed afternoon dealing with reconnection in CMEs and substorms, the latter to be organized by Crooker and Birn. The Sunday joint workshop will deal with interplanetary structures and particles and their relative geoeffectiveness. The banquet will be planned jointly for Wed evening, while the Sun night reception is TBD whether joint or separate since SHINE will have its business meeting just prior. It will not be possible to plan anything jointly with CEDAR this year because they are meeting the same week in Longmont. However, we hope to have some CEDAR participants at the MI Coupling sessions, and some coordination is needed in scheduling, not as a joint activity, but to maximize possible attendance. Our joint GEM/CEDAR regulars on the steering committee (Greenwald and Smith) were not able to make this steering committee meeting. ------------------------------------------------------- 2. Summary of Joint SHINE/GEM Telecon Held Jan 15, 2001 ------------------------------------------------------- From: Vic Pizzo, Chair SHINE Steering Committee This is a summary of the telecon held Jan 15 concerning the joint SHINE/GEM session to be held as part of the Snowmass workshop this June. It also includes the results of a follow-up discussion held between M K Hudson, C Russell, and V Pizzo on Jan 16. The telecon participants were: D Webb, P Riley, J Luhmann, F Toffoletto, J Gurman, N Crooker, M K Hudson, C Russell, V Pizzo, Jon Linker The first decision was to have the joint session occur on Sunday, June 17, with the topic being the relation between various kinds of large scale solar/IP disturbances and the corresponding magnetospheric responses. Three main topic areas will be covered: energetic particles CIRs CMEs and magnetic clouds Each will be treated from both solar/heliospheric and geomagnetic perspectives. That is, there would be a balance of presentations from the SHINE and GEM sides for each topic area. The joint session will begin at 10am in the Cabaret Room, with a 1230-130pm break for lunch. The second half of the session will be 130-400pm. There will be a break until the commencement of the respective SHINE (600pm?) and GEM receptions (700pm?), which will be held separately but in proximity. Each of the three topical areas will be organized by one SHINE and one GEM representative. The organizers are not precluded from giving presentations, and they may either act as session chairs or choose others to do so. The preliminary plan for the topical discussions is as follows: 1) Energetic particles Organizers: A Chan (GEM); TBD (SHINE) Talks: (1) Solar overview (Kahler??) (2) Role of shocks in generating energetic particles on approach of disturbances to Earth (Reames??) (3) Killer electrons (Friedel??) (4) Protons in geomagnetic environment (Blake??Fennell??) Need to incorporate discussion of modeling efforts/status in these talks 2) CIRs Organizers: C T Russell (GEM); TBD (SHINE) Talks: (1) Solar/IP overview: origin, IP dynamics, relation to transients, solar-cycle evolution (Pizzo??) (2) Magnetospheric response (P Obrien??) 3) CMEs/clouds Organizers: M K Hudson (GEM); TBD (SHINE) [Webb??; Riley??] Talks: (1) MHD Global CME models and IP propagation (Linker/Odstrcil??) (2) MHD Global models of CME/cloud/magnetosphere interaction (Wiltberger??) (3) CME types at Sun, relation to IP magnetic clouds (T Mulligan??) (4) Response of magnetosphere (Lepping??) These talks to emphasize IP/magnetosphere interface issues Because of the number of talks, session may have to start at 9am. Otherwise, will have to pare topic areas to fit in time 10-4 timeframe. ---------- Wednesday 1/2 day joint session for discussion of parallels between physical mechanisms of CMEs and reconnection phenomena in the magnetosphere. To be organized by N Crooker and J Birn (or poss J Raeder) Forbes as a key speaker, need to engage NRL people (Spiro, Klimchuk) ---------------- Action items: VP -- contact Kahler as organizer/speaker for particles -- contact Webb or Riley to serve as SHINE CME organizer -- get SHINE CIR organizer MKH -- contact Friedl? / Aerospace for talk (organizer) for particles -- contact Lepping for GEM CME talk CTR -- contact P Obrien for GEM CIR talk contact T Mulligan for CME talk +-------------------------------------------------------------------------+ |To add name to the mailing list or for a message to the GEM community | | please contact: editor at igpp.ucla.edu | | | |URL of GEM Home Page: http://www-ssc.igpp.ucla.edu/gem/Welcome.html | |Please update your e-mail address. | +-------------------------------------------------------------------------+
