GEM Focus Group on Magnetic Mapping
----------------------------------------------------------------------
From: Eric Donovan <edonovan at ucalgary.ca>,
      Robyn Millan <Robyn.Millan at dartmouth.edu>, and 
      Elizabeth MacDonald <macdonald at lanl.gov>

Magnetic mapping between different geospace regions is of critical 
importance to many of the GEM science challenges. Present 
observational programs produce simultaneous observations from 
disparate geospace regions that cannot be properly interpreted without 
addressing the mapping issue. Global models and simulations imply 
mappings that need to be correct in order for the models to be as 
useful as possible for science and prediction. Techniques for such 
mappings include empirical and event-based models, simulations, 
utilizing auroral boundaries and phenomena, magnetoseismology, and 
multi-point in situ particle observations. There is a pressing need 
for taking stock of these techniques, assessing their weaknesses and 
adding to their strengths, and for determining how global simulations 
compare with reality in terms of mapping. Although much work is being 
done on specific mapping techniques, this Focus Group will bring 
together scientists from different subdisciplines in an effort to 
foster an open discussion about the issues encountered when using 
these techniques, and to promote cross-fertilization of ideas. 
 
This is the first year of the GEM Focus Group (FG) on Magnetic Mapping. 
This focus group has a five year term, and aims to deliver a review of 
existing mapping techniques, new metrics for assessing the validity of 
different techniques, quantifiable improvements of existing techniques, 
and provide, through community challenges, demonstrations of how those 
improvements will benefit GGCM, activities of other focus groups, and 
GEM in general. 
 
We are holding three sessions at the upcoming GEM/CEDAR Workshop in 
Santa Fe:  
Thursday,  June 30 (13:30-15:30 and 16:00-18:00) in CC 
Coronado/DeVargas: 
 
- Overview of FG objectives 
 
- Invited talks on mapping techniques/issues (E. Zesta, J. Bortnik, V. 
Merkin) 
 
- Open discussion and solicited ~5 minute presentations 
 
Friday,  July 1 (10:15-12:15) in CC Coronado/DeVargas 
 
- Planning for future and ongoing activities 
 
In this first Workshop for the FG, we are reserving roughly half of 
overall session time for open vigorous discussions, but we still have 
time available for shorter (<5 min) talks (we have two such requests 
to date). If you are interested in presenting, please contact us (the 
organizers): Robyn Millan, Elizabeth MacDonald, and Eric Donovan 
(Robyn.Millan at dartmouth.edu, macdonald at lanl.gov, edonovan at 
ucalgary.ca).
