FG: Scientific Magnetic Mapping & Techniques

Short link to this page: http://bit.ly/gem_mapping

• 2015 GEM, the final mapping sessions
  • We are having 3 final discussion-focused sessions at GEM; please join us and volunteer an update on your work or a brief perspective on the efforts of the last 5 years.
    • Tuesday at 10:30 we will begin with a Joint session: Testing Proposed Links between Mesoscale Auroral and Polar Cap Dynamics and Substorms & Scientific Magnetic Mapping & Techniques AKA “What is a streamer and how does it map?"
      • Speakers including Chao Yue '3D Substorm Growth Phase Force-Balanced Plasma and Magnetic Field Modeling Application: A Substorm Event Study', Eric Donovan, and more
    • Thursday at 10:30 (Challenge work in progress, OCB work especially welcome)
      • Speakers including Peter Porazik 'Modification of the loss cone for energetic particles', Raluca Ilie "mapping isotropic boundaries to the tail", Phil Valek "TWINS/RBSP comparison on Nov 14., 2012 storm, Liz MacDonald "OCB scenario Nov 14 2012", and more
    • Thursday at 1:30 (the final session, surveying progress and the path forward!)
      • Ideas to consider: EOS or review article, new focus group (and topics?), upcoming BARREL-SWEDEN campaign

If you would like to present something, please send a note to Liz, Eric, or Robyn. If you already sent one, it might not hurt to send it again—thanks! :)

• We would like to invite community participation in our session, by simply adding input to our survey forms on Mapping Science questions (http://bit.ly/vYuGc5) and Mapping Techniques (http://bit.ly/ucmMLQ). The survey results will be discussed at the mini-GEM and form the basis for planning of activities for the 2012 summer GEM Workshop. They will also be posted online (http://bit.ly/vPLlv9, http://bit.ly/uFw8Uz). We also welcome 1 slide presentations on specific questions or techniques if you wish. V. Papitashvili will give a brief intro to magnetic coordinate systems at the mini-GEM also.

We look forward to a productive discussion and thank you for your input in advance.
