Call for Presentations at 2012 GEM Summer Workshop: The Scientific Magnetic Mapping and Techniques Focus Group ---------------------------------------------------------------------- From: Elizabeth MacDonald , Robyn Millan , and Eric Donovan The GEM Magnetic Mapping Focus group is pleased to announce our sessions for Snowmass 2012. * Monday at 3:30 in the Carroll room we will begin with a session focusing on a variety of mapping techniques. We will especially focus on newer techniques not discussed previously. * Tuesday at 3:30 in the Carroll room will be a joint session with the Substorms group focusing on mapping specific to the late growth phase. * Finally, Wednesday at 3:30 in the Carroll room we will brainstorm ideas for a challenge for our focus group. We will also discuss developing a review article on mapping techniques. * Also, the plenary session by Misha Sitnov (8:30 - 10 on Wednesday) is on empirical magnetic field modeling of interest to both mapping and GGCM modeling concerns. Those interested in volunteering for any of these exciting, challenging topics, please contact Liz MacDonald, Robyn Millan, and/or Eric Donovan at your earliest convenience.

Call for Presentations at 2012 GEM Summer Workshop: Measuring Models Climatologically: A new paradigm in GGCM model validation (A session of the GGCM-Metrics and Validation Focus Group) ---------------------------------------------------------------------- From: Tim Guild , Howard Singer , and Lutz Rastaetter The goal of the GGCM Metrics and Validation focus group is to provide a systematic and quantitative evaluation of different GGCM modeling approaches. To date, the majority of model validation exercises have been focused on comparing model output to short time-series of observations, such as geosynchronous magnetic field observations or Dst during a storm. This session solicits ideas and presentations devoted to non-standard methods of model validation, especially over "climatological" intervals (weeks to years). Climatological validation of a model is complementary to validating the dynamics during a storm, ensuring that the model performs well "on average". Magnetospheric simulations have recently been extended long enough to begin attempting these alternative validation methods, and the GEM community would benefit from alternative tools to comprehensively test the performance of GGCM models and understand their shortcomings. We therefore solicit ideas and short presentations (5 minutes maximum) of novel GGCM validation techniques, especially using climatological intervals on Wednesday, June 20th, between 1:30 and 3PM in the Carroll Room. We welcome ideas that stimulate participant discussion. While in the spirit of GEM we welcome people to just show up with a viewgraph or two, for organizational purposes it will help if you please email the session conveners your name and a brief title. Thank you, Tim Guild (timothy dot guild at aero dot org), Lutz Rastaetter (lutz dot rastaetter-1 at nasa dot gov) and Howard Singer (howard dot singer at noaa dot gov). ---------------------------------------------------------------------- 3. Geospace scientists: Please HELP! ---------------------------------------------------------------------- From: James Klimchuk If a joint meeting between the SPA Section and the AAS Solar Physics Division were held every third year in the spring timeframe, would you likely attend? Please send e-mail to James.A.Klimchuk@nasa.gov with "yes" or "no" in the subject line and your AGU affiliation (SA, SM, or SH) in the body of the message. Additional information can be found at http://www- ssc.igpp.ucla.edu/spa/spanews_toc.html (Issue 30, May 16). "No" answers are as valuable as "yes" answers.
