New GEM Liaison to the Republic of China ---------------------------------------------------------------------- From: David Sibeck The GEM Steering Committee welcomes Lou Lee, who will serve as Liaison to the Republic of China. ---------------------------------------------------------------------- 2. WORKSHOP REPORT: The Scientific Magnetic Mapping & Techniques Focus Group ---------------------------------------------------------------------- From: Elizabeth MacDonald , Robyn Millan , Eric Donovan The Scientific Magnetic Mapping & Techniques focus group held three lively sessions at the recent GEM. The first was dedicated to presentations of new mapping techniques. Mike Henderson presented a review of event-based modeling techniques and Chia-Lin Huang presented a comparison of different empirical models at GEO. Several others presented techniques from different perspectives ranging from DMSP & FAST to GOES & THEMIS to different modeling techniques. Long talks and discussion were the focus of the joint substorm session focusing on the late growth phase. Speakers included Toshi Nishimura, Jun Liang, Larry Lyons (for Shasha Zou) and Jian Yang. Future plans include more joint sessions focusing on mapping. The plenary session by Misha Sitnov was also very relevant and a bold reminder of considerations with using empirical field models. Questions were raised about the time resolutions and dynamics resolvable with empirical field models and also the key differences between different versions. We ended by encouraging participants to get together and propose challenges for GEM funding. Several ideas were discussed including taking a Nishimura wave-mapping event and comparing other mapping techniques, or focusing on particular ionospheric signatures and looking at their magnetospheric conjugates. As a next step we intend to gather lists of available events (from Nishimura, Ganjushkina, and others) and compare the availability of model inputs and in situ data. There seemed to be significant interest from modelers and the CCMC group which has been supporting numerous challenges lately (see ccmc.gsfc.nasa.gov/challenges). A mapping challenge presents a learning opportunity regardless of a null or positive result; however, results may be difficult to interpret and apply metrics to. Our plan for mini-GEM is to compare challenge ideas with preliminary looks at the datasets and models available and additional consideration of the format and metrics. We are also planning to begin a review paper and looking for volunteers.
