1. GEM Workshop 2017: "ULF Wave Modeling, Effects, and Applications" Focus Group Sessions
------------------------------------------------------------
From: Michael Hartinger, Kazue Takahashi, Brian Kress (mdhartin at vt.edu)

The GEM UMEA focus group seeks to address basic science questions and modeling/observation challenges pertaining to Ultra Low Frequency (ULF) waves, working with other focus groups on areas of common interest. To request a presentation for one of the sessions at this year’s GEM meeting, please use this form by June 12: https://docs.google.com/forms/d/e/1FAIpQLScwoMFCd0KiFYupmru1X83aox9TCyajPLATKLlhp70z3fBLsg/viewform?usp=sf_link

Monday 10:30-12:15 PM – Update and plans, general discussion of ULF wave modeling and observations: We’ll present a brief overview of focus group goals and discuss ongoing HGSO coordination including the 2 May 2017 PFISR conjunction. The remainder of the session is open for presentations.

Monday 01:30-03:00 PM – How do ULF waves couple to the radiation belts and ring current?: This session is open for presentations on observations and modeling of ULF wave interactions with the radiation belt and ring current populations. Speakers are encouraged to discuss which ULF wave observations and/or modeling advances are most needed to characterize ULF wave interactions in these regions.

Monday, 03:30-05:00 PM – ULF wave modeling challenge: Joint with MMV. We’ll update on the CCMC ULF wave modeling challenge and solicit feedback on challenge events. The remainder of the session is open for presentations on ULF wave modeling. We encourage discussion using a wide range of ULF wave models, including feedback from modelers on the most useful observations to initialize simulations and for data-model comparisons.

Tuesday, 03:30-05:00 PM – Magnetosphere-Ionosphere coupling processes associated with localized disturbances caused by dayside kinetic phenomena: Joint with “Dayside Kinetic Processes…” and “Testing proposed links…” Dayside kinetic phenomena such as magnetosheath high speed jets and hot flow anomalies generate localized disturbances on the magnetopause that in turn drive a range of processes in the magnetosphere and ionosphere. For this session, we request observation and modeling presentations discussing magnetosphere-ionosphere coupling processes associated with these disturbances: field-aligned currents, ULF waves, localized auroral patches and precipitation, and other phenomena. We ask each speaker to pose a discussion question related to modeling the response to localized disturbances.
