FG: ULF Wave Modeling, Effects, and Applications

Focus Group Leaders:

• Michael Hartinger, Virginia Tech (mdhartin@vt.edu)
• Kazue Takahashi, Applied Physics Laboratory
• Brian Kress, University of Colorado and NOAA

Focus Group term: 2016-2020

Science Questions

Our group aims to address the following broad science questions: What mechanisms excite ULF waves? How do ULF waves couple to the plasmasphere/ring current/radiation belt populations? What is the role of ULF waves in Magnetosphere-Ionosphere coupling?
