Topics:
Radiation belt:
1. Which solar wind drivers are most geoeffective at
radiation belt electron enhancements: high speed solar wind streams, CIRs, CMEs
including magnetic cloud and shock categories? While we may know the general
answer, we do not know in detail why some CME events, the focus of this CDAW,
are more geoeffective for electrons than others.
Sub-question: How important is pre-conditioning of the
magnetosphere? e.g.
elapsed time since previous storm, plasma sheet density, etc.? WG1 & 4 overlap.
2. What solar drivers/solar wind conditions lead to electron
flux enhancements as well as losses, esp. the deep dropouts (to L2 or so) that appear associated with large storms. What are the processes
responsible for each?
3. What are solar wind conditions leading to cutoff
reduction and trapping of Solar Energetic Particles, and solar wind plus
magnetospheric conditions leading to loss? Examples are Nov. 6 and Nov. 24 2001
SEP trapping events of > 12 MeV protons (and heavy ions) in the electron
slot region L=2.5 - 3, and sudden loss Nov. 20 2003. WG1 overlap.
Ring current:
4. What is the relative importance of the solar-wind driven
enhanced magnetospheric convection electric field, variations in the plasma sheet
population, and the penetration electric field (SAPs) on storm-time ring
current development? WG1 & WG3
overlap.
