Solar Cycle 24 Exploration, Mysteries, and Discoveries in Energetic Particle Processes of the Near-Earth Space

Session ID#: 80232

Session Description:
Winding down Solar Cycle 24 will remain in history for transforming our observational understanding of energetic particle processes in the near-Earth space with unprecedented systems observatory including the Van Allen Probes, Arase (ERG), MMS, THEMIS, Cluster, GPS, GOES, LANL-GEO magnetospheric missions supported by conjugate low-altitude measurements on spacecraft and balloons, sufficient to monitor and quantify the mechanisms that control the build up and subsequent variability of energetic particle intensities in the inner magnetosphere. Many previously unresolved questions were addressed, new particle energization and loss mechanisms discovered, and new mysteries unveiled. We invite theoretical, modeling, and data-analysis contributions that use long-term multi-mission observations towards developing systems understanding of energetic particle processes of the near-Earth space.
