ULF Waves' Interaction with Cold and Thermal Particles in the Inner Magnetosphere

This thesis focuses on ULF (Ultra-low-frequency) waves' interaction with plasmasphere particles and ring current ions in the inner magnetosphere. It first reports and reveals mutual effect between ULF waves and plasmasphere using Van Allen Probes data. The differences and similarities of different ring current ions interacting with ULF waves are extensively explored using Cluster data, which provides a potential explanation for O⁺-dominated ring current during the magnetic storms.
