Studies of Magnetospheric ULF Waves Using Active Magnetospheric Particle Tracer Explorers Charge Composition Explorer

Abstract

Recent studies of ULF pulsations in the inner magnetosphere (L < 6.6) with the Active Magnetospheric Particle Tracer Explorers Charge Composition Explorer are reviewed. Pulsations in the Pc 3-4 and Pi 2 bands with distinctive waveform, polarization, and spatial amplitude distribution are discussed separately. Specific pulsation types include toroidal-mode Pc 3-4 oscillations, equatorial compressional Pc 3 pulsations, Pi 2 pulsations, and giant pulsations. In addition to the highlights of published results, unresolved problems for each pulsation type are described.
