Title:  "Properties and Local Plasma Parameters of EMIC Waves: Recent Progress"

Abstract: Electromagnetic ion cyclotron (EMIC) waves play an important role in particle energization and losses in the Earth’s magnetosphere. This type of wave is typically excited by an anisotropic distribution of energetic (~10-100 keV) protons in a region characteristic of large total plasma density and low magnetic field strength. In the talk, I will report our recent progress in the EMIC wave studies: 1) Multiple bidirectional EMIC waves observed by Cluster at middle magnetic latitudes in the dayside magnetosphere, 2) A statistical analysis of EMIC wave properties using ten years (2001-2010) of data from Cluster, totaling 17,987 minutes of wave activity, and 3) Excitation of EMIC waves detected by the Van Allen Probes on 28 April 2013.
