Why Do We Need to Know the Spectral Properties of Electromagnetic Ion Cyclotron Waves?

We will discuss the recent progress in understanding of ElectroMagnetic Ion Cyclotron (EMIC) waves formation mechanisms in the inner magnetosphere. This problem remains unsettled in spite of many years of experimental and theoretical studies. Modern satellite observations by CRRES, Polar and Cluster still do not reveal the whole picture experimentally since they do not stay long enough in the generation region to give a full account of all the spatio-temporal structure of EMIC waves. The following topics that relate to EMIC waves physics and it formation on a global scale would be discussed during this talk:
Why do we need to model EMIC waves?
What EMIC wave data show?
How to model EMIC wave spectral properties?
Why do we need self-consistent Ring Current and EMIC waves model?
What is new in our global EMIC waves simulation studies?
