Description

NASA’s dual spacecraft Van Allen probe mission was launched to increase understanding of the radiation belt environment and the role of waves in controlling radiation belt fluxes. It is particularly important to understand the conditions that lead to wave growth. In this study several intervals of electromagnetic ion cyclotron (EMIC) wave activity observed by these spacecraft were analyzed. This study will focus on understanding the role of cold plasma on the growth of EMIC waves. Specifically, I analyzed wave events in the inner magnetosphere and performed linear stability calculations of the dependence of EMIC wave stability of cold plasma populations.
