Auroral oval layers detection by using CSES plasma and electric field data

Ionospheric medium fluctuations are detected at various spatial and
temporal scales. Plasma irregularities encountered crossing high latitude current
systems can be extremely thin and, therefore, unlikely to identify with standard
detectors. This work aims to show plasma layer features obtained by electric field
instrument on-board the Chinese Seismo Electromagnetic Satellite while crossing
the equatorward boundary of the auroral oval allowing the characterization of its
various layer. In addition, we made the multi-scale statistical analysis in order to
describe the fluctuations of the ionospheric medium.
