    The physical properties of the multi-ion solar wind plasma and turbulent wave spectra are modeled with multifluid models, while the kinetic processes that lead to solar wind ion heating by resonant waves and instabilities are modeled with hybrid models that include the kinetic ion wave-particle interactions and ion-cyclotron wave heating. In regions of upward current, precipitating auroral electrons are accelerated earthward. These processes can result in ion outflow, changes in ionospheric conductivity, and affect the particle distributions on the field line, affecting the M-I coupling processes supporting the . We then apply the ionospheric metric described in Jordan et al. () to study the impact of ionospheric structure on MWA data, by dividing MWA EoR datasets into classes with good and poor ionospheric conditions, using sets of matched minute observations from September.

On the basis of likely sources of ion energization, comparisons suggest that (1) the efficiency of ion energization and acceleration processes vary as a function of MLT and altitude, (2) auroral zone acceleration above DMSP is relatively more important in the cusp than midnight, (3) transverse heating is relatively more important than other Cited by: 9.

The purpose of the MACCS array is to study ionospheric currents, plasma flows and waves associated with the magnetospheric cusp and neighboring regions. In association with the radar systems beginning to operate in this same area, these magnetometers will provide high resolution, two-dimensional data on the electrodynamics of cusp convection.
