RCM-I modeling of plasma sheet access to geosynchronous orbit
Abstract
Accurate knowledge of the distribution of the plasma sheet at geosynchronous orbit is essential to the development of space weather models. Using the Rice Convection Model Inertia (RCM-I), which includes inertial effects in the RCM, this study aims to provide a comprehensive data-model comparison of the electron and proton moments and fluxes at geosynchronous orbit. Using idealized inputs, we have compared our RCM-I computed averaged variations of plasma moments and fluxes at geosynchronous. Transient mesoscale bubble injections, which contribute to the formation of the bimodal nature of plasma sheet transport, significantly alter the properties and configuration of ions and electrons around the Earth. The peak values and corresponding MLT locations of hot protons along geostationary orbit show reasonable agreement with two data-driven models that are based upon LANL Magnetospheric Plasma Analyzer (MPA) data. Furthermore, the computed average differential flux of electrons at energy levels of 40 and 75 keV agrees well with those derived from GOES-13 MAGnetospheric Electron Detector (MAGED) data.
