Abstract

The particle flux in the near-Earth environment can increase by orders of magnitude during geomagnetically active periods. This leads to intensification of particle precipitation into Earth's atmosphere. The process potentially further affects atmospheric chemistry and temperature. In this research, we concentrate on ring current electrons and investigate precipitation mechanisms on a time scale comparable to the cadence of satellites on low Earth orbit (LEO) using a numerical model based on the Fokker-Planck equation. We focus on investigation of the precipitation mechanisms and their connection with atmospheric parameters. In this study, we investigate a time period that covers 4 corotating interaction region (CIR) and 2 coronal mass ejection (CME) storm events. For all storms we quantify impact on the electron ring current and the resulting electron precipitation. ...
