Convection Algorithms for Magnetospheric Particles

Abstract

This report documents in detail the implementation of the convection model used for the research by Kerns, Hardy, and Gussenhoven titled 'Modelling of Convection Boundaries Seen by CRRES in 120 eV to 28 keV Particles.' This research is to be published in the Journal of Geophysical Research, Space Physics in 1993. The convection model assumes an Earth centered dipole magnetic field with equipotential field lines and a static cross tail electric field. Convection results from EXB drifts and magnetic field gradient and curvature drifts. Algorithms are provided to calculate drift paths of particles as well as to calculate the energy range of particles at a specified position that are on open drift paths to the magnetospheric tail. The algorithms presented in this document are optimized to converge to a solution quickly for any particle energy, position, and equatorial pitch angle. These algorithms are implemented in the CRRES survey software called SHOWLEPA.EXE which was used in support of the research.... Plasma sheet, Magnetospheric convection, Electron, Proton
