The Earth's Radiation Belts, Auroral Zones, and Polar Caps: Particle Models, Event Studies, and Effects on Materials
Projects include: (1) An empirical DMSP data base of the most poleward ion precipitation boundary: The data base was analyzed statistically and analytically. At each MLT there is great variance, and the ion boundary correlates best with AE. The average boundary is a circle offset from the geomagneti...
