Abstract : The main objective of this research project is to study the low energy electron precipitation and auroral phenomena over polar regions. The research is based on using various types of measurements from several USAF satellites at both low altitude polar orbits and high altitude geosynchronous orbits. These are focused on: (1) to investigate the different kinds of polar electron precipitations such as various auroral displays, the polar cusp region, conjugate photoelectrons, polar rain over the polar cap; (2) to determine precipitation characteristics for various kinds of magnetospheric and geophysical phenomena; (3) to investigate the physics and configuration of the polar cusp region and the polar cap region; and (4) to understand the morphology of magnetospheric particle population. The results of these studies can lead us to a better understanding of the interaction between the solar-wind and the geomagnetic field and also the coupling between the magnetosphere and the ionosphere.
