The proposed research program is intended to develop advanced computer simulation tools for better understanding Earth space plasma environment and enable further advances in space-plasma science; an area in which Canadian scientists have an established tradition of excellence. The proposed research consists of two themes focusing on a) ionospheric modelling and b) spacecraft-plasma interaction modelling. In the first theme, a comprehensive three-dimensional finite element model of the ionosphere would be developed and applied to provide a detailed quantitative description of the physics of the ionosphere; a complex, nonlinear and highly variable medium. A particular attention would be given to the connection between observations made on the ground with magnetometer and radar scattering arrays, and global phenomena taking place in the magnetosphere. With the second theme, modelling spacecraft-plasma interaction would lead to the development and application of advanced computing tools capable of providing insight in basic plasma physics phenomena, and enabling the optimization of and satellites instruments.

拟议的研究方案旨在开发先进的计算机模拟工具，以便更好地了解地球空间等离子体环境，并使空间等离子体科学取得进一步进展;加拿大科学家在这一领域有着卓越的传统。拟议的研究包括两个专题，侧重于a）电离层建模和B）航天器与等离子体相互作用建模。在第一个专题中，将开发和应用电离层的全面三维有限元模型，对电离层的物理特性进行详细的定量描述;电离层是一种复杂、非线性和高度可变的介质。将特别注意用磁力计和雷达散射阵列进行的地面观测与磁层中发生的全球现象之间的联系。关于第二个主题，建立航天器与等离子体相互作用的模型将导致开发和应用先进的计算工具，这些工具能够提供对基本等离子体物理现象的深入了解，并能够优化航天器和卫星仪器。
