项目摘要

The terrestrial magnetosphere is created by the interaction of the Earth's internal magnetic field with the supersonic solar wind continuously streaming from the Sun. Physical processes in the near Earth space environment have tremendous effects on many aspects of modern technology. These effects include GPS accuracy, quality of high-frequency radio communications, especially at the high geographic latitudes, performance of various space assets, including numerous failures of scientific and commercial satellites. The research described in this proposal is aimed at improving our understanding of the terrestrial magnetosphere and developing research tools applicable to improving performance of space assets. The focus of our research is using advanced numerical modeling to describe and understand the physics of the near Earth space environment. To this end we will collaborate with various Canadian and International experimental space physics groups in using their data-sets to validate and improve the current generation of the global circulation models for the terrestrial magnetosphere. We will also implement additional numerical models to assess danger to satellites in space coming from high-energy electrons which often cause serious failures of satellite electronics. Various aspects of the proposed research will be used for Highly Qualified Personnel training at Master/Phd student as well as Postdoctoral levels.

地面磁层是通过地球内部磁场与超音速太阳风的相互作用而产生的，从太阳连续流出。近地球空间环境中的物理过程对现代技术的许多方面都有巨大影响。这些效果包括GP的准确性，高频无线电通信的质量，尤其是在高地理纬度，各种太空资产的性能，包括许多科学和商业卫星的失败。该提案中描述的研究旨在提高我们对陆地磁层的理解，并开发用于改善太空资产绩效的研究工具。我们研究的重点是使用先进的数值建模来描述和理解近地球空间环境的物理。为此，我们将与加拿大和国际实验太空物理小组合作，利用其数据集来验证和改善陆地磁层的全球循环模型的当前一代。我们还将实施其他数值模型，以评估来自高能电子的空间中对卫星的危险，这些卫星通常会导致卫星电子的严重故障。拟议研究的各个方面将用于硕士/博士学位学生以及博士后水平的高素质人事培训。
