地球主磁场电流分布模型:离散逆理论方法

Current Distribution Models for the Earth's Main Magnetic Field: A Discrete Inverse Theory Approach

Terence V. Sewards

摘要:

采用传统的离散逆理论方法计算了地球主地磁场的电流源模型。源结构是放置在地球核心表面和地球表面的球形表面。该数据集包括MAGSAT卫星1979年进行的测量。由此产生的电流分布进行了讨论的偶极和电流回路模型。

英文摘要:

Current source models for the Earth's main geomagnetic field are calculated employing conventional discrete inverse theory methods. Source structures are spherical surfaces placed at the surface of the Earth's core, and at the surface of the Earth. The data set consists of measurements taken by the MAGSAT satellite in 1979. The resulting current distributions are discussed in relation to dipole and current loop models.
