This research program will continue the PI's efforts to develop nonlinear, data based models for predicting geomagnetic activity. The new work will expand the previous methods to include arrays of ground-based magnetometers rather than just using various magnetic indices. The spatial resolution provided by magnetometer arrays will provide information of the propagation of disturbances and should yield new insight into the possible triggering mechanisms for substorms. It will also be possible to monitor and predict important physical quantities, such as the ionospheric electric field and Joule heating.

该研究计划将继续PI的努力，开发非线性，基于数据的模型，用于预测地磁活动。 这项新工作将扩展以前的方法，包括地面磁力计阵列，而不仅仅是使用各种磁性指数。 磁力计阵列提供的空间分辨率将提供扰动传播的信息，并应使人们对亚暴的可能触发机制有新的认识。 还将有可能监测和预测电离层电场和焦耳加热等重要物理量。
