Interpretive Studies of Ionospheric Composition and Electrodynamics

广泛的现场和地面数据数据库用于描述电离层中电动力学和等离子体组成的各种特征。这一建议描述了一种努力，借助简单而复杂的计算机模型来解释观测现象，这些模型包含了特定现象的一些基本物理原理。将预测的行为和观察到的行为进行比较，可以作为物理描述是否充分的指标，并证实我们对该现象的理解。该方法将研究以下特征：电场映射的尺度依赖性及其对电场、电流和粒子降水之间预期关系的影响。底侧f区风浪对大尺度发电机场和小尺度中间等离子体层产生的影响。随演化时间变化的电离层对大的亚极光离子漂移的响应。*** //

An extensive data base of on-site and ground based data is used to describe various features of the electrodynamics and plasma composition in the ionosphere. This proposal describes an effort to interpret observational phenomenon with the aid of simple and sophisticated computer models containing some of the basic physics of a particular phenomenon. Comparison of the predicted and observed behavior is used as an indicator of the adequacy of the physical description and as a confirmation of our understanding of the phenomenon. The following features will be studied with this approach: The scale-size dependency of electric field mapping and its effects on the expected relationship between field and currents and particle precipitation. The effects of winds and waves in the bottomside F-region on the generation of large scale dynamo fields and smaller scale intermediate plasma layers. The response of the ionosphere to large sub-auroral ion drifts with varying evolution times. *** //
