中文摘要
分布在地球表面的区域性或全球性磁变计记录的数据主要有三种应用。它们是:a)固体地球的大规模区域或全球感应研究,b)日地物理研究,以及c)外部瞬态源场监测。这项资助的重点是在描述固体地球的区域化全球感应研究中的第一个应用。这项研究将制作一个动画视频,展示两类对电磁感应研究很重要的瞬态磁扰动,分别是在数小时到数天的时间内,在平静期太阳变化和风暴期磁变化。
英文摘要
There are three principal applications for data recorded by magnetic variometers regionally or globally distributed over the Earth's suface. These are: a) large scale regional or global induction studies of the solid earth, b) solar-terrestrial physics studies, and c) monitoring of external transient source fields. This grant focusses on the first application in describing a regionalized global induction study of the solid earth. This research will produce an animated video of two classes of transient magnetic disturbances important to electromagnetic induction studies at periods of hours to days, quiet time solar variations, and storm time magnetic variations.
