This grant supports an investigation of the solar wind with the terrestrial magnetosphere using ground-based magnetic records from the turn of the century to the present in conjunction with interplanetary measurements when available. This study will examine the control by the interplanetary magnetic field of geomagnetic activity, the response of the magnetosphere to the blockage of the solar wind by comet Halley in 1910; the response of the magnetosphere to rapid reductions of the momentum flux in the solar wind, the deceleration of interplanetary shocks near 1 AU, the statistical properties of geomagnetic storms and the quantification of substorm magnitudes. The study will employ the collections of the World Data Center A including those on their newly produce CDROM and the data collected during the International Magnetospheric Study (IMS). In addition to aiding our understanding of the coupling of the solar wind and the Earth's magnetosphere, and its variation over the last century, this study will help test the accuracy of the CDROM and IMS data sets and aid in the correction of those data.

这笔赠款支持使用世纪之交至今的地面磁记录并结合可用的行星际测量来研究太阳风与地球磁层。 这项研究将考察行星际磁场对地磁活动的控制，以及磁层对1910年哈雷彗星阻挡太阳风的反应；磁层对太阳风动量通量快速减少的响应、接近 1 个天文单位的行星际激波减速、地磁暴的统计特性以及亚暴震级的量化。 该研究将采用世界数据中心 A 的收藏，包括其新制作的 CDROM 上的收藏以及国际磁层研究 (IMS) 期间收集的数据。 除了帮助我们了解太阳风和地球磁层的耦合及其在上个世纪的变化之外，这项研究还将有助于测试 CDROM 和 IMS 数据集的准确性并帮助校正这些数据。
