This project has two tasks. The first is to continue the analysis of data obtained from electric field and x-ray instruments flown in Antarctica in the past. The second is to provide electric field measuring instruments for long duration balloons to be flown by the Japanese from Syowa Station, Antarctica, and to analyze the resulting data. These Polar Patrol Balloons (PPB) are expected to circumnavigate the south pole several times and to have flight times of approximately one month. They will, in the course of their flights, cover geomagnetic latitudes ranging from the high polar cap to the mid-latitude ion trough. The main focus of the research will be on ultra-low frequency (ULF) waves. The proposers will perform a statistical study of the ratio of electrical to magnetic field strength as a function of frequency, geomagnetic activity, magnetic local time and magnetic latitude. These studies will provide data on the variation of geoelectric activity at different times in the solar cycle. Simultaneous coordinated measurements were made during the earlier campaign by several ground based instruments including the PACE radar, and this will also be done during the Japanese Polar Patrol Balloon flights.

这个项目有两个任务。 一是继续分析 从电场和X射线仪器获得的数据 在南极洲，在过去。 二是提供电场 测量仪器的长期气球飞行的 来自南极洲昭和站的日本人， 结果数据。 这些极地巡逻艇（PPB）预计将 环绕南极几次， 大约一个月的时间。 他们会在 它们的飞行，覆盖了从高纬度到低纬度的地磁纬度， 极冠到中纬度离子槽。 研究的主要重点将是超低频（ULF） 波 提案人将对比例进行统计研究 电磁场强度的函数 频率、地磁活动、磁地方时和磁 纬度 这些研究将提供关于 太阳活动周期中不同时期的地电活动 同时进行协调测量期间， 包括PACE在内的几个地面仪器的运动 雷达，这也将在日本极地巡逻期间完成 气球飞行
