This project is a balloon-borne experiment whose main goals include 1) a focused program of investigation of high latitude ionospheric electrodynamics (the study of the properties of electromagnetic radiation and the way in which it interacts with charged matter) using multiple long duration balloons launched in Antarctica, and 2) the investigation of the fast penetration of electric fields from the outer to the inner magnetosphere in response to external inputs. The project is cooperative with Japanese X-ray and magnetometer investigators. The bulk of the proposed effort will be focused on investigation of outstanding problems of the polar and auroral ionosphere such as the nature of polar cap convection under varying solar wind conditions, dynamics of the dayside cusp, the transient and steady state coupling of the solar wind to the magnetosphere, transient phenomena on wholly closed magnetic fields lines such as traveling convective vortices (TCVs) and those related to magnetic pulsations with periods greater than one second. Another important effort will be to investigate the rapid transmission of ionospheric and magnetospheric electric fields from higher to lower latitudes in response to variations in the interplanetary magnetic field. This project consists of the construction, integration and testing of the electric field instruments for the geophysics payloads that are planned as part of the 2002-2003 continuation of the Polar Patrol Balloon Program managed by the Japanese National Institute of Polar Research Three balloons will be flown from the Japanese Antarctic Station, while one payload will be launched from McMurdo Station.

该项目是一个气球实验，其主要目标包括：1）高纬度电离层电动力学的重点调查计划（研究电磁辐射的性质及其与带电物质相互作用的方式）使用在南极洲发射的多个长时间气球，（2）研究磁场对外界输入的响应从外磁层向内磁层的快速穿透。 该项目是与日本X射线和磁力计调查人员合作进行的。 拟议工作的大部分将侧重于调查极地和极光电离层的未决问题，如在不同太阳风条件下极帽对流的性质、昼侧尖点的动力学、太阳风与磁层的瞬态和稳态耦合、全封闭磁场线上的瞬态现象，如移动的对流涡旋（TCV）以及与周期大于一秒的磁脉动有关的那些。 另一项重要工作是调查电离层和磁层电场随行星际磁场变化而从高纬度向低纬度迅速传播的情况。该项目包括为地球物理学有效载荷建造、集成和测试电场仪器，这些有效载荷计划作为2002-2003年继续实施由日本国家极地研究所管理的极地巡逻气球方案的一部分。
