One of the important objectives of this project is to transfer from the Goddard Space Flight Center to the Kyoto University the entire data set of the Dynamics Explorer (DE) 1 and 2 magnetometer observations. The transfer of the large volume of data on the order of several gigabits requires a careful planning and coordination. The construction of database at the Kyoto University had to be made with care so that the subsequent data analyses can be conducted with high efficiency and that the system would be compatible with that at Goddard to maximize the benefit of the joint analysis effort. For investigations of the magnetosphere-ionosphere coupling processes the electric field and plasma data and auroral images are often needed in addition to the magnetic field data. In this regard, cooperation from the relevant DE Principal Investigators has been obtained. Thus far the high time resolution DE-2 magnetic and electric field data have been transferred. The transfer of the DE-1 magnetometer data is being delayed due to a delay in the data reduction at Goddard ; however, the data transfer is expected to be completed by the end of 1992. A Preparations is being made for transferring some of the plasma data in the future.For the data analysis the investigations of (a) the relationship between the magnetic field perturbations and the electric field in the field-aligned current regions and (b) the field-aligned current near the dayside cusp have been given a high priority. Other subjects investigated include, for instance : the field-aligned currents, plasma convection, and electron precipitation during periods of extreme magnetic quiescence, toroidal standing waves excited by a storm sudden commencement, and spatial relationships between region 2 field-aligned currents and electron and ion precipitation in the evening sector

该项目的重要目标之一是将动力学探测器1号和2号磁强计观测的整个数据集从戈达德航天飞行中心转移到京都大学。传输数量级为几千兆位的大量数据需要认真规划和协调。在京都大学建立数据库时必须谨慎小心，以便能够高效率地进行随后的数据分析，而且该系统将与戈达德的系统兼容，以便最大限度地发挥联合分析工作的效益。为了研究磁层-电离层耦合过程，除了磁场数据外，还需要电场和等离子体数据以及极光图像。在这方面，已获得相关DE主要研究者的合作。到目前为止，高时间分辨率的DE-2磁场和电场数据已经传输。由于戈达德数据处理工作的延迟，DE-1磁力计数据的传送被推迟;不过，数据传送预期将于1992年底完成。A正在为将来传输等离子体数据做准备。对于数据分析，（a）场向电流区的磁场扰动和电场之间的关系以及（B）向阳面尖点附近的场向电流的研究已被赋予高度优先权。研究的其他课题还包括：极端磁静止期间的场向电流、等离子体对流和电子沉淀、风暴突然开始激发的环形驻波、以及2区场向电流与傍晚扇区电子和离子沉淀之间的空间关系
