This project will combine data from the DMSP and NOAA polar orbiting spacecraft from 1984 - 1997 to develop and compute indices representing magnetotail stretching, the open/closed boundary location and shape, and the enclosed open magnetic flux. Automated techniques based on neural nets will be used to process the vast amounts of data to develop a database containing information on the magnetospheric state. This will enable statistical and prediciton filter studies as well as provide general availability of the indices for community use. The investigators will utilize the database for correlation and prediction filter studies.

该项目将结合DMSP和NOAA极地轨道航天器1984-1997年的数据，制定和计算代表磁尾伸展、开放/封闭边界位置和形状以及封闭开放磁通量的指数。将使用基于神经网络的自动化技术来处理海量数据，以开发一个包含磁层状态信息的数据库。这将使统计和预测筛选研究成为可能，并提供供社区使用的普遍指数。调查人员将利用该数据库进行相关性和预测过滤器研究。
