GEM: Data-Based Modeling of Magnetic Storms in the Inner Magnetosphere

这个项目将继续发展磁层中地球磁场的真实模型。特别是，这项工作将针对磁暴期间内磁层的改善。还将开发一个新的指数，作为磁暴期间磁场状态参数化的机制。用于生成改进模型的数据将来自国家空间科学数据中心（NSSDC）现有的多航天器数据库。由此产生的模型将通过NSSDC向公众提供。

This project will continue the development of realistic models of the Earth's magnetic field in the magnetosphere. In particular, this effort will be directed at improvements to the inner magnetosphere during magnetic storms. A new index will also be developed as a mechanism for parameterizing the state of the magnetic field during magnetic storms. The data for generating the improved models will come from the existing multi-spacecraft database available from the National Space Science Data Center (NSSDC). The resulting models will be made publicly available through the NSSDC.
