This project will improve current models of the Earth's magnetic field at high latitudes and at larger distances from the Earth than current models. The new model will include a model of the location of the magnetopause that depends on solar wind pressure and the interplanetary magnetic field (IMF). The twisting of the cross-tail current sheet in response to the By-component of the IMF will be included in the model as will the deep depression of the magnetic field in the magnetospheric cusp due to the diamagnetic effect of magnetosheath plasma. The model will be distributed to the scientific community via the National Space Science Data Center (NSSDC) web site.

该项目将改进目前对高纬度和距离地球更远的地球磁场的模型。新的模型将包括磁层顶位置的模型，该模型取决于太阳风压力和行星际磁场(IMF)。由于磁鞘等离子体的反磁效应，磁层尖端的磁场深度降低，模型中将包括响应IMF副分量的交尾电流片的扭曲。该模型将通过国家空间科学数据中心(NSSDC)网站分发给科学界。
