The PI plans to investigate the linear/nonlinear character of the geomagnetic variation response at high, middle and low latitudes on the changing conditions in near-Earth space, and study their global behavior within the 20-22nd solar activity cycles. Moreover, he will obtain and study the global spatial distribution of geomagnetic variations caused by the interplanetary magnetic field (IMF) and solar wind changes. Next, he will apply spherical harmonic expansions to the results and create a primary set of coefficients for the Global Geomagnetic Variation Reference Field model. Finally, this model and its global changes will be exploited on a scale of three decades for implications into the Earth's interacting physical, biological, and human system models.***

PI计划在近地空间的变化条件下调查高、中、低纬度地磁变化响应的线性/非线性特征，并研究它们在第20-22个太阳活动周期内的全球行为。此外，他还将获得并研究由行星际磁场(IMF)和太阳风变化引起的地磁变化的全球空间分布。接下来，他将对结果应用球谐展开，并为全球地磁变化参考场模型创建一组主要系数。最后，这个模型及其全球变化将在三十年的范围内被用来研究对地球相互作用的物理、生物和人类系统模型的影响。
