To fully understand the atmosphere of the earth and its variation due to various solar inputs requires not only data on the global variability, but also theoretical explanations and modeling in three dimensions. This program is a continuation of the development of detailed coupled models of the ionosphere and thermosphere to more deeply delve into the physical processes operating within the global system. The model is a three dimensional model of the coupled ionosphere and thermosphere that calculates the wind, temperature, geopotential and ion and neutral compositional fields between 97 and 500 km altitude on a global grid. It can be used for detailed case studies through comparisons with ground-based and space-borne experimental observations. Planned model developments include a self- consistent treatment of global electrodynamics, the coupling to the magnetosphere and a downward extension to incorporate the mesosphere.

为了充分了解地球大气及其由于各种太阳输入而引起的变化，不仅需要全球变率的数据，还需要三维的理论解释和建模。该计划是电离层和热层详细耦合模型发展的延续，以更深入地研究全球系统内运行的物理过程。该模型是电离层和热层耦合的三维模型，在全球网格上计算海拔97 - 500 km之间的风、温度、位势以及离子和中性成分场。它可以通过与地面和空间实验观测的比较，用于详细的案例研究。计划中的模式发展包括对全球电动力学的自洽处理、与磁层的耦合以及向下扩展以纳入中间层。
