Theoretical Studies of the Upper Atmosphere Using the NCAR Thermosphere-Ionosphere General Circulation Model

要全面了解地球大气及其在各种太阳输入下的变化，不仅需要全球变化的数据，还需要三维的理论解释和建模。该方案是开发详细的电离层和热层耦合模型的继续，以更深入地研究在全球系统内运行的物理过程。该模型是一个电离层和热层耦合的三维模型，计算了全球网格上97至500公里高度之间的风、温度、地球位势和离子及中性成分场。通过与地面和空间实验观测进行比较，它可用于详细的案例研究。计划中的模式开发包括对全球电动力学的自洽处理、与磁层的耦合以及向下延伸以纳入中间层。

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.
