This proposal will validate the NCAR thermosphere/ionosphere/electrodynamic general circulation model (TIEGCM) for a variety of geophysical conditions, including winter solar minimum, summer solar maximum, and equinox for both solar minimum and maximum, by extensive comparison of the model predictions with all available observations and with predictions from empirical models. The PIs will emphasize the predicted thermosphere/ionosphere coupling, particularly the representation of the atmospheric dynamo. Results of this study will (1) demonstrate quantitatively the model improvement over previous model versions, especially the TIGCM; (2) establish the geophysical conditions for which the TIEGCM provides a good representation of the thermosphere/ionosphere system; and (3) identify areas for further model improvements, such as the representation of the equatorial ionosphere.***

这一提议将通过将模型预测与所有现有观测以及经验模型的预测进行广泛比较，验证NCAR热层/电离层/电动大气环流模型(TIEGCM)在各种地球物理条件下的有效性，包括冬季太阳最小值、夏季太阳最大值以及太阳最小值和最大值的春分。PI将强调预测的热层/电离层耦合，特别是大气发电机的表示。这项研究的结果将：(1)从数量上证明模式比以前的模式版本有所改进，特别是TIGCM；(2)确定TIEGCM能够很好地代表热层/电离层系统的地球物理条件；(3)确定模式需要进一步改进的领域，如赤道电离层的代表。
