Collaborative Research: Verification and Validation of the NCAR Theromosphere/Ionosphere Electrodynamics General Circulation Model (TIEGCM)

该提案将通过将模型预测与所有现有观测和经验模型预测进行广泛比较，验证NCAR热层/电离层/电动环流模型在各种地球物理条件下的有效性，包括冬季太阳活动极小期、夏季太阳活动极大期以及太阳活动极小期和极大期的春分点。 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）定量地证明模型相对于以前的模型版本，特别是TIGCM的改进;（2）确定TIGCM提供热层/电离层系统良好表示的地球物理条件;（3）确定进一步改进模型的领域，例如赤道电离层的表示。

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.***
