CEDAR: Whole Atmosphere Modeling of the Thermosphere/Ionosphere Responses to Lower-Atmosphere Dynamics and Variability

全大气群落气候模式（WACCM）通过将上界扩展到550 km，并通过（从其他模式）适应热层-电离层能量、动力和成分相互作用的物理算法而得到改进。新模式还建立了表征重力波强迫和潮汐耦合的新参数化，完成了全面的全大气模拟方法。最终的模型，包括源代码，在国家大气研究中心的应用支持下，向整个社区开放。模型验证是由研究团队进行模型和数据比较，并与独立的外部调查人员合作完成的。特别强调的是在全球气候变化的背景下评估高层大气对微量物质、温度和低层大气动力学的长期变化的响应。

The Whole Atmosphere Community Climate Model (WACCM) is improved by extension of the upper boundary to 550 km, and by adaptation (from other models) of physical algorithms for thermosphere-ionosphere energetic, dynamic, and composition interactions. New parameterizations characterizing gravity-wave forcing and tidal coupling are also established in the new model, completing a comprehensive whole-atmosphere modeling approach. The resultant model, including source code, is made available to the entire community with application support from the National Center for Atmospheric Research. Model validation is accomplished by model and data comparisons performed by the research team, and by collaboration with independent outside investigators. Particular emphasis is placed on evaluating upper atmospheric response to secular changes in trace species, temperature, and dynamics in the lower atmosphere in the context of global climate change.
