CEDAR: SUNDIAL

这项活动的目的是发展对100-1000公里高度区域电离层热层领域的理论和经验认识。为实现这一目标，建议继续进行日规调查，重点是全球范围的电离层物理、其太阳和行星际控制及其与磁层和热层的耦合，日规调查合并累积的电离层、磁层行星际和太阳输入，并将使用合并的数据来测试第一原理和重要模型，这些模型处理通过地面活动的机会相关卫星方案的测量和“现场”观测。这些数据和模型将在研讨会上进行审查和分析。开发特刊期刊出版物。该数据库将存档，以供后续调查和为发展地球空间预测能力的努力提供基线支持。***

The objective of this activity is the development of a theoretical and empirical understanding of the ionospheric thermospheric domain in the 100-1000 km altitude region. To accomplish this objective it is proposed to continue SUNDIAL investigations focused on global scale ionospheric physics, its solar and interplanetary controls, and its coupling to the magnetosphere and thermosphere, SUNDIAL investigations merge the accumulated ionospheric, magnetospheric interplanetary and solar inputs, and will use the combined data to test first- principle and empherical models dealing with measurements and " in situ" observations from relevant satellite programs of opportunity through ground based activity. The data and models will be reviewed and analyzed in workshops. Special issue journal publications will be developed. The data base will archived for follow-on investigations and baseline support for efforts to develop a geospace prediction capability. ***
