CEDAR Science Steering Committee 2007-2009

本项目将支持大气区域耦合、能量学与动力学科学指导委员会（CEDAR）的活动。CSSC由美国国家科学基金会（NSF）任命的来自美国和国际大气科学界的代表组成，为科学界与NSF的航空和高层大气设施项目之间的沟通提供了正式的机制。CSSC帮助制定雪松项目的方向和议程，并协调该项目与其他国家和国际项目的活动。CSSC的名义活动是：(1)每年6月召开一年一度的雪松研讨会(2)每年秋天在国家科学基金会召开会议以进行规划；(3)每年出版两次社区通讯《雪松邮报》。未来两年的具体任务包括：(1)制定一份强调地球空间研究系统科学方法的文件。该文件还将概述DASI计划的一种方法，其互补的系统工程方法将在未来几十年使CEDAR计划受益；(2)继续实施CEDAR第三阶段计划，特别是在低海拔耦合、日地相互作用、极地航空学和长期变化这四个主要科学领域。为了实现这些倡议的目标，必须继续强调雪松与新卫星任务的合作，如THEMIS、AIM、C/NOFS、高层大气设施，如AMISR、新的建模和数据同化方案，以及“链和集群”概念的发展，重点是与NSWP提供协同作用的实时观测；(3)发展新型高层大气设施AMISR雷达的社区协调。虽然AMISR仪器利用无线电波的非相干散射，但它的能力超过了目前的高层大气设施ISRs。这些能力是基于电子束指向的电子方法而不是机械方法，基于AMISR可以同时指向不同方向的事实，以及它的频率敏捷性。CSSC将与航空界进行互动，开发利用AMISR能力的新型ISR模式。雪松运动和观测的核心是雪松数据库档案，它被认为是新的虚拟太阳地球天文台（VSTO）的重点，因此CSSC将被要求代表社区监督这些发展。

This project will support the activities of the Coupling, Energetics and Dynamics of Atmospheric Regions (CEDAR) Science Steering Committee (CSSC). The CSSC is composed of representatives from the USA and International atmospheric sciences communities, appointed by the National Science Foundation (NSF), and provides a formal mechanism for communication between the community and the NSF's Aeronomy and Upper Atmospheric Facilities Programs. The CSSC helps set the direction and agenda for the CEDAR program and coordinates the program's activities with other national and international programs. The nominal activities of the CSSC are: (1) to convene the annual CEDAR Workshop each June (2) to meet at NSF each fall for planning purposes; and (3) to publish the CEDAR Post, the community's newsletter, twice each year. Specific tasks over the next two years include: (1) developing a document that emphasizes the system science approach to geospace research. This document will also outline an approach for the DASI initiative whose complementary systems engineering approach will benefit the CEDAR program in the coming decades; (2) continuing implementation of the CEDAR Phase III program, particularly in regard to the four main science areas of Coupling to Lower Altitudes, Solar-Terrestrial Interactions, Polar Aeronomy, and Long-Term Variations. To accomplish the goals of these initiatives, continued emphasis must be placed on CEDAR collaborations with new satellite missions, such as THEMIS, AIM, C/NOFS, the Upper Atmospheric Facilities, such as AMISR, new modeling and data assimilation schemes, and the development of chains and clusters" concept with a strong emphasis on real-time observations that provide synergism with the NSWP; (3) developing community coordination for the new Upper Atmospheric Facilities AMISR radars. Although the AMISR instrumentation utilizes the incoherent scatter of radio waves, it has capabilities beyond those of the present-day Upper Atmospheric Facilities ISRs. These capabilities are based upon electronic methods of beam pointing rather than mechanical, upon the fact that the AMISR can point in different directions simultaneously, and its frequency agility. The CSSC will interact with the Aeronomy community to develop new ISR modes that take advantage of the AMISR capability. Central to the CEDAR campaigns and observations is the CEDAR database archive which is being considered as a focus for the new virtual solar terrestrial observatory (VSTO), hence the CSSC will be required to oversee these developments on behalf of the community.
