CEDAR Science Steering Committee 2007-2009

该项目将支持大气区域耦合、能量学和动力学科学指导委员会(CSSC)的活动。CSSC由来自美国和国际大气科学界的代表组成，由美国国家科学基金会(NSF)任命，并为社区和NSF的空气学和高层大气设施计划之间的沟通提供了一个正式机制。CSSC帮助确定雪松计划的方向和议程，并协调该计划与其他国家和国际计划的活动。CSSC名义上的活动是：(1)每年6月召开年度雪松研讨会；(2)每年秋天在国家科学基金会开会进行规划；(3)出版社区通讯《雪松邮报》，每年两次。今后两年的具体任务包括：(1)编写一份文件，强调地球空间研究的系统科学方法。本文件还将概述DASI倡议的方法，其补充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，特别是在与低海拔耦合、日地相互作用、极地空气动力学和长期变化四个主要科学领域。为了实现这些举措的目标，必须继续重视雪松与新的卫星飞行任务的协作，例如THEMIS、AIM、C/NOFS、阿米西里研究中心等高层大气设施、新的模拟和数据同化计划，以及发展“链和星系团”的概念，重点是实时观测，以便与国家环境保护计划产生协同作用；(3)为新的阿米西里研究中心雷达开展社区协调。虽然阿米西里仪器利用了无线电波的非相干散射，但它的能力超过了今天的高层大气设施ISR的能力。这些能力是基于波束指向的电子方法，而不是机械的，基于阿米西里可以同时指向不同方向的事实，以及它的频率敏捷性。CSSC将与空气动力学社区互动，开发利用阿米西里能力的新的ISR模式。Cedar运动和观测的核心是Cedar数据库档案，该档案被视为新的虚拟日地观测站的重点，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.
