Long-term Observations of the Arctic Upper Atmosphere Using the Kodiak, Alaska SuperDARN Radar: Environmental

主要研究人员正在寻求资金，以支持称为超级双极光雷达网络（SuperDARN）的新雷达的长期运行。 SuperDARN是位于北方和南方半球高纬度地区的高频多普勒雷达网络。 雷达对产生这种漂移的电离层电场的反向散射很敏感。 SuperDARN是目前唯一能够对高纬度电场进行连续、大规模、直接观测的实验技术。 这个磁场之所以令人感兴趣，是因为它在能量和动量从地球磁层向高层大气转移方面发挥着作用。 电场是太阳风和磁层之间相互作用的结果，以及磁层内发生的许多等离子体过程。 它的全球结构和动力学的知识是基本的了解大规模的等离子体过程在近地空间环境中，并在确定的重要性，电动力学能量输入到高纬度地区的地球的高层大气中。科迪亚克SuperDARN雷达是一个新的设施，是由美国国家科学基金会的极地计划办公室的资助下建造的。 它将成为SuperDARN雷达网络的一个组成部分，并将实现美国北极研究在高纬度高层大气和近地空间的目标。科迪亚克SuperDARN雷达的建设即将完成，重要的是要建立一个支持基地为其运行提供支持。 该项目展示了这个新设施将提供的测量的重要性以及围绕SuperDARN网络建立的研究社区的活力。 科迪亚克雷达的运行将加强超级DARN对北极研究的重大贡献。

Abstract OPP-9981866The principal investigator is seeking funds to support the long-term operation of new radar called the Super Dual Auroral Radar Network (SuperDARN). SuperDARN is a network of (high frequency) HF Doppler radar located in the high latitude regions of the Northern and Southern hemispheres. The radar is sensitive to backscatter from ionspheric electric fields that produce this drift. SuperDARN is the only currently available experimental technique capable of providing continuous, large scale, direct observations of the high-latitude electric field. This field is of interest because of its role in the transfer of energy and momentum from the Earth's magnetosphere to the upper atmosphere. The electric field is a consequence of the interaction between the solar wind and the magnetosphere and many plasma processes occurring within the magnetosphere. Knowledge of its global structure and dynamics are fundamental to understanding large-scale plasma processes in the near Earth space environment, and in deter mining the importance of electrodynamics energy input to the high-latitude regions of the Earth's upper atmosphere.The Kodiak SuperDARN radar is a new facility that was constructed under a grant from the National Science Foundation's Office of Polar Programs. It will act as an integral part of the SuperDARN radar network and will address the goals of U.S. Arctic research in the high-latitude upper atmosphere and near-Earth space.A construction of the Kodiak SuperDARN radar nears completion, it is important that a base of support be established for its operation. This project demonstrates the importance of the measurements that this new facility will provide and the vitality of the research community that has been built up around the SuperDARN network. Operations of the Kodiak radar will enhance the already significant contributions of SuperDARN to arctic research.
