Space Weather: Point-Mosaic Auroral Zone Imaging

该项目的目标是获得连续的、全球的、实时的极光大小、结构和动态监测，用于空间天气规范和预警系统，以及作为全球环流模式输入的近期预报。这种方法是基于这样一种观测，即0.1 - 100赫兹的磁波动似乎是卫星高度极光椭圆的一个很好的标识符。这样就有可能利用商业通信和导航卫星套件上用于确定姿态的非科学级磁力计来提供对极光椭圆的连续监测。该项目将对磁波动进行更彻底的调查，并将检查来自RIDIUM姿态磁强计的测试数据，以测试所提议方法的有效性。

The objective of this project is to obtain continuous, global, real-time monitoring of the auroral size, configuration, and dynamics for use in space weather specification and warning systems and for near-term forecasting as an input to global circulation models. The method is based upon the observation that 0.1 - 100 Hz magnetic fluctuations appear to be a good identifier of the auroral oval at satellite altitudes. It may be possible then to utilize non-science grade magnetometers used for attitude determination on the suites of commerical communication and navigation satellites to provide continuous monitoring of the auroral oval. The project will undertake a more thorough investigation of the magnetic fluctuations and will examine test data from the RIDIUM attitude magnetometer to test the efficacy of the proposed method.
