CEDAR-TIMED: Joint Observations and Studies of the Effects of Geomagnetic Storms

ATM0000958Abb研究人员将在100至150公里高度区域内，利用一组协调一致的地面和定时卫星观测，研究地磁风暴对低热层的影响。计划在关键的高层大气设施进行中性风和温度的地面观测。这项研究将基于一种特殊的警报系统，该系统将使所有非相干散射雷达和相关仪器能够在地磁风暴期间运行。在磁暴期间从定时卫星中选择数据集将提供调查风暴影响所需的数据库。包括大气环流和电动力学模拟工作将加强对全球范围内低热层的结构和动力学的全面了解。

ATM0000958absThe investigators will study geomagnetic storm influences on the lower thermosphere using a coordinated set of ground-based and TIMED satellite observations in the 100 to 150 km altitude region. The ground-based observations of neutral winds and temperatures are planned at key upper atmosphere facilities. The study will be based on a special alert system that will enable all the incoherent scatter radars and associated instrumentation to operate during geomagnetic storm intervals. Selection of data sets from the TIMED satellite during magnetic storms will provide the required data base to investigate storm effects. Inclusion of general circulation and electrodynamic modeling efforts will enhance the overall understanding of the structure and dynamics of the lower thermosphere on a global scale.
