AGS-PRF: Development of a Data Assimilation Model for the Plasmasphere

这是一个跨学科项目，旨在扩展现有的电离层数据同化技术，以开发一种新的最先进的等离子层成像和数据同化技术。它将利用对等离子层密度的各种观测来生成等离子层中电子密度随时间变化的图。然后，这些地图将被输入等离子体圈的第一性原理模型，以产生更正和改进的等离子体圈动力学特征和预测。该方法将通过仿真进行测试和验证。最后，该技术将用于实际的GPS和原位测量，以解决电离层-等离子层耦合的问题，通过重新填充和侵蚀，以及等离子层羽流的特征。这项工作将在奥格斯堡学院进行，由Murr博士指导，并与大气与空间技术研究协会的Bust博士和海军研究实验室空间物理部门的Huba博士合作。该项目将涉及奥格斯堡学院的本科生。该项目将产生一种更准确、更有效地预测等离子层状态的实用方法。等离子层动力学是理解空间天气对电离层影响的重要组成部分。因此，新模型将有助于提高我们的空间天气预报能力。

This is an inter-disciplinary project to expand existing ionospheric data assimilation techniques to develop a new state-of-the-art imaging and data assimilation technique for the plasmasphere. It will use a variety of observations of plasmaspheric densitites to produce time-evolving maps of the electron density i nthe plasmasphere. These maps will then be fed into first-principles models of the plasmaspehre to produce corrected and improved characterisations and predictions of plasmasphere dynamics. The method will be tested and validated via simulations. Finally, the technique will be used on real GPS and in-situ measurements to address questions of ionosphere-plasmasphere coupling through refilling and erosion, and for characterizations of plasmasphere plumes. The work will be carried out at Augsburg College under the mentorship of Dr. Murr and in collaboration with Dr. Bust of Atmospheric & Space Technology Research Associates and Dr. Huba of the Space Physics Section at the Naval Research laboratory. The project will involve undergraduate students at Augsburg College. The project will produce a practical methodology to predict the state of the plasmasphere more accurately and more efficiently. Plasmasphere dynamics is an important ingredient in understanding space weather effects in the ionosphere. Therefore, the new model will help improve our space weather forecasting capabilities.
