Collaborative Research: A Comprehensive Data Base of Global Reconnection Measurement

该项目将量化大范围太阳风条件下全球重联率的时空变化。重联率将通过使用穿过开合磁场线边界的磁通量的变化来计算。计算将利用卫星图像确定极帽边界及其变化，而SuperDARN观测和AMIE技术将用于计算极帽对流。AMIE技术使用地磁观测。计算将给出磁层顶和磁尾重联的重联率。它们将用于广泛的磁层活动，包括稳定的磁层对流事件、亚暴、CME和CIR风暴。他们将在SuperMAG中创建一个观测和代码库，用于计算任何太阳风和磁层条件下的重联势。这项工作将支持一名研究生，APL的团队将继续积极参与各级STEM教育。

This project will quantify the temporal and spatial variation of the global reconnection rates for a large range of solar wind conditions. The reconnection rate will be calculated by using the change in the magnetic flux that crosses the open-to-closed field line boundary. The calculation will make use of satellite images to determine the polar cap boundary and its changes while SuperDARN observations and the AMIE technique will be used to calculate polar cap convection. The AMIE technique uses ground magnetic observations. The calculations will give the reconnection rates for both magnetopause and magnetotail reconnection. They will be carried out for a wide range of magnetospheric activity including steady magnetospheric convection events, substorms and CME and CIR storms. They will create in SuperMAG a repository of the observations and code that will allow calculations of reconnection potentials for any solar wind and magnetospheric conditions. The work will support a graduate student and the team at APL will continue to be active in STEM education at all levels.
