Collaborative Research: Auroral Radio Emissions Related to Substorms and Energetic Precipitation

该项目是达特茅斯学院、安柏瑞德学院和锡耶纳学院的三方合作项目。在之前的一项拨款中，该小组在几个高纬度天文台检查了低频、中频和高频无线电发射。该仪器利用干涉测量法提供测向信息，以便定位观测到的发射源区域。该提案将使用现有的无线电干涉仪和频谱分析仪，与英里计、磁力计、全天候照相机、光度计、ISR和超级雷达一起研究无线电发射与亚暴和高能粒子降水的关系。该项目将集中研究最不为人所知的极光发射形式，即所谓的中频爆发。有两个主要目标：(1)确定高频暴的产生机制；(2)确定高频暴与极光加速过程和亚暴现象的关系。该项目包括研究生和本科生的研究机会。这些数据将公开提供，可能对参与加拿大e-Pop卫星任务和美国宇航局THEMIS任务的研究人员有用。

This project is a three-way collaboration between PIs at Dartmouth, Embry-Riddle and Siena College. In a previous grant the team examined LF, MF, and HF radio emissions at several high latitude observatories. The instrumentation utilized interferometry to provide direction finding information in order to locate the source region of the observed emissions. This proposal will use the existing radio interferometers and spectrum analyzers in conjunction with riometers, magnetometers, all-sky cameras, photometers, ISR and SuperDARN radars to investigate the relationship of the radio emissions to substorms and to energetic particle precipitation. The project will concentrate on the least well understood form of auroral emission, what is known as an MF-burst. There are two primary goals: (1) to determine the generation mechanism of MF-bursts and (2) to determine the relationship of the MF-bursts to auroral acceleration processes and substorm phenomena. The project includes research opportunities for both graduate and undergraduate students. The data will be made publicly available and is likely to be useful to researchers involved with the Canadian e-Pop satellite mission and the NASA THEMIS mission.
