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.

这个项目是达特茅斯、安柏瑞德和锡耶纳学院的PI之间的三方合作。在之前的一项资助中，该团队检查了几个高纬度天文台的LF，MF和HF无线电发射。该仪器利用干涉测量法提供测向信息，以便确定所观测到的辐射源区域的位置。这项建议将使用现有的无线电干涉仪和频谱分析仪，并结合测高仪、磁强计、全天空照相机、光度计、ISR和SuperDARN雷达，调查无线电发射与亚暴和高能粒子降水的关系。该项目将集中在最不为人所知的极光发射形式，即所谓的MF爆发。有两个主要目标：（1）确定MF爆发的产生机制;（2）确定MF爆发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卫星使命和美国航天局THEMIS使命的研究人员有用。
