Magnetometers along the Eastern Atlantic Seaboard for Undergraduate Research and Education (MEASURE-II): A Ground-Based Plasmasphere Monitor Array

本项目将研究超低频波在磁层和电离层中的传播，并将研究磁层内部和等离子体顶的行为。它将扩大并继续在东大西洋沿岸为本科生研究和教育（MEASURE）而设的地面磁力计阵列。MEASURE阵列旨在利用几种技术来确定在内磁层传播的超高频波的固有频率。该阵列将扩展到更高的纬度，即使在相对安静的磁场条件下，也可以常规地确定等离子体顶的位置。磁力计的数据将与电离层和内磁层的总电子含量（TEC）的测量相结合，利用低地球轨道（LEO）卫星和GPS信号。耦合测量将使利用层析成像技术反演数据成为可能，从而产生等离子层粒子密度作为磁场条件函数的新模型。除了基础科学研究外，该项目还包含强大的教育组成部分，涵盖从K-12到本科和研究生水平的教育活动。该项目的研究还涉及与其他磁力计链的国际合作，包括加拿大、南美洲和南极洲的磁力计。

This project will study to propagation of Ultra-Low Frequency (ULF) waves in the magnetosphere and ionosphere and will study the behavior of the inner magnetosphere and the plasmapause. It will expand and continue the operations of the ground-based magnetometer array known as the Magnetometers along the Eastern Atlantic Seaboard for Undergraduate Research and Education (MEASURE). The MEASURE array is designed to exploit several techniques to determine the natural frequencies of ULF waves propagating in the inner magnetosphere. The array will be expanded to include higher latitudes, allowing the measurements to routinely determine the location of the plasmapause, even under relatively quiet magnetic conditions. The magnetometer data will be coupled with measurements of the total electron content (TEC) in the ionosphere and inner magnetosphere by utilizing low earth orbit (LEO) satellites and GPS signals. The coupled measurements will make it possible to invert the data using tomographic techniques to produce a new model of the particle density of the plasmasphere as a function of magnetic conditions. In addition to the fundamental scientific research, the project also contains a strong educational component, covering educational activities from K-12 to undergraduate and graduate levels. The research undertaken by this project also involves international collaborations with other magnetometer chains including magnetometers in Canada and in South America and Antarctica.
