Dayside Cavity Mode Oscillations in the Inner Magnetosphere

这个项目将确定是否超低频（ULF）腔模波存在于地球的内磁层，如果他们这样做，等离子体如何控制他们的属性。 该项目将利用麦克马克磁力计阵列的地面磁脉动测量。 地面脉动数据将由ACE卫星的太阳风测量值以及Geotail和GOES卫星的磁脉动测量值加以补充。 数据分析将包括三维磁流体动力学（MHD）模拟使用一个现实的等离子体密度结构。 腔模波在辐射带中粒子的输运和散射中可能起着重要作用。

This project will determine whether or not Ultra Low Frequency (ULF) cavity mode waves exist in Earth's inner magnetosphere and if they do, how the plasmasphere controls their properties. The project will make use of ground-based magnetic pulsation measurements from the McMAC magnetometer array. The ground-based pulsation data will be supplemented with solar wind measurements from the ACE satellite and magnetic pulsation measurements from the Geotail and GOES satellites. The data analysis will include 3-dimensional magnetohydrodynamic (MHD) simulations using a realistic plasmasphere density structure. Cavity mode waves may play an important role in the transport and energization of particles in the radiation belts.
