Brief description Ground based monitoring of plasma dynamics in the magnetosphere. We will use a new technique to study the plasmapause, a fundamental and highly dynamic boundary in geospace. This is usually examined using spacecraft and ground-based VLF measurements, but these suffer several limitations. We have developed the ability to monitor plasma density in geospace, by measuring the resonant frequency of geomagnetic field line oscillations. This project will use data from extensive ground magnetometer arrays to thus study the spatial and temporal variation in particle density near the plasmapause. Comparison with VLF and spacecraft measurements will provide new information on the plasma composition and dynamics in this important region.
