This project will produce results on a number of topics in the field of solar terrestrial physics. At the core of this activity will be the study of energy transfer through the solar wind-magnetosphere-ionosphere system. Specifically, investigation of the variability of the electron density structure in the East Asian sector will be undertaken as well as their effects on HF radio propagation.
An understanding of the latter will enable the study of atmospheric gravity waves to quantify how they distribute the energy deposited into the auroral zone to lower latitudes. The penetration of the electric field to lower latitudes will also be determined, and a new numerical model of the electric field based on spacecraft observations will be produced. This work will also prepare the way for the construction and deployment of new radars which will contribute to the Super Dual Auroral Radar Network (SuperDARN).
