Ionospheric dynamics in the polar cap
Entry ID: ASAC_949

Abstract: The aim is to measure structure and drift in polar-cap ionospheric layers in order to test current theories and models, identify unexplained behaviour and develop theoretical explanations. The polar cap ionosphere is affected significantly by conditions in the solar wind, so it is important to understand this outer region of our environment, not just to extend our knowledge, but to improve space weather predictions. Specific outcomes will include advances in understanding and predicting the behaviour of the polar cap ionosphere, development of new ionospheric radar techniques, improved models of the polar cap electric field and training of postgraduate students.
