Research Projects

• Sub-auroral convection electric fields

  Sub-auroral convection electric fields

  Sub-auroral convection electric fields focuses on the study of ionospheric plasma convection in the plasmasphere boundary layer region where complex coupling between the ionosphere and magnetotail occur during geomagnetically disturbed periods. Measurements from the mid-latitude SuperDARN radars are used in conjunction with other ground and space-based observations of sub-auroral phenomena.

• Convection electric field climatology and variability

  Convection electric field climatology and variability

  Convection electric field climatology and variability focuses on the large-scale convection of plasma in the Earth's polar ionospheres. Measurements from the SuperDARN network of HF radars are used to look at statistical properties of convection associated with various drivers as well as the observed small-scale variability.

• Mid-latitude HF radar development

  Mid-latitude HF radar development

  A network of HF radars are being built at several mid-latitude locations to measure ionospheric electric fields. This project involves the construction, maintenance and operation of several HF SuperDARN radars that have recently been built or are in the planning stages.
