Scientific paper

The newly enhanced SuperDARN HF radar network, together with All-Sky and Narrow Field of View Imagers operated as part of the Canadian GeoSpace Monitoring and THEMIS Ground-Based Observatory programs, and the new Resolute Bay AMISR Incoherent Scatter Radar are now capable of observing convection and the aurora with an unprecedented combination of spatio-temporal resolution and geographic extent. These observations extend across orders of magnitude of spatial and temporal scales, and provide contiguous coverage extending from the polar cap to sub-auroral latitudes and across many hours of MLT. We are now in a position to carry out innovative new studies of the convection cycle, how it is related to magnetospheric instabilities, and how it leads to the formation of the aurora. In this talk I will provide an overview of these exciting new observational capabilities, focusing particularly on studies that will be enabled by combining optical and convection measurements in the polar cap and the high-latitude auroral zone.
