Abstract:
The Canadian face of the Resolute Bay Incoherent Scatter Radar (RISR-C), the newest Advanced Modular Incoherent Scatter Radar (AMISR), recently began routine operations and has been taking detailed measurements of the polar cap ionosphere. Like other AMISR radars, RISR-C has the ability to use electronic beam steering to simultaneously sample ionospheric plasma parameters in several different line-of-sight directions (over 4000 possible beam directions, of which, typically 10-50 are used in a given experiment). Electron density, electron and ion temperatures, and line-of-sight (LOS) plasma velocities are measured along these beam directions at several ranges in (typically) 1-minute intervals. Combining LOS velocity measurements from several different beam directions allows full 3-d ionospheric plasma velocities to be resolved within the field-of-view of the radar. Ionospheric measurements from the southward facing RISR-C are complemented by measurements by the co-located northward facing RISR-N radar operated by SRI International and the REGO redline optical camera operated by the University of Calgary. Initial comparisons between these instruments demonstrate that RISR-C is operating well and will provide vital new measurements of the polar cap ionosphere.
