PolarDARN (The northern hemisphere polar portion of the international SuperDARN (Super Dual Auroral Radar Network) program).
Principal Investigator: Sofko, George J
Licenced Year(s): 2013 2012 2011 2010 2009 2008 2007 2004
Summary: Just as high and low pressure systems drive normal weather, high and low voltages drive space weather. The radar network is designed to measure these voltage patterns several hundred kilometers above the ground, as these patterns project out into space along the Earth's magnetic field lines. This information is critical to personnel in space and to maintenance of the satellite telecommunications. ...


High latitude studies of the ionosphere E-region using the Sapphire North Radar System
Principal Investigator: Sofko, George J
Licenced Year(s): 1994
Summary: The Sapphire North Radar System uses 2 transmitters, at Sachs Harbour and Rankin Inlet, and a common receiver at Yellowknife. This system measures speeds of structures in the ionosphere (upper atmosphere) in order to study the transfer of energy from the solar wind to the earth. This energy transfer is most apparent during "magnetic storms" when there are displays of northern lights. The researc...
