abstract. More than a decade of Cross Polar Cap Potential (CPP) obtained from the SuperDARN radar network is compared to the same parameter derived from the Assimilative Mapping of Ionospheric Electrodynamics technique and calculated from measurements by the Defense Meteorological Satellite Program's Special Sensor-Ions, Electrons, and Scintillation instrument. CPP is a shorthand index used as a measure of the energy flux of the solar wind/magnetospheric energy flux into the ionosphere. We examine the correlations between the different measurements as a function of UT, season, and solar cycle.
