Topside Ionosphere Parameters Observed by POLAR and DMSP at high latitudesSeveral near-simultaneous Southern polar passes for both POLAR (at perigee) and DMSP spacecraft are examined. The core ion measurements from the Thermal Ion Dynamics Experiment (TIDE) on POLAR spacecraft near 5000 km altitude and the ionospheric ion and electron parameters measured by both DMSP 12 and DMSP 13 at 840 kin altitude during these near-simultaneous passes provide unique quasi-global snapshots of the ionospheric flows. We consider such parameters as the O (+) and H (+) densities, temperatures and parallel flows from POLAR/TIDE and the O (+) ion parameters and electron temperature from the DMSP observations. For some passes, auroral images from the POLAR Ultraviolet Imager (UVI) are used to complement the ion/electron parameter observations. We will also examine the interplanetary magnetic field context of these quasi-global topside ionospheric measurements.
