3A Comparison of SuperDARN-Derived Plasma Convection and DMSP Ion Drift Measurements显示文摘Recently several studies indicated possible deterioration of accuracy in the SuperDARN convection measurements at large distances (>2 500 km). In this study, the SuperDARN-derived convection was compared with ion drift measurements given by the DMSP satellites, focused on SuperDARN far-range measurements, to investigate the above-mentioned problem. Two different procedures of SuperDARN convection estimation were applied. An overall reasonable agreement between two observation systems were found though individual points in some passes show significant differences. Besides, a tendency is also clear that the SuperDARN-derived velocities were slightly smaller than those of DMSP ion drift measurements. Potential factors contributing to the velocity differences were explained.XU Liang XU Jisheng Koustov Alexandre Papitashvili Vladimir Rich Fedrich 2007Wuhan University Journal of Natural Sciences2007,12,2:1

9Assessing Doppler velocities of Rankin Inlet F-region echoes显示文摘Doppler velocities observed by the Rankin Inlet (RKN) PolarDARN radar are assessed with a focus on data in the beams oriented roughly along the magnetic meridian. Hourly scatter plots for every month are built. They are shown to vary widely, with median values showing very clear magnetic local time variation with maximum magnitude during pre-noon and pre-midnight hours. The histograms contain a significant amount of very small velocity data that dominates at farther ranges and during the daytime. Near noon data show generally antisunward flows but at large ranges/magnetic latitudes and very close to noon, sunward flows occur for periods of positive IMF B z . The reverse flows are stronger during spring equinox. The velocity magnitude was found to depend linearly on the IMF B z and interplanetary electric field. Velocities are often found to be smaller than those expected from the statistical convection model of Ruohoniemi and Greenwald-1996.Alexander V Koustov Kale Colville Robyn A D Fiori Mohsen Ghezelbash 2013Advances in Polar Science2013,24,1:0
