“…The observed strong day-night asymmetry and the lack of significant partial ring current in the dayside afternoon sector argues against the details in most drift trajectory models that predict a morning-afternoon asymmetry due to a partial ring current in the afternoon sectors (Ejiri, 1978;Chen et al, 1993;Liemohn et al, 2001). Our results indicate that the partial ring current closes via meridional currents near dawn and dusk and not near noon and midnight.…”

“…The intensity of the ring current during storm evolution has also been studied using a complementary approach of computing energetic particle transport in different field geometries, and the ground magnetic disturbance (D st ) using the Dessler-Parker-Sckopke (Dessler and Parker, 1959;Sckopke, 1966) relationship (see, for example, Chen et al, 1993;Fok and Moore, 1997;Jordanova et al, 1997;Ebihara and Ejiri, 2000;Liemohn et al, 2001;Ganushkina and Pulkkinen, 2002). These models have, in principle, a possibility to separate between open drift paths (asymmetric ring current) and closed drift paths (symmetric ring current).…”

“…They have been used both successfully and unsuccessfully to reproduce the observed features of the stormtime ring current (e.g. Chen et al, 1993Chen et al, , 1999Kozyra et al, 1998Kozyra et al, , 2002andLiemohn et al, 2001, 2002). Only recently (from the IMAGE satellite) have global snapshots of the plasma morphology in the inner magnetosphere been obtained with a quality suitable for detailed, quantitative analysis (Burch et al, 2001), and progress in extracting the electric field from these images is slow.…”
