Large-scale traveling ionospheric disturbances observed by GPS total electron content during the magnetic storm of 29-30 October 2003 (2007, background): “Through the observation of the Millstone Hill radar, Foster and Vo [2002] noticed remarkable electronic density trough formed at the geomagnetic latitude of 52 during the storm of 12 April 2001.”
Control of plasmaspheric dynamics by both convection and sub‐auroral polarization stream (2003, methodology): “Although no parametric model of the SAPS E-field is currently available, SAPS statistical properties [Foster and Vo, 2002] can in principle be used to construct a SAPS model that can be iteratively improved through comparison with global EUV observations.”
Multiradar observations of the polar tongue of ionization (2005, methodology): “…are seen in the pre-midnight and afternoon sector at the equatorward edge of the main ionospheric trough and stream sunward carried by the low-latitude edge of the subauroral disturbance electric field (the subauroral polarization stream, SAPS [Foster and Burke, 2002; Foster and Vo, 2002]).”
A decade of the Super Dual Auroral Radar Network (SuperDARN): scientific achievements, new techniques and future directions (2007, background): “These sub-auroral electric fields play critical roles in energising and transporting ring current ions as well as convecting thermal plasma in the inner magnetosphere and in the mid- to low-latitude ionosphere (Foster and Vo 2002).”
The Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) on RBSP (2013, background): “While the general characteristics of SAPS are well-documented and understood from ionospheric and low-altitude observations (e.g., Foster and Vo 2002; Mishin et al. 2003), the magnetospheric signature has not been as extensively investigated.”
Differences between CME‐driven storms and CIR‐driven storms (2006, background): “SAPS and SAID events have been observed and analyzed for several CME-driven storms [e.g., Foster et al., 1994; Garner et al., 2004; Foster and Vo, 2002], but no comparisons have been made for their occurrence probabilities and properties for CIR versus CME-driven storms.”
GPS observations of the ionospheric F2-layer behavior during the 20th November 2003 geomagnetic storm over South Korea (2008, background): “…thermospheric meridian winds, a “composition bulk” and high latitude particle precipitation have been suggested as probable physical mechanisms to explain the ionospheric response to the storm induced disturbances (Fuller-Rowell et al. 1994; Foster 1993; Foster and Vo 2002; Tsurutani et al. 2004).”
GPS and ionospheric scintillations (2007, background): “scintillations in Figure 14 were at least partially associated with the fast ionospheric drifts in subauroral polarization streams (SAPS) [Foster and Vo, 2002].”
Space Weather Effects in the Earth’s Radiation Belts (2018, background): “The study concluded that SED plasma was transported sunward (westward) in the sub-auroral polarization stream (SAPS, Foster and Vo 2002) at speeds of ∼1 km/s. SED flows at ionospheric altitudes provide significant heavy ion fluxes into the high latitude F-region cusp ionosphere with magnitude ≥1.0…”
Global dayside ionospheric uplift and enhancement associated with interplanetary electric fields (2004, neutral): “At this time we do not know how this GPS signature is related to Subauroral Polarization Streams (SAPS) [Foster and Vo, 2002; Foster et al., 2002].”
