• Multiradar observations of the polar tongue of ionization (2005, background): “…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]).”
• Control of plasmaspheric dynamics by both convection and sub‐auroral polarization stream (2003, background): “[3] Although consistent with zero-order plasmasphere behavior during active times, the simple convective picture ignores some known or suspected complicating effects such as (but not limited to) ionospheric filling, inhomogeneity in ionospheric conductivity, violations of the ‘frozen-in-flux’ condit”
• Simultaneous remote sensing and in situ observations of plasmaspheric drainage plumes (2004, methodology): “…speeds seen inside the narrow duskside plume (L1 from 0200–0400 UT) may be due to the subauroral polarization stream (SAPS) [Goldstein et al., 2003b], an intense narrow flow channel that arises during disturbance times as a consequence of ring-current/ionosphere coupling [Foster and Burke, 2002].”
• A decade of the Super Dual Auroral Radar Network (SuperDARN): scientific achievements, new techniques and future directions (2007, background): “Foster and Burke (2002) introduced the term ‘sub-auroral polarization stream’ (SAPS) to encompass all these phenomena, also including broader (3–58), weaker (100–400 m/s), background flows which persist beyond midnight into the predawn sector.”
• Average characteristics and activity dependence of the subauroral polarization stream (2002, methodology): “This subauroral polarization stream and deep F region ionization trough lies within the region of the region 2 (R2) fieldaligned currents identified with the DMSP magnetometer data (not shown) [Foster and Burke, 2002].”
