Statistics of total electron content depletions observed over the South American continent for the year 2008 (2011, background): “[38] Figure 11 indicates that there are almost no depletions in the June solstice (except for a few events during June 2008). This is the period when the ITCZ moves farther away from the magnetic equator and no convective systems can trigger gravity waves (GWs) [Tsunoda, 2010a]. The June solstice is”
Prompt penetration electric fields (PPEFs) and their ionospheric effects during the great magnetic storm of 30-31 October 2003 (2008, methodology): “However, for the interested reader, we refer them to Mannucci et al. [2005a], Foster et al. [2005] , and Foster and Coster [2007].”
Assimilation of GIRO data into a real‐time IRI (2012, background): “…can be devised to identify and preserve large-scale features of storm-enhanced ionospheric plasma, such as the plumes and tongues of ionization [Foster et al., 2005], that can be inferred from GIRO fragmentary data or imported from alternative data resources describing, for example, the…”
Canadian High Arctic Ionospheric Network (CHAIN) (2009, methodology): “…spatial dimensions plus time) tomographic inversions of the ionosphere using the MultiInstrument Data Analysis System (MIDAS) [Mitchell and Spencer, 2003; Bust et al., 2007] or the Global Assimilative Ionospheric Model (GAIM) [Hajj et al., 2004] for addressing some of the scientific objectives.”
Review of the accomplishments of mid-latitude Super Dual Auroral Radar Network (SuperDARN) HF radars (2019, background): “Previous efforts to determine the connection between mid-latitude SED and polar TOI were hampered by the inability of the high-latitude SuperDARN radars to observe the lower latitude sunward convecting regions believed to be crucial in this global plasma circulation (Foster et al. 2005).”
Sharpening our thinking about polar cap ionospheric patch morphology, research, and mitigation techniques (2012, background): “Moen et al. [2000] pointed out that Superdarn echoes have a faster onset than expected from GD.”
Space Weather Effects in the Earth’s Radiation Belts (2018, background): “33B) creating a tongue of ionization (TOI, Foster et al. 2005) stretching across the polar cap to the midnight sector.”
Space weather challenges of the polar cap ionosphere (2017, background): “The solar-EUV ionized plasma enters the polar cap through the cusp inflow region and forms the tongue of ionization (TOI) (Knudsen 1974; Foster et al. 2005; Moen et al. 2008a).”
