• Connections between deep tropical clouds and the Earth's ionosphere (2007, background): “[3] Recent analyses of IMAGE FUV observations reveal four longitudinal EIA enhancements in the early evening, which can be attributed to comparatively stronger equatorial plasma fountain effects at each of these locations [ Sagawa et al., 2005; Immel et al., 2006; England et al., 2006a, 2006b].”
• Electrodynamics of the formation of ionospheric wave number 4 longitudinal structure (2008, background): “[2] A wave number 4 longitudinal structure has recently been found in the low-latitude ionospheric density distribution by a number of satellite observations, both for the nighttime [ Sagawa et al., 2005; Immel et al., 2006; England et al., 2006a, 2006b; Lin et al., 2007a] and daytime [Lin et al., ”
• Variability and predictability of the space environment as related to lower atmosphere forcing (2016, methodology): “This is consistent with the observational finding by Phillips and Briggs [1991], that there is a lack of correlation between the variability of the ionospheric currents and the variability of tidal winds measured at Buckland Park, 35∘S, 138∘E. Yamazaki et al. [2014] demonstrated that the observed da”

• Plausible effect of atmospheric tides on the equatorial ionosphere observed by the FORMOSAT‐3/COSMIC: Three‐dimensional electron density structures (2007, methodology): “[7] The most likely wave mode responsible for the fourpeaked longitudinal structure is the eastward wavenumber three (E3) diurnal nonmigrating tide [Sagawa et al., 2005; Immel et al., 2006; England et al., 2006a, 2006b].”
• Wavenumber‐4 patterns of the total electron content over the low latitude ionosphere (2008, result): “[12] As suggested by previous works [Sagawa et al., 2005; England et al., 2006a; Immel et al., 2006; Hagan et al., 2007], the longitudinal wavenumber-4 structure in the EIA region may be caused by the longitudinal modulation of the F-region ion drifts which is created in turn by the longitudinal…”
