• Variability and predictability of the space environment as related to lower atmosphere forcing (2016, background): “…of the four wave structures in the equatorial ionosphere anomaly (EIA) and equatorial electrojet (EEJ) [Sagawa et al., 2005; Immel et al., 2006; Hagan et al., 2007; Lühr et al., 2008], LIU SPACE WEATHER AND TERRESTRIAL WEATHER 635 and ionospheric responses during stratospheric sudden warming…”
• Development and Validation of the Whole Atmosphere Community Climate Model With Thermosphere and Ionosphere Extension (WACCM‐X 2.0) (2018, background): “…General Circulation Model (TIME-GCM; Roble & Ridley, 1994) have lower boundaries at 97 and 30 km, respectively; these lower boundary conditions are specified using tidal parameterizations or observed meteorological fields (e.g., Hagan et al., 2007).”
• Wave-driven variability in the ionosphere-thermosphere-mesosphere system from TIMED observations: What contributes to the wave 4 ? (2011, methodology): “[4] First principles modeling by Hagan et al. [2007] supports the E‐region electric field modulation process.”
• Electrodynamics of the formation of ionospheric wave number 4 longitudinal structure (2008, methodology): “On the other hand, wave number 4 structure has been found in the F-region zonal wind during the evening hours, observed in phase with the strength of equatorial ionization anomaly [Lu¨hr et al., 2007], and the propagation of DE3 up to the F-region has also been predicted by other models [e.g., Haga”
• Internal wave coupling processes in Earth's atmosphere (2014, unknown): “GCM simulations (Hagan et al., 2007) have confirmed this mechanism, while the subsequent studies investigated its various aspects (Ren et al., 2010).”
• A theory of ionospheric response to upward‐propagating tides: Electrodynamic effects and tidal mixing effects (2013, background): “In fact, observational and numerical studies have shown that upward-propagating nonmigrating tides play an essential role in producing a longitudinal structure in F region plasma density [e.g., Immel et al., 2006; Hagan et al., 2007] and thermospheric neutral density [e.”
• Tidal propagation of deep tropical cloud signatures into the thermosphere from TIMED observations (2008, methodology): “Recent model simulations [Hagan et al., 2007] support the idea that DE3 propagates upward into the thermosphere where the induced neutral wind modulation around 110–150 km interacts with the Eregion plasma, thus affecting the equatorial fountain and finally the EIA around 400 km altitude.”
• Tropospheric tidal effects on the middle and upper atmosphere (2009, methodology): “[18] Our investigation demonstrates that the DE3 can penetrate into the upper thermosphere and directly modulate the thermosphere-ionosphere coupling processes at F region altitudes.Thus,thewave4signaturesobservedintheFregion may result from a combination of these direct effects and the indirect eff”
• 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…”
• Nonmigrating tidal signals in the upper thermospheric zonal wind at equatorial latitudes as observed by CHAMP (2009, methodology): “Comparing the annual variation of DE2 and DE3 at 400 km altitude with those for the zonal wind at 100 km altitude derived from SABER and TIDI measurements onboard the TIMED satellite (Pedatella et al., 2008), we find a big resemblance of the annual variation between the two altitude levels.
