Impact of sudden stratospheric warmings on equatorial ionization anomaly (2010, background): “The estimated portion of ionospheric variability not accounted for by these drivers is typically ∼20% of the F‐region maximum electron density at daytime and ∼33% at night [i.e., Forbes et al., 2000; Rishbeth and Mendillo, 2001; Mendillo et al., 2002 ].”
Equatorial and Low Latitude Ionospheric Effects During Sudden Stratospheric Warming Events (2011, background): “Similarly, changes of up to 20% in daytime F-region maximum electron density that cannot be associated with solar or magnetic drivers have been reported by Rishbeth and Mendillo (2001) and Mendillo et al. (2002).”
GPS observations of the ionospheric F2-layer behavior during the 20th November 2003 geomagnetic storm over South Korea (2008, background): “Nonchemical causes include dynamical changes of vertical ion motions induced by winds and E×B drifts; e.g., Mendillo et al. (2002) suggested the wind variability effect on the ionospheric variability.”
An update to the Horizontal Wind Model (HWM): The quiet time thermosphere (2015, methodology): “Meteorological forcing are either specified as time-dependent lower boundary conditions [Mendillo et al., 2002; Siskind et al., 2012] or via nudging techniques [Sassi et al., 2013; Siskind et al., 2014].”
Seasonal variation of thermospheric density and composition (2009, background): “Mendillo et al. [2002] found that composition change is related to the seasonal variation in NmF2 but that temperature variation has a more significant influence on the F2-layer height hmF2, and Mendillo et al. [2005] compared the annual (June/December) asymmetry in total electron content to O/N2 a”
Storms in the ionosphere: Patterns and processes for total electron content (2006, background): “Upward coupling is a highly significant mechanism contributing to the overall day-to-day variability of the ionosphere [Forbes et al., 2000; Rishbeth and Mendillo, 2001; Mendillo et al., 2002]; increased progress in this area is a critical need.”
Why is there more ionosphere in January than in July? The annual asymmetry in the F2-layer (2006, methodology): “Furthermore, Mendillo et al. (2005), using global data from only two days in July 2002 and January 2003, found that the O/N 2 ratio derived from the GUVI experiment on the TIMED satellite (Christensen et al.”
Ionospheric signatures of sudden stratospheric warming: Ion temperature at middle latitude (2008, background): “Portion of ionospheric variability not accounted by these drivers typically amounts to 20% of F-region maximum electron density [i.e., Forbes et al., 2000; Mendillo et al., 2002 ] and is thought to be associated with lower atmospheric processes.”
A statistical analysis of ionospheric anomalies before 736 M6.0+ earthquakes during 2002-2010 (2011, unknown): “[3] There are many reports about the pre‐earthquake ionospheric anomalies (PEIA) for some special earthquake events from the 1970s, while it is not sufficient to draw the conclusion that these anomalies are really related to the incoming earthquake because the ionospheric F2 layer has significant da”
