• Anomalously low solar extreme‐ultraviolet irradiance and thermospheric density during solar minimum (2010, methodology): “Solar EUV irradiance is the most important parameter affecting thermospheric density, but short‐term perturbations from geomagnetic activity, and periodic seasonal variation due to changes in Sun‐Earth distance and atmospheric circulation, also play a role [cf. Qian et al., 2009].”
• WHOLE ATMOSPHERE MODELING: CONNECTING TERRESTRIAL AND SPACE WEATHER (2011, background): “It has also been suggested that the SAO in thermospheric density and composition [Paetzold and Zschörner, 1961; Cook, 1969] may be driven by seasonally varyingmixing generated in theMLT by gravity waves [Qian et al., 2009].”

• Causes of low thermospheric density during the 2007–2009 solar minimum (2011, methodology): “…of heating rates, chemical terms, heat conduction, and cooling rates, are always a work in progress, although considerable effort has gone into obtaining an accurate relationship betweenmodel simulations and neutral density measurements over solar cycle 23 [e.g., Qian et al., 2009].”
• Thermosphere extension of the Whole Atmosphere Community Climate Model (2010, unknown): “The turbulent mixing from gravity wave breaking in the mesosphere and lower thermosphere (MLT) plays an important role in the exchange of constituents between the mesosphere and thermosphere, which may in turn control the thermospheric density [Qian et al., 2009].”
• Variability of thermosphere and ionosphere responses to solar flares (2011, methodology): “The TIME‐GCM will be used to include any possible effect of upward propagating waves, which is not as well represented in the TIE‐GCM [Qian et al., 2009].”
• NRLMSIS 2.0: A Whole‐Atmosphere Empirical Model of Temperature and Neutral Species Densities (2020, methodology): “In physics‐based models, subgrid‐scale mixing parameterizations typically have to be tuned to produce the observed upper thermosphere (e.g., Qian et al., 2009).”
• Development and Validation of the Whole Atmosphere Community Climate Model With Thermosphere and Ionosphere Extension (WACCM‐X 2.0) (2018, background): “The thermosphere and ionosphere are integral parts of the whole atmosphere system, and more recent perspectives emphasize the importance of lower atmospheric dynamics and chemistry, including weather systems, gravity waves, planetary waves, tidal variations, seasonal cycles, and long-term climate ch”
