Assimilation of thermospheric measurements for ionosphere‐thermosphere state estimation [PDF]
Radio Science, 2016 AbstractWe develop a method that uses data assimilation to estimate ionospheric‐thermospheric (IT) states during midlatitude nighttime storm conditions. The algorithm Estimating Model Parameters from Ionospheric Reverse Engineering (EMPIRE) uses time‐varying electron densities in the F region, derived primarily from total electron content data, to ...

Thermospheric nitric oxide is modulated by the ratio of atomic to molecular oxygen and thermospheric dynamics during solar minimum [PDF]
Atmospheric Chemistry and PhysicsThe formation of nitric oxide (NO) by geomagnetic activity and EUV photoionization in the upper mesosphere and lower thermosphere, and its subsequent impact on ozone, contributes to the natural forcing of the climate system, and has been recommended to ...

Impacts of Lower Thermospheric Atomic Oxygen on Thermospheric Dynamics and Composition Using the Global Ionosphere Thermosphere Model [PDF]
Journal of Geophysical Research: Space Physics, 2020 AbstractThe exchange of energy between the lower atmosphere and the ionosphere thermosphere system is not well understood. One of the parameters that is important in the lower thermosphere is atomic oxygen. It has recently been observed that atomic oxygen is higher in summer at ∼95 km.

The thermosphere of Titan [PDF]
Journal of Geophysical Research: Space Physics, 1984 The diurnal variation of the vertical structure of Titan's thermosphere is calculated through simultaneous solution of the equations of heat transfer and hydrostatic equilibrium. The temperature and density profiles are found above the mesopause. The dynamical response of the thermosphere to heating is for the most part neglected.
