Effects of a mid-latitude solar eclipse on the thermosphere and ionosphere - A modelling study [PDF]
, 1998 A modelling study is presented which investigates in-situ generated changes of the thermosphere and ionosphere during a solar eclipse. Neutral temperatures are expected to drop by up to 40 degrees K at 240 km height in the totality footprint, with ...

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.

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.

Eos, Transactions American Geophysical Union, 2007 Recent decades have seen great progress in computer modeling of the global thermosphere‐ionosphere system. The models are derived by solving simultaneously the conservation equations of mass, momentum, and energy that govern the concentrations, velocities, and temperatures of the ions, electrons, and neutral gases.

Journal of Space Weather and Space Climate, 2013 The thermospheric atomic oxygen red line is among the brightest in the auroral spectrum. Previous observations in Longyearbyen, Svalbard, indicated that it may be intrinsically polarized, but a possible contamination by light pollution could not be ruled
