SA31A:
Composition and Temperature of the Thermosphere I Posters


Session ID#: 8415

Session Description:
A number of current and future space missions involve studying neutral composition and temperature in the upper atmosphere. In parallel with this experimental work, new theoretical studies are making considerable progress in determining how and why the composition and temperature of the thermosphere changes. It is therefore timely to have an AGU session that covers various aspects of thermospheric composition and temperature and brings together diverse studies of these subjects. Topics include, but are not limited to: observations and modeling of O and N2 and their relationship to the ionosphere; total neutral density; minor species in the thermosphere; the role of minor species in cooling the thermosphere; the transition from a mixed to a heterogeneous atmosphere; composition change during geomagnetic storms; temperature changes in the upper atmosphere; and the influence of composition changes on the ionospheric F2 peak and the topside ionosphere.
