   Thermosphere and Ionosphere Definitions. Thermosphere: neutrals. Layers are divided based on temperature gradient. Starting from the coldest region at mesopause to several hundred km. Ionosphere: plasma. Layers are divided based on plasma density. Starting from about 80 km to several hundred km. Thermosphere and Ionosphere Density Profiles.

   The thermosphere is the atmospheric region from ∼85 to ∼500 km altitude, containing the ionosphere. It is characterized by high temperature and large variability, in response to changes in solar ultraviolet radiation and solar-driven geomagnetic activity.

   5 sie 2011 · Abstract. Neutral density shows complicated temporal and spatial variations driven by external forcing of the thermosphere/ionosphere system, internal dynamics, and thermosphere and ionosphere coupling. Temporal variations include abrupt changes with a time scale of minutes to hours, diurnal variation, multi-day variation, solar-rotational ...

   UCAR/Randy Russell. The thermosphere is a layer of Earth's atmosphere that is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above Earth's surface.
