A solar cycle of upper thermosphere density observations from the EISCAT Svalbard Radar : thermospheric density over Svalbard

, 2014
We exploit a recently developed technique, based on ion-neutral coupling, which allows estimations of the upper thermospheric neutral density using measurements of ionospheric plasma parameters made by the European Incoherent Scatter (EISCAT) Svalbard Radar (ESR).

A new approach to mass spectrometer measurements of thermospheric density [PDF]

The gas sampling problem in satellite and high velocity probes was investigated by applying the theory of a drifting Maxwellian gas. A lens system using a free stream ion source was developed and experimentally evaluated over the pressure range of 0 ...

Environmental definition of the earth's neutral atmosphere [PDF]

Although number densities are low at altitudes where spacecraft typically operate, high orbital speeds result in incident fluxes and collisional energies large enough to interact with and degrade material surfaces.
