Ionosphere and Upper Atmosphere Research with Radars

Mars: upper atmosphere.

The thermal structure of the upper atmosphere of Mars has been theoretically investigated. The exospheric temperature, for a pure CO(2) model atmosphere, lies between 400 degrees and 700 degrees K. The origin of the Martian atmosphere is discussed in the light of these results.

Study of the Martian Upper Atmosphere using Radio Tracking Data

Since the first in situ observations of the Martian atmosphere were made by the twin Viking landers, we have learned considerably more about its composition, dynamics and variability. Not only did the new data on global atmospheric densities generate opportunities to understand the atmospheric composition of early Mars and supply constraints at the upper limit of General Circulation Models, it ...

The Use of Fourier Transforms for Asynoptic Mapping: Applications to the Upper Atmosphere Research Satellite Microwave Limb Sounder

Fourier analysis has been applied to data obtained from limb viewing instruments on the Upper Atmosphere Research Satellite. A coordinate system rotation facilitates the efficient computation of Fourier transforms in the temporal and longitudinal domains. Fields such as ozone (03), chlorine monoxide (C1O), temperature and water vapor have been transformed by this process. The transforms have be...

Waves in Pluto’s Upper Atmosphere

Observations of the 2007 March 18 occultation of the star P445.3 (2UCAC 25823784; R = 15.3) by Pluto were obtained at high time resolution at five sites across the western United States and reduced to produce light curves for each station using standard aperture photometry. Global models of Pluto’s upper atmosphere are fitted simultaneously to all resulting light curves. The results of these mo...
