Temperature variations in Titan’s upper atmosphere: Impact on Cassini/Huygens
Temperature variations of Titan’s upper atmosphere due to the plasma interaction of the satellite with Saturn’s magnetosphere and Titan’s high altitude monomer haze particles can imply an offset of up to ±30 K from currently estimated model profiles. We incorporated these temperature uncertainties as an offset into the recently published Vervack et al. (2004) (Icarus, Vol. 170, 91–112) engineer...

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.
متن کاملEffects of Tsunamis on the Upper Atmosphere
Following the early suggestion of Peltier and Hines [1], it is now generally accepted that tsunamis can excite acoustic-gravity waves, and that these waves can propagate to the upper atmosphere. Because of the decrease of atmospheric density with increasing altitude, conservation of wave energy causes the wave disturbance amplitudes to increase with increasing altitude. At high altitudes molecu...
متن کاملWaves 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...
