Polar heating in Saturn's thermosphere

Müller-Wodarg, I. C. F.; Miller, S.; Smith, C. G. A. +1 more

A 3-D numerical global circulation model of the Kronian thermosphere has been used to investigate the influence of polar heating. The distributions of temperature and winds resulting from a general heat source in the polar regions are described. We show that both the total energy input and its vertical distribution are important to the resulting t…

Temperature variations in Titan's upper atmosphere: Impact on Cassini/Huygens

Lammer, H.; Rucker, H. O.; Fischer, G. +5 more

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 ±30K from currently estimated model profiles. We incorporated these temperature uncertainties as an offset into the recently published Vervack et…
