Abstract :
[en] Recently, Stallard and coworkers observed an event in Jupiter's auroral polar regions that resulted in a temperature increase of around 125K during the period of approximately seven jovian rotations [1]. This "auroral event" involves a great deal of energy being deposited in the upper atmosphere - up to 250mW m[SUP]-2[/SUP]. Stallard et al. made these measurements using H_3^+ emission lines from the fundamental (v=1 rightarrow 0) and hotband (v=2 rightarrow 1) manifolds around 4μm. In this poster, we use the temperature profiles developed by Grodent and coworkers [2] in their one-dimensional model of the jovian aurorae to demonstrate that the lines used by Stallard et al. are formed at different altitudes in the atmosphere: the hotband is formed higher than the fundamental. We show a series of profiles, based on Grodent {et al.}'s original model that can be used to interpret future jovian spectra. [1] T. Stallard et al., 2002. Icarus 156, 498-514. [2] D. Grodent, J.
