6. Abstract

We propose to analyze high-resolution H2 emission spectra of Jupiter's aurora
obtained by STIS during the Cassini-Jupiter flyby campaign of 12/2000-1/2001. We
will use a recently modified version of an interactive electron transport model
coupled with an H2 synthetic spectral generator to extarct information on energetics
of precipitating electrons. We will then use this information (along with other
quantities, such as temperature and composition) to constrain our newly-developed
Jupiter Thermosphere General Circulation Model (JTGCM). The results will enhance our
understanding of how the Jovian aurora manages to affact its upper atmospheric
dynamics and thermal structure on a global scale.
