Initial analysis using non-local thermodynamic equilibrium (NLTE) models show that the emissions are well understood [7, 3, 6]. Yet they have not been exploited to derive important thermospheric parameters, like CO2 densities and temperatures. Our major goals are to improve current NLTE models with a joint study of OMEGA and PFS data, and to build an ambitious state-of-the-art NLTE retreival scheme for Mars. Recent progress has been made in these directions on Mars, Venus and Earth. We will present a summary of these efforts and the difficulties and expectatives for its application to the Mars Express dataELETTRONICOenConference abstracthttps://www.epsc2015.eu/2015EPSC...10..663LFIS/05 - ASTRONOMIA E ASTROFISICA
