Abstract
The atmospheric fluorescent emissions of CO2 at 4.3- um have been observed in the daytime upper atmosphere of Mars from a limb geometry by the instruments OMEGA and PFS on board Mars Express [1, 8]. 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 data
