Abstract : We report here on OMEGA/MEx day-side limb observations of non-Local Thermodynamic Equilibrium (non-LTE) CO2 emission at 4.3 μm. Since January 2004 more than 500 limb profiles have been acquired at various locations, seasons and illuminations. The variability of the non-LTE emission with latitude, altitude, solar illumination and season was analyzed and compared to predictions derived by non-LTE model.
