A new analysis of the airglow spectra recorded by the UV spectrometer SPICAM onboard Mars Express is presented, with emphasis on the CO Cameron bands, the CO+2 (B-X) UV and OI (2972Å) emissions. Exospheric/ thermospheric temperatures are retrieved from the individual dayglow altitude profiles using a direct fit of the emission profiles by a set of barometric and Epstein functions and by adjusting the forward kinetic transport model Aeroplanets to fit the emission profiles. It is suggested that the CO+2 emission is the best candidate for an accurate retrieval of exospheric temperatures. Variations with solar longitude of the exospheric temperatures are investigated by the MTGCM global circulation model and compared with the observations. Reasonable agreement with observations is found for solar longitudes ranging from 140 to 300 , for solar minimum to moderate conditions.
