Abstract :
[en] Limb observations of airglow emissions is a standard technique to study the altitude profiles of the chemical elements in the Martian atmosphere and its thermal structure. Several previous missions have performed observations in the past (Mariners, Mars express). Recently the IUVS Ultraviolet spectrograph (McClintock et al. 2014) on board MAVEN has been collecting thousands of airglow
(Jain et al. 2015) or auroral (Schneider et al., 2015) limb prof iles in the range 120 to 340 nm. We have analysed more than three years of airglow observations and compared them to model simulations.
The objective is to study the CO2, O, CO
and other density prof iles as well as
thermospheric temperatures.
