O2(1Δg) dayglow at 1.27 μm reflects the ozone distribution in the Martian atmosphere as a result of ozone photolysis by solar UV radiation. SPICAM IR on Mars-Express performed continuous observations of the O2 dayglow at limb and nadir from 2004 to 2012 with resolving power of 2200. The results of O2(1Δg) observations have been compared with LMD GCM simulation [1-3] to study its seasonal variations and sensitivity to kinetic parameters.
