Seasonal and interannual variations of H2O2 on Mars

Abstract : Following a long-term monitoring campaign on the abundance and distribution of hydrogen peroxide on Mars, we present a new observation near summer solstice which corresponds to a maximum of the seasonal abundance of H2O2. Our result is in full agreement with GCM predictions (Lefèvre et al. 2008; [1]). We also analyse previous measurements of H2O2 in the vicinity of aphelion which seem to indicate the existence of interannual variations, and we discuss their possible origin.
