Ozone vertical distribution on Mars from SPICAN/MEX UV occultations

International audienceWe have achieved a four-year cli- matology of the O3 vertical distribution using SPICAM UV occultations. The climatology con- firms the overall behaviour of O3, but reveals some discrepancies in comparison with a global climate model.We are presenting here a simple way to overcome the problem when comparing models and observations; direct comparison of slant profiles (i.e., without doing the vertical inversion)
