IUVS observation of Mars’ ozone column

The geographical distribution of ozone in the southern hemisphere of Mars, imaged by MAVEN’s Imaging Ultraviolet Spectrograph. On Mars, ozone is primarily destroyed by the combined action of water vapor and sunlight. The cold, dark conditions near the pole allow ozone to accumulate there.
