Short summary

The source of ozone-depleting compounds in the remote troposphere has been thought to be long-range transport of secondary pollutants such as organic nitrates. Processing of organic nitrates to nitric acid and subsequent deposition on surfaces in the atmosphere was thought to remove these nitrates from the ozone–NO_x–HO_x cycle. We found through observation of NO_x in the remote tropical troposphere at the Cape Verde Observatory that surface nitrates can be released back into the atmosphere.
