UTLS Ozone Data Sets

According to the UTLS Ozone Data Protocol,
Data should be submitted at the latest 6 months after their production unless otherwise stated in the implementation plan.

Data will be released 18 months after their submission.
For practical reasons, it has been decided, in agreement with the UTLS Ozone Steering Committee, that data provided by a single project will all be released at the same date even when produced or submitted at different dates. Furthermore, when the submission date is unknown or when submission has taken place much later than required, the release date will be 2 years after the data production, unless the data provider objects to it.

The UTLS Ozone archive (top level directory /badc/utls/) currently contains the following data and documentation.
