Aqua-planet ozone specification

    Many of the available UM ozone ancillary files have zonal average values of ozone so are suitable for use in aqua-planet integrations. It should be borne in mind however that the fields are not hemispherically symmetric so this will introduce an asymmetry into the model. If this is important then a new ancillary may need to be created. The most important thing is to use an ozone ancillary with the correct number of vertical levels, and to make sure that the "configure" option is chosen in the UMUI rather than the "update" option if the forcing is to be fixed at equinoctial values. The ozone ancilary provided in the tar file is for a standard 19 vertical level experiment.

    The ozone file provided in the tar file is called aqua.ozone
