Version 3.4.1 of the BS Filled Total Column Ozone (TCO) database provides an extension in time of the BS Filled TCO database v3.4. Please refer to version 3.4. (doi:10.5281/zenodo.3908787) for details on the creation of the database. Please note: For the reasons detailed in this document, versions 3.5.x of the BS Filled TCO database and of the NIWA-BS TCO database should not be used henceforth for trend analysis and, as such, we have updated the version 3.4 of BS Filled TCO database to the end of 2019 (now referred to as version 3.4.1 of the database) as a replacement. You can also access the unfilled version of this database at doi:10.5281/zenodo.7447660. Please email greg@bodekerscientific.com and let us know which data set you downloaded and what your intended purpose for the use of the data is. You will then receive updates if an improved version becomes available.
