Short summary

This study examined changes in the total ozone column above three Antarctic stations in 2007–2023 using ground and satellite observations. Ozone changes were mainly influenced by stratospheric temperature and atmospheric circulation. A significant increase occurred at Marambio, and unusually warm conditions in September 2019 caused ozone to rise strongly over East Antarctica, improving understanding of how the ozone layer responds to environmental changes.
