Long-term and seasonal variability has been investigated and trends in the change in the total atmospheric ozone and ultraviolet radiation have been revealed according to the data of observation stations at different latitudes: Arctic polar (Alert), Antarctic polar (Palmer), equatorial zone of the Northern hemisphere (Paramaribo), middle latitudes at the South coast of Crimea (Katsiveli), and the closest Turkish coast across the Black Sea (Samsun). The ecologically negative trends of TO decrease and UV increase in the Arctic are revealed. In Antarctica, there are ecologically positive trends in TO increase and UV decrease, however, during 2019, 2020, TO decreases, and UV increases. In the equatorial zone of the Northern Hemisphere, there is no noticeable increase or decrease in TO. On the South coast of Crimea, an insignificant but ecologically positive trend of TO increase is revealed, which should contribute to a decrease in UV. In contrast to the South coast of Crimea, on the Turkish coast, there is a downward trend in TO, probably due to the prevailing opposite directions of the atmospheric circulation flows over the central northern and southern coasts of the Azov-Black Sea basin. © 2021 SPIE.
