Distribution of ozone in the Arctic over time

Caption

The graph depicts the total column ozone (TCO), or the total amount of ozone in a vertical column extending from the Earth's surface to space, over time. The annual (blue) and March month (red) TCO measurements are illustrated in the graph by satellite (top panel), reanalysis (second from the top), and ground-based (Lerwick, Oslo, Sodankylä, and Scoresbysund) observations in the Arctic between 1978–2024. The pink lines in the background show the observed high TCO years.
