This indicator measures the thickness of total column ozone in Dobson Units observed above Lauder, Otago. We report minimum, average, and maximum annual total column ozone for each year from 1979 to 2019, and trends. We also report minimum, average, and maximum daily average column ozone by day of year from 1979 to 2019.
