Total column ozone: MetOp-B and MetOp-C weather satellite measurements
This image shows the total column ozone in Dobson units (DU) and is based on combined measurements from the GOME-2 instruments on the European weather satellites MetOp-B and MetOp-C. A region of low ozone concentration (black) is distinctly recognisable above the Antarctic – known as the ozone hole. This phenomenon typically occurs in the autumn and winter months in the southern hemisphere, as confirmed here by measurements from 31 October to 2 November 2025. MetOp-B has been in operation since 2013, and MetOp-C since 2018. The GOME-2 instruments provide continuous, global measurements of trace gases and air pollutants such as ozone, nitrogen dioxide, sulphur dioxide, bromine monoxide and formaldehyde.
