This colourful video tracks the behaviour of the ozone layer over Antarctica across all of 2016.

It shows clearly the annual "hole" that appears above the South Pole in the austral springtime, and which last year grew to about 23 million sq km (9 million sq miles) in extent.

The visualisation comes from a model run by Europe's Copernicus Atmosphere Monitoring Service.
