Follow the Antarctic ozone hole online

The Antarctic ozone hole usually reaches its maximum size between mid-September and early October.

This year, according to NASA and National Oceanic and Atmospheric Administration (NOAA) scientists, the ozone hole formed more slowly but then quickly expanded to cover a larger area of low ozone values than the past few years.

EUMETSAT's Metop polar-orbiting satellites play a key role in helping to monitor global ozone concentrations with their onboard GOME-2 instruments.
