Ozone hole over Antarctica

 This year's ozone hole over the South Pole region reaches immense dimensions. The minimum temperature at 50 hPa is still below -75°C, below the level when polar stratospheric clouds can form. This is unique for this time of the year. Also, the absolute minimum of the total ozone column is still below the record years. And forecasts are not showing rapid improvements. It means that levels of UV radiation reaching the surface in these southern regions are very high and respective protective measures are needed. U-to date information can be found on the website of the Copernics Atmospheric Monitoring Service (CAMS) for the ozone layer monitoring
