Sentinel-5P (http://m.esa.int/Our_Activities/Observing_the_Earth/Copernicus/Sentinel-5P/Downloads) data is available for download since July 2018 to monitor air quality and changes in ozone over Antarctica
This high spatial resolution data is useful for air pollution to locate origin of key pollutants (trace gases such as sulfur dioxide in the atmosphere) and finding pollution hotspots. Measurements of atmospheric ozone from the Copernicus Sentinel-5P satellite are now being used in daily forecasts of air quality.
The Sentinel-5P data in “pre ops” phase can be downloaded from the scihub https://scihub.copernicus.eu/ . I downloaded a level 2 NO2 file in netCDF format (.nc files).

The downloaded netcdf file first imported into “Panoply netCDF Visualization Software”

One added value of Copernicus Atmosphere Monitoring Service (CAMS) ozone products compared to satellite total column retrievals is that CAMS provides 3D global fields. This allows structures like the Antrctic ozone hole to be viewed in a different way. This animation shows a cross section of the ozone layer (in partial pressure) over the South Pole from 1 July to 25 November 2018 and illustrates the development and recovery of the ozone hole.

The reduction of ozone concentrations in the stratosphere and the formation of the ozone hole each year are caused by complex meteorological and chemical processes. Changes in the ozone between 7 July and 22 November 2018 are displayed here as a 3D rendered animation.
